Applications
  •  
    Recommended
    Concentration
    Sample
  • Western Blot
    1 µg/mL
    Recombinant Human Cardiotrophin‑1/CT‑1 (Catalog # 612-CD)
  • Neutralization
    Measured by its ability to neutralize Cardiotrophin‑1/CT‑1-induced proliferation in the TF‑1 human erythroleukemic cell line. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323. The Neutralization Dose (ND50) is typically 1-3 µg/mL in the presence of 20 ng/mL Recombinant Human Cardiotrophin‑1/CT‑1.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Data Examples
Cell Proliferation Induced by Cardiotrophin‑1/CT‑1 and Neutralization by Human Cardiotrophin‑1/CT‑1 Antibody. Recombinant Human Cardiotrophin‑1/CT‑1 (Catalog # 612-CD) stimulates proliferation in the TF‑1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human Cardiotrophin‑1/CT‑1 (20 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human Cardiotrophin‑1/CT‑1 Mono-
clonal Antibody (Catalog # MAB2601). The ND50 is typically 1‑3 µg/mL.

Background: Cardiotrophin-1/CT-1

Cardiotrophin-1 (CT-1) is a member of the cytokine family which also includes IL-6, IL-11, leukemia inhibitory factor (LIF), oncostatin M (OSM), and ciliary neurotrophic factor (CNTF). It was originally isolated based on its ability to induce cardiac myocyte hypertrophy in vitro. CT-1 has since been shown to be a pleiotrophic cytokine with overlapping actions with other IL-6 family members on a variety of cell types. Human CT-1 encodes a 201 amino acid (aa) residue protein that lacks a hydrophobic signal peptide. The mechanism of CT-1 release from cells is currently not understood. Human and mouse CT-1 share 80% aa sequence identity and exhibit cross-species activity. CT-1 is highly expressed in heart, skeletal muscle, liver, lung and kidney. Lower levels of CT-1 expression is also seen in testis and brain. CT-1 initiates downstream signaling pathways through the heterodimerization of gp130 and the LIF receptor beta subunit. A third  alpha receptor subunit has been implicated in the receptor complex.
