Data Examples

Western Blot Detection of Human Erythropoietin R by Western Blot. View Larger

Detection of Human Erythropoietin R by Western Blot. Western blot shows lysates of UT‑7 human acute myeloid leukemia cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Erythropoietin R Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-322-PB) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). Specific bands were detected for Erythropoietin R at approximately 70-78 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Simple Western Detection  of Human Erythropoietin R by Simple  WesternTM. View Larger

Detection of Human Erythropoietin R by Simple WesternTM. Simple Western lane view shows lysates of UT‑7 human acute myeloid leukemia cell line, loaded at 0.2 mg/mL. A specific band was detected for Erythropoietin R at approximately 76 kDa (as indicated) using 10 µg/mL of Goat Anti-Human Erythropoietin R Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-322-PB) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). 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). The genes for human and mouse Epo R have been cloned and characterized. The full-length human Epo R cDNA encodes a type I membrane-spanning protein with 508 amino acid (aa) residues (a 24 aa residue hydrophobic signal sequence, a 226 aa residue extracellular domain, a 22 aa residue transmembrane domain and a 236 aa residue cytoplasmic domain). At the protein sequence level, the human Epo R is approximately 82% identical to the mouse protein. As a result of alternative splicing of the Epo R gene, cDNA clones encoding a truncated form of the Epo R as well as the soluble form of Epo R has been found. The presence of a soluble form of the Epo R has also been detected on human sera. Recombinant soluble Epo R binds Epo with high affinity and is a potent Epo antagonist.
