Human CD70 is not present on resting lymphocytes. CD70 is expressed after activation on about 20% of T cells and on about 70% of B cells. CD70 is a ligand for CD27 and it is also a member of the tumor necrosis factor gene family (3).

Isotype: Murine IgG1

Immunogen: Human WM-1 (Waldenström’s macroglobulinemia) cell line

Specificity: Antibody BU69 recognizes the CD70 molecule of approximately 30 kd (3).

Functional Application: Antibody BU69 blocks the interaction between CD27 and CD70, and has been shown to inhibit T cell proliferation induced by dendritic cells(5).
