BD Pharmingen™ Mouse Erythropoietin Recombinant Protein - Reactivity Ms

Restrictions: For Research Use only

Stockage

Format: Liquid

Concentration: 0.1 mg/mL

Buffer: Recombinant mouse EPO is supplied as a frozen liquid comprised of 0.22 μm sterile-filtered aqueous buffered solution, and containing 1 mg/mL biotechnology grade, low endotoxin bovine serum albumin, with no preservatives.

Agent conservateur: Azide free

Conseil sur la manipulation: Rapidly thaw and quick-spin product prior to use. Upon initial thawing, the product should be aliquoted into polypropylene microtubes and frozen at -80°C for future use. Alternatively, the product can be diluted in sterile neutral buffer containing not less than 0.5 - 10 mg/ml carrier protein such as human or bovine albumin, aliquoted and stored at -80°C. For in vitro biological assay use, we recommend carrier-protein concentrations of 0.5 - 1.0 mg/ml. For use as an ELISA standard we recommend carrier-protein concentrations of 5 - 10 mg/ml. Failure to add carrier protein or store at indicated temperatures may result in a loss of activity. Carrier proteins should be pre-screened for possible effects in an appropriate experimental system. Carrier proteins may effect experimental results due to toxicity, high endotoxin levels or possible blocking activity.

Stock: -80 °C

Classe de substances: Hormone

Sujet: Mouse erythropoietin (EPO) is a 30 kD heavily glycosylated protein containing 166 amino acids. The carbohydrate residues compose approximately 30 % of the molecule by weight.3 It shares 80 % and 95 % homology with human and rat EPO, respectively. EPO functions as the survival and proliferation factors of late erythroid progenitor cells (CFU-E). In adult mammals, EPO is synthesized almost exclusively in the kidneys.
