Recombinant Human Activin A
$200.00 – $5,000.00
Activin A is a key member of the TGF-β superfamily, essential for proper development and produced by various cell types. It functions as a bioactive disulfide-linked homodimer, binding to Activin receptors (RIA, RIB, RIIA, RIIB) to activate SMAD signaling pathways. This signaling regulates processes such as stem cell maintenance, differentiation, B-cell proliferation, wound healing, metabolism, and gonadal development.
