Ready-to-use ELISA kits are available for the detection of cardiac troponin I, an alias of the protein, troponin I3, cardiac type. The official gene symbol is TNNI3. The kits can detect several species variants of the protein, including: human, mouse, rat, bovine, primate, and other mammalian. The protein has a mass of 24 kDa and length of 210 residues. It is a member of the Troponin I family and may be known by other names, including: RCM1, CMH7, CMD1FF, troponin I type 3 (cardiac), cardiomyopathy dilated 2A (autosomal recessive), and troponin I cardiac muscle.
