Erythropoietin, a glycoprotein produced primarily by the kidneys and at lower levels by the liver, is the primary regulatory factor of erythropoiesis. EPO promotes the proliferation, differentiation, and survival of the erythroid progenitors. EPO stimulates erythropoiesis by inducing growth and differentiation of burst forming units and colony forming units into mature red blood cells. EPO produced by kidney cells is increased in response to hypoxia or anemia.
The biological effects of erythropoietin are mediated by the erythropoietin receptor, which binds EPO with high affinity and is a potent EPO antagonist. When EPO is present at low concentrations, the EPO receptor initiates prolongation of G1 in the cell cycle and sends a differentiation signal; whereas at high EPO concentrations, a proliferation signal is generated and the G1 is shortened.

Erythropoietin is a glycoprotein that is the principal regulator of red blood cell growth and differentiation.
Forma física
Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline containing 0.5 mg bovine serum albumin.
Nota de preparación
This Erythropoietin (EPO) is produced from a DNA sequence encoding rat erythropoietin (Met 1-Arg 192). Mature soluble recombinant rat EPO has Ala 27 at the amino terminus. The 166 amino acid residue soluble EPO has a calculated molecular mass of approximately 18.5 kDa. Due to glycosylation, the recombinant protein migrates as a 22-26 kDa in SDS-PAGE. Erythropoietin has been cloned from various species including human, murine, canine, etc. The mature proteins from the various species are highly conserved, exhibiting greater than 80% amino acid sequence identity. Rat EPO cDNA encodes a 192 amino acid residue precursor protein that is processed to yield a 166 amino acid residue mature protein. EPO contains 3 N-linked glycosylation sites. Glycosylation of EPO is required for the biological activities of EPO in vivo.
Nota de análisis
The biological acitivity is measured by its ability to stimulate cell proliferation using TF-1 cell line.

Activation of nitric oxide (NO) signaling is considered, at list partially, a mechanistic basis for EPO-induced cardioprotection. Surprisingly, hemodynamic response subsequent to NO activation after EPO administration has never been reported. The objectives of this study were to evaluate the

Neonatal necrotizing enterocolitis (NEC) is a devastating gastrointestinal disease of preterm infants. Increased intestinal epithelium permeability is an early event in NEC pathogenesis. Autophagy and apoptosis are induced by multiple stress pathways which may impact the intestinal barrier, and they

Chronic kidney disease (CKD) is commonly accompanied by inflammation and anemia; however, the pathogenesis of CKD is unclear. Expression of resistin, a cysteine-rich secretory plasma protein, is correlated with the expression of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and lipoprotein-associated
