Product details:
Phagocytosis Assay Kit ab211156 uses a Zymosan substrate to provide a robust system for screening TLR ligands, phagocytosis activators or inhibitors.
Colorimetric phagocytosis assay principle
The phagocytosis assay uses pre-labeled Zymosan particles as a pathogen to trigger phagocytosis. The label on the engulfed Zymosan particles then reacts with a substrate to produce a colorimetric signal that can be detected by absorbance at 405 nm.
External particles are blocked before the reaction with a blocking reagent, ensuring the signal is directly proportional to the amount of internalized particles.
This format provides a quantitative, high-throughput method to accurately measure phagocytosis, and avoids subjective manual counting of Zymosan particles inside cells.
Phagocytosis assay protocol summary
- add Zymosan substrate to cell cultures and incubate for 15 min to 2 hrs
- remove culture medium, and wash cells
- add fixation solution and incubate for 5 min and then wash cells
- add blocking reagent and incubate for 60 min and then wash cells
- add permeabilization solution and incubate for 5 min and then wash cells
- add detection reagent and incubate for 60 min and then wash cells
- add detection buffer and incubate for 10 min
- add substrate and incubate for 5-20 min
- add stop solution and analyze with plate reader

Other notes
In mammals, phagocytosis by phagocytes (e.g., macrophages, dendritic cells, and neutrophils) is essential for a variety of biological events. Phagocytosis comprises a series of events, starting with the binding and recognition of particles by cell surface receptors, followed by the formation of actin-rich membrane extensions around the particle.
Zymosan (Saccharomyces cerevisiae) is prepared from yeast cell wall and consists of protein-carbohydrate complexes. Zymosan is a commonly used pathogen in phagocytosis assays.
