Protocol
Specificity / Sensitivity
Phospho-Troponin I (Cardiac) (Ser23/24) Antibody detects endogenous levels of cardiac troponin I only when phosphorylated at Ser23/24.This antibody does not cross-react with phosphorylated skeletal muscle troponin I.
Species Reactivity:
Human, Mouse, Rat
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser23/24 of human troponin I (cardiac). Antibodies are purified by protein A and peptide affinity chromatography.
Background
Troponin, working in conjunction with tropomyosin, functions as a molecular switch that regulates muscle contraction in response to changes in the intracellular Ca2+ concentration. Troponin consists of three subunits: the Ca2+-binding subunit troponin C (TnC), the tropomyosin-binding subunit troponin T (TnT), and the inhibitory subunit troponin I (TnI) (1). In response to β-adrenergic stimulation of the heart, Ser23 and Ser24 of TnI (cardiac) are phosphorylated by PKA and PKC. This phosphorylation stimulates a conformational change of the regulatory domain of TnC, reduces the association between TnI and TnC, and decreases myofilament Ca2+ sensitivity by reducing the Ca2+ binding affinity of TnC (1-3).
