Activin and Inhibin are members of the TGF-beta superfamily of cytokines and are involved in a wide range of biological processes including tissue morphogenesis and repair, fibrosis, inflammation, neural development, hematopoiesis, reproductive system function, and carcinogenesis. Activin is strongly expressed in wounded skin, and overexpression of activin in epidermis of transgenic mice improves wound healing and enhances scar formation. Activin also regulates the morphogenesis of branching organs such as the prostate, lung, and kidney. There is also evidence showed that lack of activin during development results in neural developmental defects.

Measure by its ability to induce hemoglobin expression in K562 cells. The ED50 for this effect is <0.85 ng/mL. The specific activity of recombinant human Activin A is approximately >1.4 x 103 IU/mg.
Endotoxin level: <0.1 EU per 1 ug of the protein by the LAL method.
Calculated Molecular Weight: 13.9 kDa
Formulation: The protein was lyophilized from a solution containing 0.1% sarkosyl in 1X PBS, pH 8.0.
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 ug/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Shipping: Blue Ice
Stability and Storage:
Lyophilized protein should be stored at -20 degrees Celsius for 1 year. Upon reconstitution, store at 2 degrees Celsius to 8 degrees Celsius for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20 degrees Celsius or -80 degrees Celsius for 3-6 months.
SDS-PAGE Image Name: human mouse rat Activin A
