Detection of Human Phospho-Erythropoietin R (Y426) antibody by Western Blot.

Detection of Human Phospho-Erythropoietin R (Y426) by Western Blot.

Western blot shows lysates of UT-7 human acute myeloid leukemia cell line untreated (-) or treated (+) with 300 ng/mL Recombinant Human Erythropoietin (Tissue Culture Grade) (Catalog # 287-TC) for 10 minutes. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Phospho-Erythropoietin R (Y426) Monoclonal Antibody (Catalog # MAB6926) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Phospho-Erythropoietin R (Y426) at approximately 64 to 70 kDa (as indicated). For additional reference, the membrane was stripped and reprobed with 1 µg/mL of Mouse Anti-Human Erythropoietin R Monoclonal Antibody (lower panel, Catalog # MAB3072). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Human Phospho-Erythropoietin R (Y426) by Simple WesternTM.

Simple Western lane view shows lysates of UT-7 human acute myeloid leukemia cell line untreated (-) or treated (+) with 300 ng/mL Recombinant Human Erythropoietin (Tissue Culture Grade) (Catalog # 287-TC) for 10 minutes, loaded at 0.2 mg/mL. A specific band was detected for Phospho-Erythropoietin R (Y426) at approximately 70 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human Phospho-Erythropoietin R (Y426) Monoclonal Antibody (Catalog # MAB6926). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: Erythropoietin R

Erythropoietin (Epo), a glycoprotein produced primarily by the kidney, is the principal factor that regulates erythropoiesis by stimulating the proliferation and differentiation of erythroid progenitor cells. The biological effects of Epo are mediated by the erythropoietin receptor (Epo R). A member of the hematopoietic growth factor receptor superfamily which includes IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, GM-CSF, G-CSF, Thrombopoietin, LIF, CNTF, Growth Hormone, and Prolactin, Epo R is expressed not only by erythroid cells but also by embryonic stem cells, endothelial cells, and neural cells (1). Mouse Epo R cDNA encode a type I membrane protein with 507 amino acid (aa) residues. Mouse Epo R has a 24 aa hydrophobic signal peptide, a 225 aa extracellular domain, a 22 aa transmembrane domain, and a 236 aa intracellular domain. At the protein sequence level, the human Epo R is approximately 82% identical to the mouse protein (2). Mouse and human Epo R both contain 11 cysteine residues and an N-linked glycosylation site. Mouse Epo R, however, contains two disulfide bridges not found with human Epo R. In common with other hematopoietic growth factor receptor superfamily members, mouse Epo R has 4 positionally conserved cysteines in its extracellular domain, a tryptophan-serine-X-tryptophan-serine (WSXWS) motif or its homolog located near the transmembrane region, and lacks kinase motifs in its intracellular domain. Based on its amino acid composition the molecular weight of Epo R would be 55 kDa but after post translational modification including glycosylation and tyrosine and serine-threonine phosphorylation the molecular weight can be as high as 78 kDa (1). As a result of alternative splicing of the Epo R mRNA, cDNA clones encoding a truncated form of the Epo R as well as a soluble form of Epo R have been found (2, 3). The presence of a soluble form of the Epo R has also been detected in human serum. Recombinant soluble Epo R binds Epo with high affinity and is a potent Epo antagonist (3).
