01MT00241

Clone REA378 recognizes the human CD11a antigen, a single-pass type I membrane protein also known as integrin α-L (ITGAL). Integrins are heterodimeric adhesion molecules comprised of α- and β-subunits that participate in immune cell interactions as well as in immune cell-extracellular matrix interactions. CD11a combines with CD18 (ITGB2) to form the integrin lymphocyte function-associated antigen-1 (LFA-1), which is expressed on all leukocytes. LFA-1 is a receptor for CD54 (ICAM-1), CD102 (ICAM-2), CD50 (ICAM-3), and CD242 (ICAM-4). It is involved in a variety of immune phenomena including leu
