Coupled enzymatic assay
Continuous assays are most convenient, with one assay giving the rate of reaction with no further work necessary. There are many different types of continuous assays. In spectrophotometric assays, you follow the course of the reaction by measuring a change in how much light the assay solution absorbs. If this light is in the vis… WebJul 11, 2007 · At the time of development of our assay, we were aware of a cell-based microplate colorimetric assay (Promega) that measured LDH activity as an indicator of cell death. However, since this was a coupled enzyme assay, we chose to proceed in a different direction so as to keep the assay simpler for ourselves and for the students.
