General description
Cyclooxygenase (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.
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.
Spectral Properties
Absorbance: 540 nm
Emission: 590 nm
