Catalog #: CYT-325
Description:
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.
Synonyms:
EPO-a, EPO-alpha, Epoetin, EP, MGC138142.
Source:
Chinese Hamster Ovary Cells(CHO).
Purity:
Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Solubility:
It is recommended to reconstitute the lyophilized Erythropoietin in sterile 18MΩ–cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
Each mg of lyophilized powder contains 1x PBS pH-7.4.
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.
Activity:
The ED50 as determined by the dose-dependent 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.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Usage:
Denovo Biotechnology's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
