Neutrophil

The Ly-6G/-6C locus encodes a family of Ly-6 proteins. Ly-6 antigens have a molecular weight between 15,000-18,000. Ly6G is together with Ly6c a component of the myeloid differentiation antigen Gr-1. Ly6G, a GPI-anchored protein, is a good marker of peripheral neutrophils. Although predominantly present on neutrophils, it is also expressed on a subset of eosinophils, differentiating premonocytes and plasmacytoid dendritic cells. Ly6C is a monocyte/macrophage and endothelial cell differentiation antigen regulated by interferon gamma. It may play a role in the development and maturation of lymphocytes. It is expressed on bone marrow cells, monocytes/macrophages, neutrophils, endothelial cells and T cell subsets. Expression of Gr-1 in bone marrow correlates with granulocyte differentiation and maturation. The physiological role of Ly6G alone remains unclear. N2254 has been successfully used to stain polymorphonuclear (PMN) cells and monocytes for fluorescent activated cell sorting and in frozen and paraffin sections. Treatment with antibodies in vivo leads to neutropenia and has an inhibitory effect on local immune responses. It has been shown to be useful for depletion of neutrophils in mice, depleting neutrophils as soon as 6hr after injection and up to 6 days.\n\nApplications: \nSuitable for use in Flow Cytometry, ELISA, Functional Studies and Immunohistochemistry.
