一般描述
Biotrak™ MMP-9, Activity Assay System Companies provides a simple, specific and precise quantitative determination of active or pro MMP-9 in tissue culture supernatants, serum, plasma, synovial fluid and tissue homogenates. Active MMP-9 may be measured in the range 0.5 to 16 ng/mL for normal endogenous MMP-9 levels. A longer incubation protocol enables an assay range of 0.125 to 4 ng/mL for lower endogenous MMP-9 levels. The assay uses the pro form of a detection enzyme that can be activated by captured active MMP-9, into an active detection enzyme, through a single proteolytic event. The natural activation sequence in the pro detection enzyme has been replaced using protein engineering, with an artificial sequence recognized by specific matrix metalloproteinases.
MMP activated detection enzyme can then be measured using a specific chromogenic peptide substrate. Standards and samples are incubated in microtitre wells precoated with anti-MMP-9 antibody. Any MMP-9 present will be bound to the wells, other components of the sample being removed by washing and aspiration. Either the endogenous levels of free active MMP-9, or the total levels of free MMP-9 in a sample, can be detected. In order to measure the total MMP-9 content, any bound MMP-9 in its pro form is activated using p-Aminophenylmercuric Acetate (APMA). The standard is pro MMP-9 which is activated in parallel for both types of sample. Active MMP- 9 is detected through activation of the modified pro detection enzyme and the subsequent cleavage of its chromogenic peptide substrate. The resultant colour is read at 405 nm in a microplate spectrophotometer. The concentration of active MMP-9 in a sample is determined by interpolation from a standard curve. Each pack contains reagents for 96 determinations. This allows the construction of a standard curve plus the measurement of 42 samples in duplicate. The Biotrak™ MMP-9 activity assay system has been specifically designed for research purposes.
