Background

EPO is a 34 kDa protein that is required for the survival and terminal differentiation of erythrocytes (1). EPO is produced by a number of cell types including tubular endothelial cells, interstitial cells, hepatocytes, Kupffer cells, astrocytes, and Schwann cells (2-4). EPO inhibits apoptosis and may protect neuronal cells from death during ischemia and/or neurodegenerative diseases (3,4). EPO inhibits the production of pro-inflammatory cytokines through inhibition of NF-κB signaling (5). EPO protected against the development of diabetes in an animal model by promoting pancreatic β cell survival and growth (6). Binding of EPO to its cognate receptor, EPOR, induces activation of Jak2, Stat5 and Akt (3-5).

Endotoxin

Less than 0.01 ng endotoxin/1μg hEPO.

Purity

>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant hEPO. All lots are greater than 98% pure.

Source / Purification

Recombinant human Erythropoietin (hEPO) Ala28-Arg193 (Accession #NP_000790) was expressed in human 293 cells at Cell Signaling Technology.

Bioactivity

The bioactivity of recombinant hEPO was determined in a TF-1 cell proliferation assay. The ED50 of each lot is between 50-400 pg/ml.
