Granulocyte Research

Granulocytes, polymorphonuclear leukocytes with lobulated nuclei and granules in their cytoplasm, can be divided into three subtypes: neutrophils, eosinophils, and basophils. See MoreThese cells are known to secrete toxic granules or histamines, contribute to inflammatory responses, phagocytose pathogens, and regulate innate immune responses. For a convenient source of granulocyte subsets, STEMCELL Technologies offers fresh^1,2 peripheral blood collected from healthy donors. For your convenience we also offer custom frozen primary cell products ¹ to meet your research needs.
