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™ BV786 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 786-nm. BD Horizon BV786 can be excited by the violet laser and detected in a filter used to detect Cy™7-like dyes (eg, 780/60-nm filter).
