  • It has been a great experience working with VB. I was one of the first to test their empty capsid (AAV VLP) service. For my batch capsids were nearly completely empty (>97% by AUC and TEM) and were thus a huge help for assay development as a negative control. I also want to highlight that my contact Matthew Wheeler was always very helpful and transparent for any queries I had and that the team is very agile. A big plus is also the very intuitive website. Overall, a big thumbs up for VectorBuilder from my side.

  • We have used VectorBuilder services for one year. The website is very user-friendly for designing vectors, and there are automatic verifications that make pertinent suggestions when validating sequences. The flexibility of the service is truly amazing, and we can get a perfectly characterized plasmid for the price of an antibody. Working with VectorBuilder saves us a great deal of time, and time is money. We just can't wait to get the plasmid when ordered!

  • Before using VectorBuilder, producing lentiviral overexpression vectors for our in vitro models was a recurring and time-consuming enterprise. We faced frequent challenges in every experimental step, which made it difficult to plan the actual experiments. Setting up the process with VectorBuilder was very efficient, thanks to their great expertise and support. Once we started using VectorBuilder's services, we noticed a substantial increase in productivity as well as a more uniform and predictable transduction pattern of our target cells.

    We went on to use VectorBuilder for a large-scale CRISPR screen with a custom library spanning over 1,600 genes. With the provided virus, we were able to easily maintain cell representation and we derived a number of interesting hit genes, which we are excited to follow up on. A big thank you to the entire VectorBuilder Team!

  • VectorBuilder's AAV serotype panel helped us to choose the best expressing serotype for our brain area and animal model of interest. By piloting injections using a selection of serotypes provided in the panel, we obtained invaluable pilot data before ordering a large scale virus production. This allowed us to save a considerable amount of time and resources. The technical support was great, they answer our questions promptly provided great advice. VectorBuilder technical support team further help us designing and cloning our AAV viral vector. Our preliminary data allowed to map retrogradely labelled neurons in the amygdala using light-sheet microscopy. We would not hesitate to use VectorBuilder for our next projects

  • Vectorbuilder's service is extremely consistent. We started with regular plasmids and AAV plasmids. Since last year we have ordered many piggybac plasmids. All worked as expected.

    Shuhsien Sheu

    Janelia Research Campus, USA

  • We began using VectorBuilder for adenoviral plasmids construction about a year ago. We normally handled all cloning projects ourselves, but when it comes to adenoviral vectors, because of their large size, sometimes the cloning is kind of tricky for inexperienced students. So we decided to give VectorBuilder a try. The plasmid arrived one month later and the virus we generated from it expressed the correct gene. We have ordered more than 10 adenoviral plasmids and they all work fine. VectorBuilder has saved us a lot of time.

  • I recently met one of the VectorBuilder product specialist during AAI-2019 meeting at San Diego Convention Center. Her name is Dr. Swati Roy, and she provided me excellent information regarding their products and vector designs. And then, we recently purchased CRISPR Cas9 dual gRNA vector. Now, we are ordering few more plasmid vectors. As per my experiences, VectorBuilder customer services are excellent and user-friendly. The VectorBuilder product prices are reasonable.

    Shahanshah Khan

  • VectorBuilder’s online vector design platform is user friendly and easy to use. All one needs to do is select sequences of inserts either from their vast data base or provide one’s own unique sequences. The sequence database provides a wealth of information and links to peer-reviewed publications. Placing order for the vectors is easy and their technical and supporting staff are prompt in offering solutions. They offer services at low prices in comparison to other commercial sources. With the guaranteed service, I can concentrate on my experiments instead of constructing the vector. Thanks are especially due to Stella Gideon for her support at every step. If one is constrained with time and manpower to devote to vector construction, leave it to VectorBuilder. It is worth every penny.

  • I would like to share with you my positive experience purchasing a lentiviral vector from VectorBuilder.
     
    First, I am an immunologist and have little experience with cloning. In my recent project, we needed to overexpress a gene in melanoma cells. The transfection efficiency using plasmids in this cell line was extremely low, less than 10%. Then, we tried to use antibiotics to select transfected cells and establish stably expressing cell lines. Unfortunately, for unknown reasons, the ‘stable transfectants’ lost the transfected genes! I was frustrated at this point, until I met VectorBuilder at the EACR conference in Amsterdam. Using the user-friendly website from VectorBuilder, I designed for the first time in my life my own lentiviral vector and got the product in less than one month. My group leader, who has a lot of cloning experience, could not believe that it worked so quickly. Of course, most important are the experimental results. To access the transduction efficiency, I included an EGFP tag in the vector. Now, I can transduce the melanoma cells with nearly 100% positivity. In the following assays, the genes transduced into the tumor cells resulted in a 6-fold induction in tumor immunogenicity.
    Taken together, I strongly recommend VectorBuilder to researchers, especially those who are not so experienced with cloning, and am convinced that the service and product quality from VectorBuilder can further help me to proceed with my own projects more effectively.

  • I have been consistently using VectorBuilder over the last couple of years and have been extremely satisfied with the vectors they've delivered. These include standard over-expression vectors, and Cas9 vectors on the PiggyBac backbone. All of the vectors I have purchased so far have passed my QC and provided reproducible functional data.

    Daksh Thaper

  • VectorBuilder is the best platform for designing and synthesizing constructs. The online vector design tool is so convenient and fun to use. Ms. Joyce Zhang is always very professional in replying my questions and does it so timely. One time, something did not work out, the refund process was smooth and all the staff were very nice and professional. The constructs I asked for had two fluorescent proteins with two promotors, one has NLS and the other does not. I did transfection and it worked out very well. Joyce helped me all through this process, making my life very easy. Basically, I had many pleasant experiences with Vectorbuilder, and I strongly recommend using it. I had tried other companies, they turned out to be either slow or lacked strong technical support or are expensive. Vectorbuilder is not the cheapest, but considering the quality of its service, it is worth the money.

