CD11b is a 165 kD molecule also know as the alpha-M integrin, MAC-1 and CR3. This molecule is expressed as a heterodimer in association with the beta-2 integrin and is found on monocytes, granulocytes, NK cells and some peripheral blood lymphocytes. ICR44 significantly blocks homotypic PNM aggregation on response to FMLP (3,4).Synonyms: CD11 antigen-like family member B, CR-3 alpha chain, CR3A, Cell surface glycoprotein MAC-1 subunit alpha, ITGAM, Integrin alpha-M, Leukocyte adhesion receptor MO1, MAC1, Neutrophil adherence receptor
