General description

The CHEMICON PAI Activity Assay Kit provides a quick, efficient and sensitive system for evaluation of inhibition of uPA activity by PAI and for screening of uPA inhibitors. The assay is colorimetric and does not require radioactivity or fluorescence equipment. The assay is sensitive over an inhibition range of 0.05-50 units of uPA activity.

The CHEMICON PAI Activity Assay Kit utilizes a chromogenic substrate, which is cleaved by active uPA, detectable by its Optical Density at 405nm (OD405). Addition of PAI sample blocks the cleavage of substrate by uPA.

The CHEMICON PAI Assay Kit is ideal for measurement of PAI inhibitory activity toward uPA in purified preparations and cell culture, as well as in serum where pathological conditions such as sepsis exist. The assay is also useful for screening inhibitors of uPA.

Each CHEMICON PAI Activity Assay Kit contains sufficient reagents for the evaluation of 96 samples, including uPA standard from human urine and E.Coli-expressed recombinant protein corresponding to amino acids 24 to 427 of human PAI-1 (mature form) as positive control. PAI-1 positive control contains a mixture of the active and latent forms, with >45% of active form. Duplicate or triplicate samples are suggested.
