Croyez GMP® Activin A, Human
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 A is strongly expressed in wounded skin, and overexpression of Activin A in epidermis of transgenic mice improves wound healing and enhances scar formation. Activin A also regulates the morphogenesis of branching organs such as the prostate, lung, and kidney. There is also evidence showed that lack of Activin A during development results in neural developmental defects.

MLYYDDGQNIIKKDIQNMIVEECGCS with polyhistidine tag at the C-terminus
UnitProt ID:
P08476
Species of Origin:
Human
Expression System:
Escherichia coli
Affinity Tag:
His Tag (C-term)
Endotoxin level:
<0.05 EU per 1 μg of the protein by the LAL method.
Activity:
Measure by its ability to inhibit the proliferation of mouse MPC-11 cells. The ED50 for this effect is <10 ng/mL.
The specific activity of recombinant human Activin A is approximately >1.0 x 103 IU/mg.
Purity:
>95% as determined by SDS-PAGE analysis.
Form:
Lyophilized
Storage Buffer:
Lyophilized from a 0.2 µm filtered solution of PBS containing 0.1% sarkosyl, pH 8.0.
Reconstitution:
It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 0.5 mg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Stability & Storage:
This product is stable after storage at:
• -20°C for 12 months in lyophilized state from date of receipt.
• -20°C or -80°C for 1 month under sterile conditions after reconstitution.
Avoid repeated freeze/thaw cycles.
Shipping conditions:
Blue ice
