Anti-IL-2RB (CD122) [5H4] Antibody

This rat IgG2a monoclonal antibody was raised against rat YB2/0 cell line expressing truncated IL-2Rβ and is specific for mouse Interleukin 2 receptor beta chain (IL-2Rβ).


  • Reacts with mouse IL-2Rβ

Recombinant versions available at our sister company, Absolute Antibody:

The 5H4 antibody reacts with mouse CD122, the 90-110 kDa interleukin-2 receptor beta chain. CD122 is expressed by NK cells and some T cells in the periphery and is upregulated by activation. CD122 associates with CD25 and CD132 (common gamma chain) to form the high affinity IL-2 receptor. Binding of IL-2 to CD122 is not inhibited by the 5H4 antibody.