    Shanshan Zhu

    Johns Hopkins University, USA

  • Amazing experience with VectorBuilder! I ordered plasmids at the beginning of December, and despite the holiday season they arrived exactly as scheduled. Furthermore, customer support reached out to ask what would be my desired delivery date, considering potential holiday conflicts at my institute. Overall, I am very satisfied, would highly recommend VectorBuilder (which I already do) and will buy from them again. All the best from my side!

    Tamara Tomin

  • VectorBuilder is efficient and easy to use for the outsourcing of plasmid generations. We used the PiggBac system for transgenic modifications and we have had great success.

    Luis Cruz

    University of California San Diego, USA

  • Using VectorBuilder has transformed the way I do my research. VectorBuilder’s easy-to-use web interface allows me to custom build my own plasmids, freeing up time that I would have wasted cloning and instead letting me focus on the research that really matters. They offer great prices with a fast turnaround time. Their friendly and well-informed technical support team are on hand every step of the way, should you need any help. I would strongly recommend VectorBuilder to anyone wanting to accelerate the progress of their research.

    David M Brown

    University of Nottingham, UK

  • We recently purchased a number of customized plasmids on VectorBuilder. They consisted of expression vectors of two or more ORFs. Our experience was satisfactory, efficient and cost-effective.

    The designing stage was facilitated by the VectorBuilder design tool online, in which many of the most commonly used sequences, like fluorescent proteins, selection drug resistance genes, and fusion or cleavage linkers were readily offered to be picked from the ORF lists. Regarding our specific sequences, once pasted into the corresponding window of the design tool, they were immediately matched with the International Nucleotide Sequence Database Collaboration (DDBJ/EMBL/GenBank) accession numbers and compared to the databases. Where there were discrepancies, we were asked which transcripts/cDNAs we preferred to use.

    After completing the order, in a matter of three to four weeks, we had in our hands 8 of the 10 plasmids, as offered. For the rest of the plasmids we provided the template for a specific sequence. Before proceeding with the cloning, they sequenced it, detected a mutation and corrected it at a low extra cost upon our approval. A week later these corrected plasmids were delivered as well. During the whole process, VectorBuilder’s European team kept a personalized email dialogue with us, enabling us to follow-up and make decisions or accept suggestions about the plasmids.

    We have satisfactorily tested every plasmid now. We think that our decision to work with VectorBuilder has boosted our research by saving us time, resources and enabling us to concentrate more on our experiments.

  • We were searching for a way to outsource the cloning of our vectors and we are very happy with the service. The versatility of the tools make it a great time saver and the vectors were delivered on-time. Lentiviruses packaged are also very reliable and have been very successful in transduction studies in primary cells. Great customer service with fast response times and the team at VectorBuilder are very knowledgeable.

    Kathy Ngo

    Aridis Pharmaceuticals, USA

  • I have been successfully cloning for 3+ years, but the last time we tried generating KO cell lines with CRISPR/Cas9 vectors, we were not successful. This was upsetting, especially since I invested a lot of time in these efforts. Then, by chance, I attended one of VectorBuilder's seminars. Due to their reasonable prices and the fact I could focus my time on other work, we decided to give their lentiviral (dual gRNA) Cas9 plasmid a try. The turnaround time was reasonable, their customer service was excellent and they actually gave feedback about the status of my cloning projects. Their website is also easy to use. But most importantly: using their Cas9 dual gRNA vector, I was able to successfully generate KO cell lines! 

    I recommend VectorBuilder to CRISPRCas9 users without any hesitation. 

    Anna Salamero Boix

    Georg-Speyer-Haus Frankfurt, Germany

  • We have ordered several vectors from VectorBuilder, including regular expression plasmids, targeting vectors and AAVs. The constructs were delivered on time and worked very well. They saved us a lot of time and money. Their design team pays attention to detail and made very useful suggestions. Their customer service is excellent as well. Overall, we highly recommend VectorBuilder.

    Martin Riccomagno

    University of California, Riverside, USA

  • We applied CRISPR cas9 nickase in our study. VectorBuilder helped us design the gRNAs and construct plasmids with double gRNAs and double selection markers (EGFP/puromycin). The gRNA specificity is quite good, better than available online design tools. We got the knockout cell lines in the first run of electroporation with no off-target events. I would recommend VectorBuilder to CRISPR cas9 users.

    Jie Qin

    University Clinic Cologne, Germany

  • I ordered a plasmid vector two years ago. The design on the web platform was easy. Contacts with the specialists to arrange further details were excellent: they were very supportive!

  • I purchased a lentivirus vector and received it in less than two weeks. I am so glad that I found VectorBuilder, so I can design my lentiviral vector by picking any promotor, and from a variety of antibiotic selection markers and fluorescent tags. Upon transducing several cell lines, my target genes were highly and stably expressed with expression persisting for at least after one month after undergoing selection.

    Xianghong Chen

    H. Lee Moffitt Cancer Center & Research Institute, USA

  • VectorBuilder is an intuitive tool for developing vectors at affordable prices. I was in need of a CRISPR lentiviral system with a Puro selection cassette due to working with delicate cells that cannot handle FACS sorting pressures. With their online interface, it was easy to construct the vector I wanted and received the vector in a timely manner! It was simple to produce virus and test it in our cell culture and generated clonal cells with good gene knockdown. I definitely will be ordering more vectors from VectorBuilder to finish up my thesis!

    Christophe Langouet-Astrie

    University of Colorado, USA
