| 背景 | Erythropoietin (Epo) is a 34 kDa glycoprotein hormone in the type I cytokine family and is related to thrombopoietin. Its three N-glycosylation sites, four alpha helices, and N- to C-terminal disulfide bond are conserved across species. Glycosylation of Epo is required for biological activities in vivo. Mature human Epo shares 75%‑84% amino acid sequence identity with bovine, canine, equine, feline, mouse, ovine, porcine, and rat EPO. Epo is primarily produced in the kidney by a population of fibroblast-like cortical interstitial cells adjacent to the proximal tubules. It is also produced in much lower, but functionally significant amounts by fetal hepatocytes and in adult liver and brain. Epo promotes erythrocyte formation by preventing the apoptosis of early erythroid precursors which express the Epo receptor (Epo R). Epo R has also been described in brain, retina, heart, skeletal muscle, kidney, endothelial cells, and a variety of tumor cells. Ligand induced dimerization of Epo R triggers JAK2-mediated signaling pathways followed by receptor/ligand endocytosis and degradation. Rapid regulation of circulating Epo allows tight control of erythrocyte production and hemoglobin concentrations. Anemia or other causes of low tissue oxygen tension induce Epo production by stabilizing the hypoxia-induceable transcription factors HIF-1 alpha and HIF-2 alpha. Epo additionally plays a tissue-protective role in ischemia by blocking apoptosis and inducing angiogenesis. |

Cell Proliferation Induced by Erythropoietin and Neutralization by Human Erythropoietin Antibody. Recombinant Human Erythropoietin (Tissue Culture Grade) (Catalog # 287-TC) stimulates proliferation in the TF‑1 human erythroleukemic cell line in a dose-dependent manner (orange line) as measured by Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Human Erythropoietin (Tissue Culture Grade) (0.2 units/mL) is neutralized (green line) by increasing concentrations of Rabbit Anti-Human Erythropoietin Polyclonal Antibody (Catalog # AB-286-NA). The ND50 is typically 3 µg/mL. | |
Erythropoietin in Human Kidney Cancer Tissue. Erythropoietin was detected in immersion fixed paraffin-embedded sections of human kidney cancer tissue using Rabbit Anti-Human Erythropoietin Polyclonal Antibody (Catalog # AB-286-NA) at 10 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rabbit HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS005) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.
