The antibody was purified by affinity chromatography, and conjugated with PE under optimal conditions. The solution is free of unconjugated PE and unconjugated antibody.
CD226 (DNAM-1) is constitutively expressed on native CD8+ cells and on CD4+ T cells,macrophages and NK cells.This antibody (10E5) was reported to bind about 40 % of inactivated CD4+ cells and binds only to differentiated Th1 cells, but not to Th2 or Th0 cells.It is also reported to suppress antigen-specific T cell expansion and EAE(experimental allergic encephalitis) mediated by Th1 cells.
