WebPrinciple The Fluorometric Intracellular pH Assay Kit utilizes a proprietary cell-permeable fluorescent indicator, BCFL-AM, for measuring relative intracellular pH changes. BCFL-AM is a superior alternative to the popular ratiometric pH probe, 2′,7′-bis- (2-carboxyethyl)-5 (6)-carboxyfluorescein (BCECF). 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…
