Opis ogólny

EPO has been cloned from various species including human, murine, canine, and others. The mature proteins from the various species are highly conserved and exhibit greater than 80% amino acid sequence identity. EPO contains three N-linked glycosylation sites. The glycosylation of erythropoietin is required for the biological activities of erythropoietin in vivo.

Działania biochem./fizjol.

Erythropoietin (EPO), produced primarily by the kidney, is the primary regulatory factor of erythropoiesis. It promotes the proliferation, differentiation, and survival of the erythroid progenitors. Erythropoietin 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.
Erythropoietin is a glycoprotein that is the principal regulator of red blood cell growth and differentiation.

Uwaga dotycząca przygotowania

Human EPO is expressed as a glycosylated 36 kDa monomer in human HEK 293 cells. Production in human HEK 293 cells offers authentic glycosylation. Glycosylation contributes to stability in cell growth media and other applications.

Komentarz do analizy

The specific activity was determined by the dose-dependent stimulation of the proliferation of human TF-1 cells (human erythroleukemic indicator cell line).

Erythropoietin (EPO) stimulates proliferation of early-stage erythrocyte precursors and is widely used for the treatment of chronic anemia. However, several types of EPO-resistant anemia are characterized by defects in late-stage erythropoiesis, which is EPO independent. Here we investigated regulation of

Patient blood management combines the use of several transfusion alternatives. Integrated use of erythropoietin, cell saver, and/or postoperative drain reinfusion devices on allogeneic erythrocyte use was evaluated using a restrictive transfusion threshold.

Erythropoietin (EPO) is the main hormone that regulates erythropoiesis. Beyond its well-known hematopoietic action, EPO has diverse cellular effects in non-hematopoietic tissues. It has been shown to inhibit apoptosis by activating pro-survival pathways in the myocardium, to mobilize endothelial progenitor

Premature infants are at risk of developing encephalopathy of prematurity, which is associated with long-term neurodevelopmental delay. Erythropoietin was shown to be neuroprotective in experimental and retrospective clinical studies. To determine if there is an association between early high-dose recombinant

During the past century, few proteins have matched erythropoietin (Epo) in capturing the imagination of physiologists, molecular biologists, and, more recently, physicians and patients. Its appeal rests on its commanding role as the premier erythroid cytokine, the elegant mechanism underlying
