Data Examples
Western Blot | Detection of Human Cardiotrophin‑1/CT‑1 by Western Blot. Western blot shows lysates of human heart tissue. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human Cardiotrophin‑1/CT‑1 Monoclonal Antibody (Catalog # MAB2602) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # ). A specific band was detected for Cardiotrophin‑1/CT‑1 at approximately 22 kDa (as indicated). This experiment was conducted under reducing conditions and using . |
Immunohistochemistry | Cardiotrophin‑1/CT‑1 in Human Heart. Cardiotrophin‑1/CT‑1 was detected in immersion fixed paraffin-embedded sections of human heart using Mouse Anti-Human Cardiotrophin‑1/CT‑1 Monoclonal Antibody (Catalog # MAB2602) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # ). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in cardiomyocytes. View our protocol for . |
ELISA | Human Cardiotrophin-1/CT-1 ELISA Standard Curve. Recombinant human Cardiotrophin/CT-1 protein was serially diluted 2-fold and captured by Mouse Anti-Human Cardiotrophin/CT-1 Monoclonal Antibody (Catalog # ) coated on a Clear Polystyrene Microplate (Catalog # ). Mouse Anti-Human Cardiotrophin/CT-1 Monoclonal Antibody (Catalog # MAB2602) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # ) followed by Substrate Solution (Catalog # ) and stopping the enzymatic reaction with Stop Solution (Catalog # ). |

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.
