产品信息 Form Liquid Formulation In 150 mM NaCl, 50 mM sodium phosphate buffer, 1 mM EDTA, pH 6.6. Avoid freeze/thaw 是的 Biological activity ≥90% by uPA assay Purity ≥98% by SDS-PAGE Storage ≤ -70°C PAI-1 is the primary inhibitor of both tissue plasminogen activator (tPA) and urokinase (uPA). PAI-1 can exist either in an active inhibitory conformation or in an inactive or latent conformation. This highly purified preparation has not been exposed to denaturing conditions and has been chromatographically purified of latent material. PAI-1 is a marker for acute myocardial infarction and several thrombolytic disorders. Protects platelets against the inhibitory effects of plasma. Reported to be an important prognostic factor in breast cancer patients. PAI-1 is highly stable when stored at or below pH 6.6.
