Scientific Data Images for Rat CNTF Biotinylated Antibody

CNTF antibody in Rat Brain by Immunohistochemistry (IHC-Fr).

CNTF in Rat Brain.

CNTF was detected in perfusion fixed frozen sections of rat brain (midbrain) using Goat Anti-Rat CNTF Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF557) at 1.7 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cell bodies and neuronal processes. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Background: CNTF

Ciliary neurotrophic factor (CNTF) is a polypeptide initially purified from chick embryo ocular tissue and identified as a trophic factor for embryonic chick ciliary parasympathetic neurons in culture. Subsequent studies have demonstrated that CNTF is a survival factor for additional neuronal cell types including: dorsal root ganglion sensory neurons, sympathetic ganglion neurons, embryonic motor neurons, major pelvic ganglion neurons, and hippocampal neurons. CNTF has also been shown to prevent the degeneration of motor axons after axotomy. The cDNA for CNTF encodes a 200 amino acid residue polypeptide that lacks a signal sequence. CNTF is highly conserved across species and exhibits cross-species activities. Human and rat CNTF share approximately 83% homology in their protein sequence. CNTF is structurally related to IL-6, IL-11, LIF, and OSM. All of these four helix bundle cytokines share gp130 as a signal-transducing subunit in their receptor complexes.
