Description
Phagocytosis in mammals serves as an important first line defense mechanism against invading pathogens. It is also essential for continuous clearance of dying cells, tissue remodeling, and acquisition of nutrients for some cells. Phagocytosis is a specific form of endocytosis initiated by recognition and binding of foreign particles by cell surface receptors, followed by their engulfment, and formation of phagosomes. Maturing phagosomes transform to phagolysosomes which destroy the pathogen through enzymes and toxic peroxides. Zymosan prepared from yeast cell wall (Saccharomyces cerevisiae), and consisting of protein-carbohydrate complexes is frequently used as a pathogen in phagocytosis assays. The Phagocytosis Assay Kit utilizes pre-labeled Zymosan particles as a tool for rapid and accurate detection and quantification of in vitro phagocytosis.
