CD154 Antibody, anti-mouse, PE, REAfinity™

01MT06547

Clone REA785 specifically recognizes the mouse CD154 antigen, a 39 kDa transmembrane glycoprotein also known as CD40L, gp39, T-BAM, TRAP, or Ly-62. CD154 is transiently up-regulated on activated CD4+ T cells and plays an important role as a costimulatory molecule in T cell/antigen–presenting cell interactions through ligation of CD40. Due to its transient expression within hours after activation, CD154 can be used as a marker for activated antigen-specific CD4+ T cells. Adding a CD40-blocking antibody during the stimulation of cell suspensions prevents the down-regulation of CD154. Blocking of
