Biological Activity
pH Receptor Probe technology utilizes the general ability of GPCRs to be internalized into the endosomal pathway of a cell in response to agonist ligands. The pH Receptor Probe dye is fluorescent in acidic environments, but nonfluorescent at neutral pH. When pH Receptor Probe is bound to a receptor on the extracellular surface of the cell, it is essentially nonfluorescent. On internalization into a cell, it displays a significant increase in fluorescence[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
