Scientific Data Images for Human Siglec-16 Antibody

Detection of Siglec-16 antibody in HEK293 Human Cell Line Transfected with Human Siglec-16 and eGFP antibody by Flow Cytometry

Detection of Siglec-16 in HEK293 Human Cell Line Transfected with Human Siglec-16 and eGFP by Flow Cytometry

HEK293 human embryonic kidney cell line transfected with (A) human Siglec-16 or (B) human Siglec-11, and eGFP was stained with Mouse Anti-Human Siglec-16 Monoclonal Antibody (Catalog # MAB68191) followed by APC-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). Quadrant markers were set based on control antibody staining (Catalog # MAB0041) .View our protocol for Staining Membrane-associated Proteins.

Detection of Siglec-16 in CHO cells transfected with human Siglec-16 or irrelevant transfectant cells by Flow Cytometry.

CHO cells transfected with human Siglec-16 (filled histogram) or irrelevant transfectant cells (open histogram) were stained with Mouse Anti-Human Siglec-16 Monoclonal Antibody (Catalog # MAB68191), followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed and permeabilized with Flow Cytometry Fixation Buffer (Catalog # FC004). View our protocol for Staining Intracellular Molecules.

Background: Siglec-16

Siglec-16 (Sialic acid-binding Ig-like lectin 16) is a 58-60 kDa member of the CD33-related SIGLEC family of proteins. It is expressed on macrophages and microglia, and based on Siglec-11, likely binds to an alpha2,8-linked sialic acid motif. Although Siglec-16 is assumed to have arisen from a Siglec-11 gene duplication and conversion, it is not an inhibitory receptor but an activating one, and possesses a transmembrane (TM) Lys that interacts with DAP12. Mature human Siglec-16 is a 465 amino acid (aa) type I TM glycoprotein. It contains a 418 aa extracellular region (aa 17-434) that shows one V-type (aa 19-122) plus three C2-type (aa 147-424) Ig‑like domains, and a short 26 aa cytoplasmic tail. Notably, Siglec-16 exists as a pseudogene in approximately 50% of surveyed population. There is no Siglec-16 counterpart in either rodent or distant primate such as Rhesus monkey. The extracellular domain (ECD) of human Siglec-16 shares 94% aa identity with the ECD of human Siglec-11.
