Rat TPM2 (Tropomyosin 2 Beta) Microsample ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat TPM2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat TPM2. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat TPM2, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat TPM2 in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 0.32-20 ng/mL. Sensitivity: 0.116 ng/mL. Assay Type: Sandwich. Standard: 20 ng/mL. Sample Type: sTissue homogenates and other biological fluids.. Assay duration: 3.5h. Protein Function: Binds to actin filaments in muscle and non-muscle cells (PubMed:22812662, PubMed:7568216). Plays a central role, in association with the troponin complex, in the calcium dependent regulation of vertebrate striated muscle contraction (PubMed:22812662). Smooth muscle contraction is regulated by interaction with caldesmon. In non-muscle cells is implicated in stabilizing cytoskeleton actin filaments. The non-muscle isoform may have a role in agonist-mediated receptor internalization (By similarity) [The Uniprot Consortium]
