| 反应种属 | Rat |
| 应用 | ELISA Capture (Matched Antibody Pair)(2-8 µg/mL ) ELISA Detection (Matched Antibody Pair)(0.1-0.4 µg/mL ) ELISA Standard ( ) |
| 目标/特异性 | Detects rat CNTF in ELISAs and Western blots. In sandwich immunoassays, less than 3% cross-reactivity with recombinant human CNTF is observed. |
| 使用方法 | ELISA Capture (Matched Antibody Pair): 2-8 µg/mL ELISA Detection (Matched Antibody Pair): 0.1-0.4 µg/mL ELISA Standard : Neutralization: Measured by its ability to neutralize CNTF-induced proliferation in the TF‑1 human erythroleukemic cell line. The Neutralization Dose (ND50) is typically 1-3 µg/mL in the presence of 200 ng/mL Recombinant Rat CNTF. |

| 背景 | 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. |

Cell Proliferation Induced by CNTF and Neutralization by Rat CNTF Antibody. Recombinant Rat CNTF (Catalog # 557-NT) stimulates proliferation in the TF‑1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Rat CNTF (200 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Rat CNTF Monoclonal Antibody (Catalog # MAB557). The ND50 is typically 1-3 µg/mL. |
