Cardiotrophin-1 (CT-1) is a cytokine. CTF1 gene contains 3 exons, spans over 6 to 7 kb. It is a cardiac hypertrophic factor of 21.5 kDa and a protein member of the IL-6 cytokine family. It is highly expressed in the heart, skeletal muscle, prostate and ovary and to lower levels in lung, kidney, pancreas, thymus, testis and small intestine. CT-1 is associated with the pathophysiology of heart diseases, including hypertension, myocardial infarction, valvular heart disease, and congestive heart failure. This protein exerts its cellular effects by interacting with the glycoprotein 130 (gp130)/leukemia inhibitory factor receptor beta (LIFR) heterodimer.
Principle of the Assay
This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-CT-1 polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-CT-1 polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the CT-1 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of CT-1 can be calculated.
