For research Purposes Only. Not for use in diagnostic or therapeutic procedures. 

Description

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 post-menopausal woman 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. Human Activin-A is a 26 kDa disulfide-linked homodimer of two beta A chains, each containing 116 amino acid residues.

Product Specific Information

Reconstitution: We recommend a quick spin followed by reconstitution in water to a concentration of 50 μg/ml (e.g., 5 μg/100μl) will yield a solution of 10 mM Citric Acid, pH 3.0. 

Storage: This solution can then be stored at room temperature or at 4°C for 1 month. It is recommended that further dilutions be made in PBS containing 2 mg/ml albumin and stored at -20°C.
