It's so easy to use. I'm happy with it and recommend it to everyone.

Columbia University
Simple protocol and reproducible results. Would recommend.

University of Houston
I used it for human corneal epithelial cell culture supernatant under induced conditions. It is very sensitive and easy to use.

I also want to comment on the fast delivery of the product.
