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 to 0.2 mg/mL in sterile 1x PBS pH 7.4 containing 0.1% endotoxin-free recombinant human serum albumin (HSA). Gently Swirl or tap vial to mix

Background

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.
