QuickZyme Human MMP-9 Activity Assay Kit 96 Assays 96-well plate format immunoassay for active or total MMP-9 The QuickZyme Human MMP-9 Activity Assay is an enzyme activity immunoassay that enables you to specifically measure endogenous active MMP-9 OR total active MMP-9 (following activation of pro-MMP-9 on the plate with APMA) It can be used for the measurement of MMP-9 activity in various biological samples such as conditioned cell culture medium serum plasma urine synovial fluid and tissue homogenates This 96-well plate format assay is based on the QuickZyme technology using a modified pro-enzyme as a substrate which upon activation is able to release color from a chromogenic peptide substrate This multiplication step provides a unique assay sensitivity Assay Range 0 5 - 16 ng/ml (1 h incubation) 0 01-1 ng/ml (4 h incubation) Sensitivity 0 005 ng/ml Synonyms Matrix metalloproteinase-9 MMP9 92 kDa gelatinase 92 kDa type IV collagenase Gelatinase B GELB
