Scientists Love Addgene

Addgene has been an exceptionally useful resource for us, both because they can be trusted to supply our plasmids to other labs efficiently, and because we ourselves are constantly ordering reagents of interest that other labs have deposited. Keep up the good work!

Our optogenetic tools are sweeping throughout neuroscience, helping scientists figure out how the brain works. Without Addgene helping provide these to the world, neuroscience would be moving at a much slower pace.
