      DescriptionBioTracker CoxFluor Live Cell Dye
      OverviewCyclooxygenase (COX), also known as Prostaglandin-endoperoxide synthase (PTGS), is the key enzyme in prostaglandin biosynthesis. There are two isozymes of cyclooxygenase: a constitutive COX-1 and an inducible COX-2, which differ in their regulation of expression and tissue distribution. COX-2 overexpression is prominent in inflammatory diseases, neurodegenerative disorders, and cancer. Directly monitoring COX-2 activity within its native environment poses an exciting approach to investigate the effect of the local environments on protein activity (1).

      BioTracker CoxFluor Live Cell Dye is an isoform selective activity-based sensor for COX-2. The probe may be used for COX-2 inhibitor screening assays and for monitoring COX-2 activity in live cells by confocal microscopy or flow cytometry. CoxFluor strategically links a natural substrate with a dye precursor to engage both the cyclooxygenase and peroxidase activities of COX-2. This catalyzes the release of resorufin and the natural product, as supported by molecular dynamics and ensemble docking. CoxFluor enabled the detection of oxygen dependent changes in COX-2 activity that are independent of protein expression within live macrophage cells (1).
