New pH-sensitive pHrodo™ Red dye conjugates give faster and more accurate results than any other phagocytosis assay. pHrodo™ Red dye conjugates are non-fluorescent outside the cell, but fluoresce brightly red in phagosomes. Get faster staining and more accurate results—without the need for wash steps or quencher dye.

• Specific detection of phagocytosis and endocytosis
• Reduced signal variability and improved timing in sensitive experiments
• Multiplex with green dyes such as GFP, Fluo-4, or calcein

The fluorescence of the novel pHrodo™ Red dye dramatically increases as pH decreases from neutral to acidic, making it an ideal tool to study phagocytosis and its regulation by drugs and/or environmental factors. The lack of fluorescence outside the cell eliminates the need for wash steps and quencher dyes.

Use the ready-made pHrodo™ Red Zymosan BioParticles™ Conjugate in imaging or flow applications, or pHrodo™ Red SE, the activated succinimidyl ester, for labeling microorganisms or proteins of your choice.

In addition, pHrodo™ dye is also available in green color, with E. coli, zymosan, S. aureus, and dextran 10,000 conjugates.
