Purity |
Greater than 80% as determined by SDS-PAGE. |
Description |
EPO a Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 189 amino acids (28-193a.a.) and having a molecular mass of 20.9kDa.EPO a is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. |
Protein Background |
EPO a is a member of the EPO/TPO family and encodes a secreted, glycosylated cytokine composed of four alpha helical bundles. EPO a is found in the plasma and regulates red cell production by promoting erythroid differentiation and initiating hemoglobin synthesis. EPO a also has neuroprotective activity against a variety of potential brain injuries and antiapoptotic functions in several tissue types. |
Expression host |
Escherichia Coli. |
Synonyms |
Erythropoietin, EP, INN=Epoetin, EPO a, Erythropoietin-alpha, EPO. |
Reagent Appearance |
Sterile Filtered clear solution. |
Stability |
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. |
