Anti-SIGLEC5 antibody produced in rabbit

产品说明

一般描述

SIGLEC5 (sialic acid binding Ig like lectin 5) is a surface receptor, which binds to carbohydrates, and is expressed on neutrophils, monocytes, and B-cells of human myeloid and lymphoid cell lineage. It belongs to the Siglec protein family. It is commonly known as CD170.

免疫原

Sialic acid-binding Ig-like lectin 5 precursor recombinant protein epitope signature tag (PrEST)

应用

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

生化/生理作用

SIGLEC5 (sialic acid binding Ig like lectin 5) is involved in immunosppressiveness by interacting in a hemophilic manner. It interacts with acute phase protein a₁-acid glycoprotein, group B streptococcal cell-wall-anchored β protein and the sialylated lipopolysaccharide of Neisseria meningitides. This protein recruits the phosphatases SHP-1 and SHP-2 to its intracellular ITIMs (immunoreceptor tyrosine-based inhibitory motif), which prevents the activation of kinase-dependent activation cascades. Unmasking of this protein is essential for the proinflammatory effect of S. pneumoniae desialylation of the leukocyte cell surface. Interaction of Group B Streptococcus (GBS) β protein with SIGLEC5 results in suppression of human leukocytes phagocytosis function, oxidative burst, and extracellular trap production. This leads to increased bacterial survival.

特点和优势

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
