Recombinant Human/Murine/Rat Activin A (Insect derived)

Product Details

Catalogue Number: 120-14

Activin A is a TGF-β family member that exhibits a wide range of biological activities, including regulation of cellular proliferation and differentiation, and promotion of neuronal survival.  Elevated levels of Activin A in human colorectal tumors and in postmenopausal women have been implicated in colorectal and breast cancers, respectively.  The biological activities of Activin A can be neutralized by inhibins and by the diffusible TGF-β antagonist, follistatin.  Activin A binds to the two forms of activin receptor type I (Act RI-A and Act RI-B) and two forms of activin receptor type II (Act RII-A and Act RII-B).  Activins are homodimers or heterodimers of different β subunits.  They are produced as precursor proteins with an amino terminal propeptide that is cleaved to release the C-terminal bioactive ligand.  Recombinant Human/Murine/Rat Activin A is a 26.0 kDa disulfide-linked homodimer of two βA chains, each containing 116 amino acid residues.

A superior product
My lab has been using this product for many years and it always works perfectly. We once purchased it from a different manufacturer due to a relative lower price. However, we found that we must increase the dose if the Activin A is not from Peprotech. As such, the cost went up as we had to use higher dose to make it work. Hence, we learnt that Activin A’s purity and quality from Peprotech is super... reviews.showmore

Excellent Product
I have been using the recombinant Activin A for 5 years for the culture of chicken primordial germ cells (cPGCs) and have had excellent results. PeproTech has been great to work with as well.
