Fibronectin-purified Human Monocytes

mAb 24 (also known as 24 or m24) specifically recognizes a divalent cation-dependent epitope expressed by active human Integrin β2 which is also known as CD18. Integrin β2 is an ~95 kDa type I transmembrane glycoprotein that is encoded by ITGB2 (integrin subunit beta 2). Integrin β2 (CD18) noncovalently associates with other integrin α chains to form αLβ2 (CD11a/CD18; also known as, LFA-1), αMβ2 (CD11b/CD18; Mac-1, CR3), αXβ2 (CD11c/CD18; p150,95; CR4) and αDβ2 (CD11d/CD18) heterodimers. These integrins are variably expressed on lymphocytes, NK cells, neutrophils, eosinophils, basophils, monocytes, macrophages, Langerhans cells, and dendritic cells (DCs). These leucocyte integrins bind to various ligands and mediate cellular adhesion and signaling responses that regulate cellular activation, effector function, and migration. mAb 24 binds to the extended/open, high-affinity ligand-binding conformation of active Integrin β2 (CD18). mAb 24 can be used as a reporter antibody for the activated status of Integrin β2-containing receptors expressed by leucocytes in response to various stimuli in the presence of Mg2+ or Mn2+.
