This mmp substrate can be used to assess activity of MMP9. This mmp substrate has been used in enzymatic and cell based assays to assess activity of MMP9 since it is specific for this family of metalloproteinases. See our Product Sheets for its substrate specificity profile. Typically, the peptide is dissolved in DMSO to make a stock solution of about 10mM concentration. When used for in vitro assays, the substrate is often used at about 10uM concentration. Remember to keep the DMSO concentration in the final reaction at 1% or below, to avoid DMSO effects on the reaction, and remember to have an equivalent percentage of DMSO in the background wells. For use with the MMPs, the buffer should contain 50 mM Tris, pH 7.5, 150 mM NaCl, 2 mM CaCl2, 5 µM ZnSO4, and 0.01% Brij-35. Excitation and emission wavelengths are 485 and 530 nm respectively.
Greater than 95% as assessed by HPLC and Mass Spectrometry.
1 mg/ml in water with 10% Formic acid
Red lyophilized powder
The peptide powder is shipped at room temperature.
Upon receiving, the peptide should be stored at -70 oC. Avoid repeated freeze-thaw cycles. If dissolved in liquid (such as DMSO), aliquot into separate tubes to minimize the number of freeze-thaw cycles.
Samples are sensitive to light and stable up to 6 months at -70oC.
