Quick Overview for Integrin beta 2 antibody (Activation Site) (ABIN111897)

Target: Integrin beta 2 (ITGB2)

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This Integrin beta 2 antibody is un-conjugated

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

Clone: MEM-148

Product Details anti-Integrin beta 2 Antibody

Binding Specificity: Activation Site

Specificity: MEM-148 recognizes the β2 integrin subunit that pairs with each of four distinctive CD11 α subunits to form the CD11/CD18 integrin heterodimers. MEM-148 potently promoted adhesion of LFA-1/K562 transfectants and neutrophils to their respective immobilized ligands, suggesting it to be one of the select class of monoclonal antibodies which can act on the ectodomain of the integrin to induce adhesion. Expression of the epitope recognized by MEM-148 is minimal on β2 integrin transfectants, T cells, eosinophils, monocytes and neutrophils.

Purification: Purified

Isotype: IgG1

Target Details for Integrin beta 2

Target: Integrin beta 2 (ITGB2)

Alternative Name: CD18 / ITGB2

Background: CD18 is an integrin. Integrins are integral cell surface proteins composed of an alpha chain and a beta chain. A given chain may combine with multiple partners resulting in different integrins. For example, beta 2 combines with the alpha L chain to form the integrin LFA1, and combines with the alpha M chain to form the integrin Mac1. Integrins are known to participate in cell adhesion as well as cell surface mediated signalling. CD18 is expressed by most leucocytes. Defects in the CD18 gene result in leukocyte adhesion deficiency.Synonyms: 95 subunit beta, Cell surface adhesion glycoproteins LFA-1/CR3/p150, Complement receptor C3 subunit beta, Integrin beta-2, MFI7
