Expression of human CD25 (the alpha subunit of the IL-2 receptor complex) is dramatically upregulated on activated T cells, B cells, NK cells and macrophages (3). Antibodies to CD25 are being studied for potential use as an immunodirected therapy to selectively attack (kill) CD25 expressing cells (4).

Isotype: Murine IgG2a

Immunogen: Stimulated PBMC

Specificity: Antibody 7G7B6 recognizes epitope B of the IL-2 alpha receptor of about 55 kd (1,6).

Functional Application: Antibody 7G7B6 does not block IL-2 binding to its receptor (1).
