Description
Human Activin-A Recombinant Protein Lyophilized has been recombinantly produced in E Coli.
Activin A is a TGF-beta 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-beta anTagonist, follistatin. Recombinant human Activin A is a 26.0 kDa disulfide-linked homodimer of two betaA chains, each containing 116 amino acid residues
