Activin-A Recombinant Protein

CATALOG NUMBER: 40-544

Specifications
source-species:
E. coli
Species:
Human
source-species:
E. coli
Recombinant Protein Sequence:
GLECDGKVNI CCKKQFFVSF KDIGWNDWII APSGYHANYC EGECPSHIAG TSGSSLSFHS TVINHYRMRG HSPFANLKSC CVPTKLRPMS MLYYDDGQNI IKKDIQNMIV EECGCS
Biological Activity:
Biological activity was determined by its ability to inhibit the proliferation of mouse MPC-11 cells. The expected ED50 is ≤ 2.0 ng/mL, corresponding to a specific activity of ≥ 5 x 105 units/mg. Endotoxin level is less than 0.1 ng per μg (1EU/μg).
Purity:
Greater than 97% by SDS-PAGE gel and HPLC analyses.
physical-state:
Lyophilized
Storage Conditions:
The lyophilized Activin-A recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted Activin-A stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing Activin-A recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Background:
Activin A is a TGF-β 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 postmenopausal women 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-β antagonist, follistatin. Recombinant human Activin A is a 26.0 kDa disulfide-linked homodimer of two βA chains, each containing 116 amino acid residues.
