Protonex(TM) Red 600-Zymosan A Conjugate

The Protonex(TM) Red 600-Zymosan A Conjugate is a ready-to-use reagent designed to study phagocytosis and phagosome acidification in live cells. This conjugate combines Zymosan A particles, a biologically active yeast cell wall component, with Protonex(TM) Red 600, a novel pH-sensitive fluorophore that remains non-fluorescent at neutral pH and becomes highly fluorescent upon entering acidic environments such as maturing phagosomes and phagolysosomes. As a standalone reagent, it enables users to integrate phagocytic detection into their own custom assays. The TRITC-like excitation/emission properties of Protonex(TM) Red 600 make it compatible with a wide range of fluorescence imaging and detection systems. These conjugates can be combined with green fluorescent dyes such as GFP, Calbryte(TM) 520, calcein AM, or FITC-labeled antibodies to enable multiplexed analysis of cell function and viability. It is ideal for immunological research, drug discovery, and mechanistic studies of innate immune function, autophagy, or particle uptake.
