Hi, there. Does anyone know which ELISA kit can be used to measure the Free Active TGFb2 in human serum? (I mean the very few natual active form of TGFB2)
Thanks, Rafik. But I think to assay Free Active TGFb2 in human serum, I have to skip the acid activation step, and use a kit that is sensitive enough (the Free Active TGFb2 in human serum may be less than 1% of tatal TGFB2). Did you have experience of using the kit for this kind of assay?
