Scientific Data

Human Troponin I/TNNI3 ELISA Standard Curve. Recombinant Human Troponin I/TNNI3 protein was serially diluted 2-fold and captured by Mouse Anti-Human Troponin I/TNNI3 Monoclonal Antibody (Catalog # MAB85942) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human Troponin I/TNNI3 Monoclonal Antibody was biotinylated (Catalog # MAB85941) and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background: Troponin I/TNNI3

Troponin I, also known as TNI, is a 24-29 kDa component of a protein complex on striated muscle thin filaments. Troponin I inhibits the calcium-dependent muscle contraction mediated by Troponins C and T. The expression of cardiac Troponin I (TNNI3) is restricted to cardiac muscle, while TNNI1 and TNNI2 (encoded by distinct genes) are expressed in skeletal muscle. Mutations of cardiac Troponin I are associated with heriditary cardiomyopathy. Human cardiac Troponin I shares 93% amino acid sequence identity with mouse and rat cardiac Troponin I.
