Protocol Available protocols: Western Blotting, Immunoprecipitation Specificity / Sensitivity Siglec-7 (F4O1S) Rabbit Monoclonal Antibody recognizes endogenous levels of total Siglec-7 protein. This antibody detects an 18 kDa band of unknown origin in some cell lines. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Met395 of human Siglec-7 protein. Background Sialic acid-binding Ig-like lectin 7 (Siglec-7), also known as AIRM1, is a member of the CD33-related Siglec family, a subset of the immunoglobulin superfamily of cell surface proteins (1-3). Siglec-7 is found in human immune cells, such as natural killer (NK) cells, monocytes, and neutrophils (1,2). Siglec-7 acts as an immune inhibitory receptor via its intracellular tyrosine-based inhibitory motif (ITIM) (1-5). Downregulation of cell surface Siglec-7 is an early marker of NK cell dysfunction, which can be associated with chronic viral infection or impaired anti-tumor activity (4).
