  • VectorBuilder offers a comprehensive online platform for vector design. We found the options for customising our vectors to be extensive and the interface simple - allowing this to be done ‘with a click’. The team has been really responsive when I wanted to check things through - thanks Christina! In my view, VectorBuilder is a platform worth investigating when you are looking to save time and outsource cloning and virus production.

  • We find that it is more efficacious to use VectorBuilder for our molecular biology needs. Purchasing vectors and making use of cloning services frees our students’ time to concentrate on experiments. We have worked with VectorBuilder for quite some time and are always pleased with the efficient, effective, and affordable service. In particular, we are impressed by, and appreciate, how well our rep., Justin Mirus, takes care of our needs. VectorBuilder contributes money and expertise to the advancement of science, for example, to enable conferences at our institute.

  • We recently purchased a lentiviral plasmid for constitutive expression of GFP and luciferase and the corresponding lentivirus from VectorBuilder. We have infected several tumor cell lines with excellent results. The lentiviral stocks worked very nicely, saving us a lot of time. We are now using these modified cell lines for monitoring tumor growth in animal models using in vivo imaging.

  • 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.

  • 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.

  • 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.

  • VectorBuilder’s service makes designing vectors incredibly simple and there’s no software required, it can all be done through their easy to use website. The lentivirus production service is a massive bonus as it’s so quick and reasonably priced. There’s really no reason to make our own lentivirus anymore. Thanks for a fantastic service.

  • 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.

  • 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.
