The 3C4 (mIC2/4) monoclonal antibody specifically binds to the mouse ICAM-2 (CD102) cell surface glycoprotein, a ligand for LFA-1. CD102 is constitutively expressed on endothelial cells, T and B lymphocytes, and alveolar walls. It is also expressed on a variety of leukocyte cell lines. CD102 does not appear to be involved in the development of hematopoietic cells. In a model for allergic asthma, endothelial CD102 mediates the transmigration of eosinophils (but not lymphocytes, monocytes, or macrophages) into the airway lumen. The 3C4 (mIC2/4) antibody blocks interactions between ICAM-2 and LFA-1.
The antibody was conjugated to BD Horizon BUV615 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome with an Ex Max near 350 nm and an Em Max near 615 nm. BD Horizon Brilliant BUV615 can be excited by the ultraviolet laser (355 nm) and detected with a 610/20 filter and a 595 nm LP. Due to the excitation of the acceptor dye by the blue/yellow-green laser line, there may be significant spillover into channels detecting PE-CF594 like emissions (eg, 610/20-nm filter).
