(h Troponin I ELISA, Strip Plate)
The Troponin I kit contains all of the components and reagents you need to assay human Troponin I protein in up to 40 duplicate urine or cell free liquid samples (plasma, serum, cell culture supernatant, etc…).
Intended Use: Troponin I ELISA is a direct ELISA for quantitation of Troponin I found in serum, plasma and supernatant. It is for research purposes, and is not intended for diagnostic use.
Kit Contents: The Troponin I ELISA kit contains the following items:
a. 1 Troponin I Assay Plate
b. 1 Troponin I Diluent
c. 1 Troponin I Standard
d. 1 Second Anti-Troponin I antibody
e. 1 HRP conjugated antibody
f. 1 Color Developer
g. 1 Color Stopper
h. 1 Instructions
Technical Background: Troponin I is a complex of three proteins (troponin C, troponin I, and troponin T) that regulate skeletal and cardiac muscle contraction. Cardiac troponin I and T are sensitive and specific indicators of myocardial damage, and their blood levels rise in relation to the extent of injury to heart muscle from various conditions or from drug-induced cardiotoxicity. Cardiac troponins may be usefuls in predicting cardiovascular risk and mortality in the presence of chronic renal disease.
The human troponin I has three separate isoforms: two in skeletal muscle fibers, and one in cardiac muscle. The cardiac isoform (cTnI) has a molecular weight of 22.5 kdaltons and is about 40% different from the skeletal isoforms. Antibodies specific for troponin I do not react immunologically with the other skeletal isoforms and are unique for the cardiac isoform. The Exocell Troponin I ELISA is a direct ELISA using two different affinity purified antibodies to troponin I. The first antibody is coated on a microtitre plate. The second is added to the coated plate after the standards and samples are added. The troponin I reacts simultaneously with the antibody coated on the plate and in solution allowing a “sandwich” of solid phase antibody – troponin I. HRP conjugated antibody is added after an overnight incubation. The free conjugated antibody is washed away allowing the bound HRP- antibody to be detected with a color developer. The amount of Troponin I is directly proportional to the amount of color developed.
Specimen Collection and Storage: Collect samples without preservative, separate and clarify them by centrifugation if necessary. Samples may be stored at 4˚C for up to 1 week or at -60˚C for up to 2 months. Prior to assay, allow the samples to come to room temperature. Do not apply heat to thaw frozen samples.
Specimen Required: Serum, Plasma or tissue extract.
Assay Range: 3.0 – 50.0 ng/ml
Precision: Intra- and inter-assay precision for samples within the assay range have a C.V. of <10%.
