Description
The sensitive quantitative measurement of functionally active human PAI-1 in plasma samples is easily performed with this 96 well strip format ELISA kit. The PAI-1 concentration of normal platelet-free plasma is 21 ng/ml, platelet-rich plasma is 283 ng/ml and serum is 270 ng/ml. 1 PAI-1 unit = 1.34 ng. Latent or complexed PAI-1 will not bind to the plate and will not be detected by the assay. Validated in citrate, EDTA, and heparin plasma. Vitronectin does not interfere with the detection of active PAI-1. This kit does not cross react with mouse PAI-1. The Human PAI-1 standard provided in this kit is calibrated against the WHO International Standard for Human PAI-1 (NIBSC Code 92/654)
