Q:

I need a TBG ELISA that would work for recombinant TBG in cell culture supernatant. Is this kit suitable for that?

A:
Thanks for your inquiry.
CSB-E09501H
The standard in this kit is CHO-derived recombinant protein. As we are not clear about the expression system and modifications of recombinant TBG, sorry we are not sure if it can be detected out or not. For this case we can only suggest you do a pretest first. We validated natural samples before and they can be detected out.
