Sialoadhesin/CD169 antibody

Catalog No. ABIN111838

Product Details anti-Sialoadhesin/CD169 Antibody

Target: Sialoadhesin/CD169 (SIGLEC1) (Sialic Acid Binding Ig-Like Lectin 1, Sialoadhesin (SIGLEC1))

Reactivity: Rat

Host: Mouse

Clonality: Monoclonal

Conjugate: This Sialoadhesin/CD169 antibody is un-conjugated

Application: Flow Cytometry (FACS), Immunoprecipitation (IP), Immunohistochemistry (Frozen Sections) (IHC (fro))

Specificity: This antibody recognises the CD169 cell surface antigen. CD169 is a 185 kDa molecule expressed by macrophages, predominately confined to lymphoid organs only. Monocytes and granulocytes are negative. No other cell types are positive. The most conspicious property of ED3 is it stains marginal zone macrophages and marginal metallophils in the spleen very strongly. Furthermore, macrophages in (auto-immune) diseased tissues express the ED3 antigen. In healthy tissue no expression occurs. CD169 is a receptor for glycoconjugates containing sialic acid.

Purification: Affinity Chromatography on Protein G.

Immunogen: Rat Spleen cell homogenate. Spleen cells from immunised BALB/c mice were fused with cells of the SP2/0-Ag 14 mouse myeloma cell line.

Clone: ED3

Isotype: IgG2a

Background: Two families of mammalian lectin like adhesion molecules have been shown to bind glycoconjugate ligands in a sialic acid dependent manner: the selectins and the sialoadhesins. The sialoadhesin family has 4 members: CD22, a B cell specific marker, myelin associated glycoprotein (MAG), which is expressed on oligodendrocytes and Schwann cells, CD33, a myeloid differentiation antigen, and sialoadhesin, which is expressed only by a subpopulation of tissue macrophages. Involved in cell-cell interactions, sialoadhesin is structurally related to the 3 other listed members of the sialoadhesin family. CD169 is a sialic acid binding site of sialoadhesin. CD169 is a macrophage receptor expressed on stromal macrophages in many tissues, particularly found in lymph nodes, bone marrow and spleen.Synonyms: Sialic acid-binding Ig-like lectin 1, Sialoadhesin, Siglec-1
