General description

Cardiac Troponin-I (cTnI) is specific to cardiomyocytes and is released into the bloodstream following heart damage. Extensive studies have shown that cTnI is slowly released from damaged cardiomyocytes. This has allowed cTnI to become widely accepted in preclinical and clinical drug development settings as an indicator of myocardial damage and hence, heart damage.The high sensitivity of the research grade Erenna cTnI assay uniquely provides utility across multiple species and matrices.
The SMC® Human cTnI Immunoassay Kit contains all reagents required to perform the assay. This assay takes advantage of a standard immunoassay workflow configured in a standard plate format. Assay protocols are similar to existing sandwich ELISA methods with two key differences: 1) Elution buffer disrupts the sandwich, separating the labeled detection antibody for quantification. 2) The SMC® immunoassay system detects analytes using Single Molecule Counting (SMC®) technology.
