"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."

"We have ordered quite a few plasmids from VectorBuilder in the past 1-2 years, ranging from regular expression plasmids, PiggyBac, and AAV vectors. The products have been delivered on time and worked as expected. Highly recommend!"

"VectorBuilder provides fast and economic service for plasmids construction, which saves a lot of time for me. I mostly construct lentivirus plasmids with them and so far have a positive impression for their products. They respond to my requests quickly and honestly so the communication with VectorBuilder’s staffs is one of the best parts of the service."
