Technical Data
Erythropoietin, beta, Recombinant, Human (EPO)
Molecular Biology Storage: -20CShipping: RT
Recombinant Human Erythropoietin-beta is produced in Chinese hamster ovary (CHO) cells by recombinant DNA technology is a single, polypeptide chain containing 165 amino acids and having a predicted molecular mass of 21kD and apparent glycosylated molecular mass of 30.4kD.

Dimers and Aggregates:
1% as determined by silver-stained SDS-PAGE gel analysis.

Biological Activity:
Erythropoietin is fully biologically active when compared to standard. The Specific Activity was measured by Normocyth-aemic mice and was found to be 1.2x10e5IU/mg.

0.1ng/ug (IEU/ug) of EPO-b.

Reconstitute the lyophilized EPO-b in sterile 18M -cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Storage and Stability:
Lyophilized powder may be stored at 4C for short-term only. Reconstitute to nominal volume by adding sterile dH2O and store at -20C. Reconstituted product is stable for 12 months at -20C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
Source: CHO cells
Purity: 98% by RP-HPLC, FPLC, or reducing/non-reducing SDS-PAGE Silver Stain. Chromatographically purified.
Concentration: ~0.1mg/ml
Form: Supplied as a lyophlilzed powder in sodium phosphate dibasic, sodium phosphate monobasic buffer, 60% sodium chloride, 0.6% calcium chloride and 0.004% Tween 20.
