Testimonials

VectorBuilder is proud to share our client's testimonials:

  • 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.

  • 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.

  • 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!

  • 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.

    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.

  • 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.

  • 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!

  • We ordered adenovirus from VectorBuilder to overexpress our protein of interest in primary mouse hepatocytes. The ordering process, including vector design, was very fast and easy. We received the plasmid and adenovirus within the time frame that was stated during the ordering process and the transduction efficiency of the adenovirus was very high, enabling us to use a low MOI. As a bonus, we also received the control Ad-EGFP adenovirus for free. In the future, I will not use any more siRNA or classical transfection methods on primary mouse hepatocytes, just adenoviruses from VB! I can highly recommend VectorBuilder's services for vector design and adenovirus production.
