| Description |
The Rat Cardiac Troponin I (cTn-I) ELISA kit is a ready-to-use microwell, strip plate ELISA kit for the quantitative measurement of rat cTn-I in biological samples, including serum, plasma, and tissue homogenates. It employs the sandwich ELISA technique and enzyme-substrate chromogenic reaction in the detection of target analytes in the samples. This ELISA kit has been quality controlled in multiple characteristics, including sensitivity, specificity, precision, linearity, and recovery. See the product instructions to obtain more information.
cTn-I, a subtype of the troponin family, is currently widely used as a diagnostic biomarker for myocardial injury. It is distributed in cardiac muscle tissue. As a part of the troponin protein complex, cTn-I binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place. It prevents myosin from binding to actin in relaxed muscle. Calcium-binding to the troponin C leads to the dislocation of cTn-I, resulting in tropomyosin leaves the binding site for myosin on actin and subsequent muscle contraction. Because cTn-I is a very sensitive and specific indicator of myocardium damage, Its serum levels can be used to help differentiate between unstable angina and myocardial infarction in people with chest pain or acute coronary syndrome. |

| Linearity |
| To assess the linearity of the assay, samples were spiked with high concentrations of rat cTn-Ⅰ in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. |

| Materials provided |
- A micro ELISA plate ---The 96-well plate has been pre-coated with an anti-Rat cTn-I antibody. This dismountable microplate can be divided into 12 x 8 strip plates.
- Two vials lyophilized standard ---Dilute a bottle of the standard at dilution series, read the OD values, and then draw a standard curve.
- One vial Biotin-labeled cTn-I antibody (100 x concentrate) (120 μl/bottle) ---Act as the detection antibody.
- One vial HRP-avidin (100 x concentrate) (120 μl/bottle) ---Bind to the detection antibody and react with the TMB substrate to make the solution chromogenic.
