CD23 antibodies, mouse

CD23 antibodies, mouse

Clone: B3B4 | Dilution: 1:10
The monoclonal antibody B3B4 recognizes CD23, also known as low affinity IgE Fc receptor (FcεRII), a type II integral membrane glycoprotein. CD23 is expressed on mature B cells, but not on CD5
B-1 cells, activated B cells, follicular dendritic cells of immunized mice and on a subset of splenic dendritic cells. Clone B3B4 is reported to block IgE binding to FcεRII.

Alternative names

Fcer2a, FCE2, FCER2, Ly-42
