• 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.

  • 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

  • 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!

    Frank Borriello

    Alloplex Biotherapeutics, USA

  • 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.

    Alexander Mayer

    University of Würzburg, Germany

  • VectorBuilder is an intuitive tool to help your need in developing vectors at an affordable price. I was in need of a CRISPR Lentiviral system with a Puro selection 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 had good knockdown clones. I definitely will be ordering more vectors from Cyagen to finish up my thesis!

    Christophe Langouet-Astrie

    University of Colorado, Denver

  • Amazing experience with VectorBuilder! Ordered plasmids 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 time at my institute. Overall, I am super 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 began to use VectorBuilder to prepare adenoviral plasmids about a year ago. We normally handled all the cloning stuffs ourselves, but when it comes to adenoviral vectors, because of its large size, sometimes it is kind of tricky for inexperienced students. We decided to give a try on VectorBuilder. One month later, the plasmid arrived and it generated virus that expressed the correct gene. After that, we have ordered more than 10 adenoviral plasmids and they all work fine. VectorBuilder did save us a lot of time.
