General description

BioTracker Orange-NHS Live Cell pH dye is a chemical probe which reversibly fluoresces upon acidic pH. The probe is modified with N-hydroxysuccimide ester (NHS) which forms a covalent bond with primary amines just by mixing. It can be used for labeling proteins, antibodies and other molecules. For example, it can be applied for visualizing endocytosis of target protein on cell membrane by labeling antibodies that binds to the target protein. This probe binds to primary amines just by mixing. Thus it can be used to label antibodies and other proteins which have lysine residues. Its fluorescence intensity increases ~20-fold at an acidic pH.
