Used in biomedical research to quantify rat tissue plasminogen activator (t-PA) levels in biological samples such as plasma, serum, and tissue homogenates. This ELISA kit enables researchers to study fibrinolysis, the body's natural process of breaking down blood clots, in experimental models. It is particularly valuable in cardiovascular research, including studies on thrombosis, stroke, and the effects of therapeutic agents on clot dissolution. The assay supports high sensitivity and specificity, allowing accurate measurement of t-PA antigen levels in rat samples, which helps in understanding disease mechanisms and evaluating drug efficacy in preclinical studies.
