Provider: Invitrogen Antibodies
Product name: CD25 Monoclonal Antibody (BC96), APC-eFluor™ 780, eBioscience™
Antibody type: Monoclonal
Antigen: Other
Description: Description: The BC96 monoclonal antibody reacts with human CD25, the 55 kDa interleukin-2 receptor alpha chain (IL-2Ralpha). CD25 is expressed by early progenitors of T and B lineage as well as by activated mature T and B lymphocytes. By itself, CD25 binds IL-2 only with low affinity. However, CD25 associates with CD122 (IL-2 receptor beta chain) and CD132 (common gamma chain) to form the high affinity IL-2 receptor. CD25 plays a role in lymphocyte differentiating and activation/proliferation.
Antibody clone number: BC96
Concentration: 5 µL/Test
