Human CD122 (IL-2 R beta) associates with CD25 (IL-2R alpha) to form a high affinity receptor for IL-2 and is expressed on activated T cells, B cells and monocytes (3).  The cytoplasmic domain of CD122 is involved with signal transduction (2).

Isotype: Murine IgG2a kappa

Immunogen: YT-1 acute human leukemia cells

Specificity: Antibody 9A2 is specific for the 75 kd b subunit CD122 of the human high affinity interleukin-2 receptor.

Functional Application: Antibody 9A2 (DU-2) inhibits binding of IL-2 to IL-2R beta (CD122) (1).
