Testimonials

VectorBuilder is proud to share our client's testimonials:

  • I have been working with VectorBuilders since 2017 and generated a knock-in Long Evans rat model that recapitulates neuronal and skin disorders found in humans. In addition, we have designed and generate several plasmid constructs with them. In the past year, Ricky Nemeth, PhD, our Territory Manager, has been very supportive and fantastic to work with. In all, the entire team of VB are great to work with as they are responsive to queries and provide us good quality vectors, viral constructs and viral particles.

  • I used their lentiviruses to build a stable cell line with a dual inducible system, and everything worked great. Despite the fact that we are in Chile (South America), VB delivered all the requested materials (lentiviral particles, E. coli colonies and plasmids) successfully and without any delay. They also included lentiviral particles as positive controls in the shipment free of charge. In short, VB can provide you with high quality materials with fast delivery.

    Vitor Oliveira

    Universidade Federal de São Paulo, Brazil

  • Vectorbuilder is timely, communicative, easy to work with, and—most importantly—skilled at producing very high-quality viruses. We have found that the optimal multiplicity of infection for gene-editing experiments using an AAV6 donor supplied by VectorBuilder is lower than other published reports, suggesting that the provided virus is consistently of very high potency. Knowing this saves money and time.

    Dr. Brock Roberts

    Allen Institute for Brain Research

  • We have used VectorBuilder's services for plasmid desisgn as well as AAV and Lentiviral vector production for more than four years years. Their service is consistent, reliable, and prompt. A major plus is the technical support team.

    Dr. Kevin Watt

    Murdoch Children's Research Institute, Victoria, Australia

  • Amazing experience cooperating with VectorBuilder! As one of the most popular technologies, mRNA vaccine technology has been used extensively to develop therapeutics and vaccines targeting various infectious and non-infectious diseases. Recently, Daniel Meng’s R&D team at VectorBuilder rapidly established the IVT mRNA CRO platform, and we closely collaborated on developing mRNA-based HIV and influenza vaccines. I am so impressed by their scientific vision as well as their problem solving capabilities. Once again, VectorBuilder is trustworthy.

    Dr. Caijun Sun

    Sun Yat-sen University, Guangzhou, China

  • 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.

    Dr. Andrei Hutanu

    Analytical Biochemist/QC Method Development, Roche, Switzerland

  • I am very satisfied with the constructions (double mutants) made by Vectorbuilder. The service is very serious and rigorous. They started by verifying our plasmid by doing digestions. As this was not enough, they even sequenced part of the plasmid, which then ensured the success of the constructs. Constant email exchanges for verification steps were ensured with almost instantaneous responsiveness! Quite impressive! Once the sequence was clarified, production was not long, and we were able to do our experiments under excellent conditions. The results were as good as we expected. Bravo again and thank you for the efficiency, the rigor, and the seriousness.

  • To me, science is not a profession. It's a passion for the unknown. It's a constant celebration of perseverance, and love for the truth. And with the professional support of VectorBuilder, the superior quality of VectorBuilder products, and the very competent personalized assistance (thank you so much, Dr. Mirus), science also became an ever-growing source of joy to me. Why? Because since I started to rely on VectorBuilder, I have significantly increased my research output and realized more complex projects much more quickly, giving me time needed to truly enjoy what I'm doing.

    Ricardo Koch

    Institute of Oncology Research (IOR), Switzerland

  • We have used VectorBuilder services for 3 years now. In our lab, we generate different types of vectors, with custom promoters and difficult sequences. I often had trouble when I synthesized these custom elements elsewhere. Going back to cloning by ourselves is no longer our first option since they are fast, efficient and their prices are more than fair. On top of that, their customer service is unbeatable.

    Dr. Gaetano Gargiulo

    Max-Delbrück-Center for Molecular Medicine (MDC), Germany

  • VectorBuilder makes the process of designing and building vectors easy and efficient. Justin Mirus, as the lead, and the unique and energetic design team are promptly ready to help and support our request and advise us with their great expertise and effective services.

    Center for Regenerative Therapies, Germany

  • Two years ago, when another CRO was struggling to provide the requested clones that I ordered, I reached out to Vector Builder to try to make them for me. Very difficult clones to make due to many repeats of amino acids. They got the clones done for me with no issues and very quickly. I have been using Vector Builder since then. Along with this, working with Alejandro Izurieta (California Territory Manager) has been great. He is knowledgeable, and professional promptly answers my request and is courteous. I rely on him to get the service that I need from Vector Builder done. He is just wonderful!

    Irena Levin

  • 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.

    Bala Kolli

    Wayne State University, USA

  • The website design is super user-friendly and easy to follow, I'm really impressed. It was great working with Swati Roy and Stella Gideon. Shout out to the customer support - they have always been responsive and extremely helpful.

    Jaya Pratap Pinnamaneni

    Baylor College of Medicine, USA

  • 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

    Medical University of Graz, Austria

  • 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
