Product Details anti-SIGLEC5 Antibody

Target: SIGLEC5 (Sialic Acid Binding Ig-Like Lectin 5 (SIGLEC5))

Reactivity: Mouse

Host: Rat

Clonality: Monoclonal

Conjugate: This SIGLEC5 antibody is un-conjugated

Application: ELISA, Flow Cytometry (FACS), Immunohistochemistry (Frozen Sections) (IHC (fro)), Immunofluorescence (IF)

Brand: BD Pharmingen™

Characteristics: The E50-2440 antibody reacts with Siglec-F, the sixth siglec protein to be reported in the mouse. Siglecs are the sialic acid-binding immunoglobulin superfamily lectins defined in the human, each of which has a distinctive expression pattern in the hematopoietic system and at least some of which are known to mediate cell-cell interactions. Orthologous proteins of human Siglec-1 (Sialoadhesin or CD169), Siglec-2 (CD22), and Siglec-4 (myelin-associated glycoprotein) have been characterized in the mouse. Human Siglec-3 (CD33) and Siglecs-5 through -10 are encoded by a cluster of closely related genes, and each has two cytoplasmic ITIM (Immunoreceptor Tyrosine-based Inhibitory Motifs). Similarly, mouse Siglec-F is encoded by a gene in a syntenic cluster in the mouse, and the protein has sialic acid-binding activity and an intracytoplasmic ITIM. Its expression pattern differs from those of the human Siglec-3-related proteins in that it is found on immature cells of the myelomonocytic lineage, with reduced expression on mature neutrophils and monocytes, and not on lymphoid cells. It has been proposed that mAb E50-2440 may be used for identification of immature myelomonocytic cells in the mouse. Two-color analysis of Siglec-F expression on bone-marrow myeloid cells. BALB/c bone-marrow leukocytes were stained with either purified rat IgG2a, κ isotype control mAb R35-95 (Cat. No. 553927, left panel) or purified mAb E50-2440 (right panel) in the presence of Mouse Fc Block™ (purified anti-mouse CD16/CD32 mAb 2.4G2, Cat. No. 553141/553142), followed by biotinylated anti-rat IgG2a mAb RG7/1.30 (Cat. No. 553894), then Streptavidin-PE (Cat. No. 554061) and FITC-conjugated anti-mouse CD11b (Integrin αM chain) mAb M1/70 (Cat. No. 557396/553310). Flow cytometry was performed on a FACSCalibur™ .
