CD154 Antibody, anti-human, APC

01MT17931

The antibody specifically recognizes the human 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. The antibody has been shown to block the activation of antigen-presenting cells by T helper cells in vitro. Because of its transient expression within hours after activation, CD154 can be used as a marker for activated antigen-specific CD4+ T cells. The addition
