TPM4 ELISA kits are immunoassay tools for the measurement of the protein tropomyosin 4, which is encoded by the TPM4 gene in humans. Functionally, this protein is known to bind to actin filaments in muscle and non-muscle cells. The canonical protein structure is reported to have an amino acid length of 248 residues, a mass of 28.5 kDa, and is a member of the Tropomyosin protein family. It is known to be localized in the cytoplasm and is notably expressed in cardiac tissue and platelets, the form found in cardiac tissue is a higher molecular weight than the form found in platelets. As many as 2 protein isoforms have been reported. Other alias names for this target include tropomyosin alpha-4 chain, TM30p1, epididymis secretory protein Li 108, and HEL-S-108.
The detection range for different TPM4 ELISA kits can vary, with some assays measuring target concentrations as low as 15 ng/L and as high as 20 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
