ICC 1/250 - 1/500.
  • Application notes
    Is unsuitable for Flow Cyt,IHC-P or IP.
  • Target

    • Function

      CD2 interacts with lymphocyte function-associated antigen (LFA-3) and CD48/BCM1 to mediate adhesion between T-cells and other cell types. CD2 is implicated in the triggering of T-cells, the cytoplasmic domain is implicated in the signaling function.
    • Sequence similarities

      Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
      Contains 1 Ig-like V-type (immunoglobulin-like) domain.
