CD11b/Mac-1 Mouse anti-Human, BUV395, Clone: ICRF44 (also known as 44), BD

The ICRF44 monoclonal antibody specifically binds to CD11b, the 165-kDa adhesion glycoprotein that associates with the 95-kDa integrin β 2 (CD18) to form the CD11b/CD18 complex, also known as Mac-1 or CR3. CD11b is expressed on activated lymphocytes, monocytes, granulocytes, and a subset of NK cells. CD11b functions in cell-cell and cell-substrate interactions and is a receptor for iC3b, CD54 (ICAM-1), CD102 (ICAM-2) and CD50 (ICAM-3). This antibody significantly inhibits polymorphonuclear leukocyte aggregation in response to fMLP.

The antibody was conjugated to BD Horizon™ BUV395 which has been exclusively developed by BD Biosciences as an optimal dye for use on a 355nm laser equipped instrument. With an Ex Max at 348nm and an Em Max at 395nm, this dye has virtually no spillover into any other detector. BD Horizon™ BUV395 can be excited with a 355nm laser and detected with a 379/28 filter.
