  • Product overview

    MMP-3 (Matrix Metalloproteinase-3), also known as stromelysin-1, is involved in wound repair, atherosclerosis and tumors. ab112148 MMP-3 Activity Assay Kit uses a Green Fluorescence probe/fluorescence resonance energy transfer (FRET) peptide as the MMP-3 activity indicator. In the intact FRET peptide, the fluorescence of one half of the probe is quenched by the other part. Upon cleavage into two separate fragments by MMP-3, the green fluorescence is recovered.

    ab112148 is designed to monitor the activity of an MMP-3 enzyme. The peptide sequence used in the kit is more selective for MMP-3 hydrolysis than other MMP enzymes. It can also be used to screen MMP-3 inhibitors when a purified MMP-3 enzyme is used. With excellent fluorescence quantum yield and longer wavelength, the probe shows less interference from autofluorescence of test compounds and cellular components and is much more sensitive than an EDANS/Dabcyl FRET substrate. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format. Its signal can be easily read by a fluorescence microplate reader at Ex/Em = 490/525 nm. The perfect excitation of the green probe at 488 nm makes the assay readily readable with almost all the common fluorescence instruments equipped with Argon laser and FITC filter set.

    ab112148 should be stored Desiccated

  • Tested applicationsSuitable for: Functional Studiesmore details


  • FunctionCan degrade fibronectin, laminin, gelatins of type I, III, IV, and V; collagens III, IV, X, and IX, and cartilage proteoglycans. Activates procollagenase.
  • Sequence similaritiesBelongs to the peptidase M10A family.
    Contains 4 hemopexin-like domains.
  • DomainThe conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.

  • Dose response of MMP-3 enzyme activity.

    The APMA-activated MMP-3 was serially diluted in assay buffer, and then mixed with Green substrate. The fluorescence signal was monitored after one hour using a microplate reader at Ex/Em = 485/525 nm. The reading from all wells was subtracted with the reading from substrate control. As low as 1 ng/well of MMP-3 was detected (n=3). Note: MMP-3 from different sources varies in its endogenous activity.

Thank you for contacting us.

Ab112148is not designed as specific in regards to species. The kit should recognize both species. Substrates can be digested by other MMPs too, but at slower rate than MMP3

Thank you for contacting us. The kit developer has informed me that if activated MMP3 is in the sample, then it will be capable of cleaving the peptide substrate, which creates the signal. So, in theory, APMA is not necessary. I recommend including a p...
