    Dr. Haopeng Xiao

    Stanford University, 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.

  • 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!

    Dr. Dominic Schmid

    University of Basel

  • 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.
