Purity

Greater than 97.0% as determined by SDS-PAGE.

Biological Activity

The Specific Activity was measured by Normocyth -aemic mice and was found to be 1,000,000 IU/mg.

More Info

  • Introduction

    Darbepoetin is a mutant recombinant human EPO-Alpha protein re-engineered, containing 5 amino acid changes at N30, T32, V87, N88, T90. Darbepoetin exhibits longer half-life stimulating red blood cell production than Erythropoietin. Darbepoetin maintains hemoglobin more effectively compared to EPO-Alpha.

  • Synonyms

    NESP, Novel Erythropoiesis Stimulating Protein, EPO Mutant.

  • Physical Appearance

    Sterile Filtered White lyophilized (freeze-dried) powder.

  • Stability

    Lyophilized Darbepoetin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Darbepoetin 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.

  • Solubility

    It is recommended to reconstitute the lyophilized Darbepoetin in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
