From
Recombinant Antibody
Specificity
This antibody is specific for human CD23. CD23 is a low-affinity receptor for immunoglobulin E (IgE) and CR2/CD21. It has essential roles in the regulation of IgE production and in the differentiation of B- cells.
Alternative Names
Low affinity immunoglobulin epsilon Fc receptor; FCER2; BLAST-2; C- type lectin domain family 4 member J; Fc-epsilon-RII; Immunoglobulin E-binding factor; Lymphocyte IgE receptor

Immunogen
The mouse version of this antibody was raised by immunizing a BALB/c mouse with Daudi (human Burkitt's lymphoma cell-line).
Application Notes
To examine B1 and B2 cells for their ability to be rendered unresponsive by using an anti-lg tolerance protocol that is independent of receptor specificity, flow cytometry was performed on mouse splenic B cell suspensions using the mouse version of this antibody (Liou et al, 1995; pmid:7759864).

Note on publication
Spleen cells from transgenic mice, whose rearranged Ig receptors reflect the repertoires of B1 (CD5+ and "sister" B cells) or normal B2 cells, were examined for their ability to be rendered unresponsive. By using an anti-Ig tolerance protocol that is independent of receptor specificity, we previously reported that peritoneal B cells, containing primarily CD5+ and "sister" B cells, were not susceptible to unresponsiveness. Herein, we show that splenic B cells from two separate transgenic mouse lines, each expressing a B1-type receptor, are resistant to tolerance induction in vitro.
