Stability and Reconstitution

Stability and Storage Lyophilized proteins are stable for 1 year from the date of receipt if stored between (-20°C) and (-80°C). Upon reconstitution we recommend that the solution can be stored at (4°C) for short term or at (-20°C) to (-80°C) for long term. Repeated freeze thaw cycles should be avoided with reconstituted products.
Reconstitution Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile 1xPBS pH 7.4 containing 0.1% endotoxin-free recombinant human serum albumin (HSA).


Activin A, a member of the TGF-β superfamily, was named for its ability to activate FSH secretion from the anterior pituitary gland (PMID 16885530). Three activins have been identified in human tissues: activin A, activin B, and activinAB, of which activin A is the most studied. Activin A has various functions in regulating cell differentiation, proliferation, apoptosis and carcinogenesis (PMID 8200957). Xeno-free Recombinant Human Activin A is expressed from human 293 cells as disulfide linked homodimers with molecular mass of 25 kDa.
