产品名称：Recombinant Human EPO  重组人红细胞生成素-α  
产    地：ProSpec
产品货号：CYT-201
产品规格：5μg
产品说明：
Synonyms  Erythropoietin-Alpha, EPO-a, EPO-alpha, Epoetin, EP, MGC138142. 
Introduction  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. 
Description  Erythropoietin-alpha Human Recombinant is produced in Chinese hamster ovary （CHO） cells by recombinant DNA technology is a single, polypeptide chain containing 166 amino acids ａnd having a predicted molecular mass of 21,000 Dalton ａnd apparent glycosylated molecular mass of 36-40kDa Dalton. EPO-a is purified by proprietary chromatographic techniques.
Source  Chinese Hamster Ovary Cells（CHO）. 
Physical Appearance  Sterile Filtered White lyophilized （freeze-dried） powder. 
Formulation  Each mg of lyophilized powder contains 0.59 mg sodium citrate, 0.58 mg sodium chloride ａnd 0.006 mg citric acid.
Solubility  It is recommended to reconstitute the lyophilized Epoetin-a in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability  Lyophilized Erythropoietin-a although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution EPO-alpha should be stored at 4°C between 2-7 days ａnd for future use below -18°C.
For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）.
Please prevent freeze-thaw cycles. 
Purity  Greater than 98.0% as determined by:
（a） Analysis by RP-HPLC.
（b） Analysis by SDS-PAGE.
