For quantitative determination of plasmin enzyme activity in biological samples. Key Features: Safe and sensitive. Non-radioactive assay. Use as little as 10 µ L samples. Linear detection range in 96-well plate: 0.35 to 56.5 U/L activity. Fast and convenient. The procedure involves addition of a single working reagent and incubation for 30 min. High-throughput. Homogeneous “mix-incubate-measure” type assay. Can be readily automated to assay thousands of samples per day. Method: OD405nm. Samples: Serum and other biological samples.
