Scientific Data Images for Human CNTFR alpha Antibody

Detection of CNTFR alpha in Human Skeletal Muscle.

CNTFR alpha was detected in immersion fixed paraffin-embedded sections of Human Skeletal Muscle using Mouse Anti-Human CNTFR alpha Monoclonal Antibody (Catalog # MAB303) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to sarcolemma and sarcoplasm of skeletal muscle cells.

Background: CNTFR alpha

The high-affinity CNTF receptor complex, which mediates the biological action of CNTF, contains three proteins: the ligand-binding alpha subunit (CNTF R alpha), and the two signal-transducing proteins LIF R beta and gp130. Whereas LIF R beta and gp130 are widely expressed in many cell types, the expression of CNTF R alpha is restricted to the central and peripheral nervous systems. cDNAs encoding human and rat CNTF R alpha share 94% amino acid (aa) sequence identity. Human CNTF R alpha cDNA encodes a 372 aa  precursor protein with a 22 aa residue signal peptide and four potential glycoslyation sites. CNTF R alpha differs from other cytokine receptors in that it lacks transmembrane and cytoplasmic domains and is anchored to cell membranes by a glycosylphosphatidylinositol (GPI) linkage. Similar to other GPI-linked proteins, soluble CNTF receptor alpha (CNTF sR alpha) can be released from the cell surface by phosphatidylinositol-specific phospholipase C. CNTF sR alpha can be released from skeletal muscle in response to peripheral nerve injury and high concentrations of CNTF sR alpha have also been detected in human cerebrospinal fluid. CNTF sR alpha binds CNTF in solution and the complex can act on cells that express only LIF R beta and gp130 but not CNTF R alpha.
