CERTIFICATE OF ANALYSIS AND DATA SHEET

PRODUCT DESCRIPTION:
This gene is a member of the EPO/TPO family and encodes a secreted, glycosylated cytokine composed of four alpha helical bundles. The protein is found in the plasma and regulates red cell production by promoting erythroid differentiation and initiating hemoglobin synthesis. This protein also has neuroprotective activity against a variety of potential brain injuries and antiapoptotic functions in several tissue types. Erythropoietin-alpha Fc-Chimera Human Recombinant is produced in Chinese hamster ovary (CHO) cells by recombinant DNA technology is a dimeric, glycosilated, polypeptide chain consisting of two mature human EPO molecules linked to the Fc portion of human IgG1. The Fc component contains the CH2 domain, the CH3 domain and hinge region, but not the CH1 domain of IgG1. As a result of glycosylation, the recombinant protein migrates with an apparent molecular mass of 140 kDa in non-reducing SDS-PAGE.

SOURCE: Chinese Hamster Ovary Cells (CHO).

FORMULATION:
Each mg of lyophilized powder contains 1x PBS pH-7.4

PURITY:
Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE

STORAGE:
Although stable at room temperature for 3 weeks, it should be stored desiccated below -18°C. Upon reconstitution it should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

SOLUBILITY:
It is recommended to reconstitute in sterile H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

BIOLOGICAL ACTIVITY: The ED50 as determined by the dose-dependant stimulation of human megakaryoblastic leukemia cells is less than 2.0 ng/ml, corresponding to a Specific Activity of 5.0 x 105 IU/mg.
