Product Information

KE00180 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The t-Plasminogen activator ELISA kit is to be used to detect and quantify protein levels of endogenous t-Plasminogen activator. The assay recognizes human t-Plasminogen activator. An antibody specific for t-Plasminogen activator has been pre-coated onto the microwells. The t-Plasminogen activator protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody specific for t-Plasminogen activator is added to detect the captured t-Plasminogen activator protein. For signal development, horseradish peroxidase (HRP)-conjugated is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information

Plasminogen activator, tissue (PLAT, synonyms: TPA, T-PA) is a tissue-type plasminogen activator, a secreted serine protease which converts the proenzyme plasminogen to plasmin, a fibrinolytic enzyme. Tissue-type plasminogen activator is synthesized as a single chain which is cleaved by plasmin to a two chain disulfide linked protein (33 kDa and 32 kDa). PLAT enzyme plays a role in cell migration and tissue remodeling. Increased enzymatic activity causes hyperfibrinolysis, which manifests as excessive bleeding; decreased activity leads to hypofibrinolysis which can result in thrombosis or embolism. tPA has 4 isoforms produced by alternative splicing with the MW of 63 kDa, 33 kDa, 57 kDa and 44 kDa.
