ELISA Research
Can ELISA measure the cell supernatant MMP-2 and MMP-9? I read the papers written by others, in addition to measuring the expression of these two indicators, but also to measure the activity, can ELISA measure the activity? What's the difference with gelatin enzymology?

These two kits can be used for the detection of your cell supernatant. However, ELISA detection of cell supernatants is affected by factors such as media components, cell growth, and external drug stimulation conditions, and it is recommended that you conduct a preliminary experiment before the formal experiment.
Gelatin enzyme spectrometry uses the reversible combination of SDS and MMPs in the sample to separate MMP-2 and MMP-9 in the sample, and then restores the activity of both through the bivalent metal ion buffer system. This test method is specifically aimed at the activity detection of MMP-2 and MMP-9. ELISA detects the content (that is, concentration) of the tested substance through the binding reaction of antigen and antibody, that is, captures the MMP-2 and MMP-9 of the sample through the specific antibodies of MMP-2 and MMP-9. The experimental principles of the two are different, and the activity of MMP-2 and MMP-9 cannot be detected by ELISA.
