Description

The Tu1 monoclonal antibody reacts with human CD23, a 45 kDa type II transmembrane glycoprotein. CD23 is expressed on mature B cells, mantle zone B cells, follicular dendritic cells and at low levels on T, NK, langerhans cells and platelets. Expression of CD23 is upregulated upon B cell activation, and soluble forms of the antigen have been reported to be biologically active. CD23 is a low affinity receptor for IgE and is thought to play a role in the regulation of IgE response and B cell activation. CD21, and the α subunit of CD11b and CD11c bind to CD23.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The Tu1 antibody can be used in flow cytometric analysis.

Applications Tested

The Tu1 antibody has been pre-titrated and tested by flow cytometric analysis of human peripheral blood leukocytes and can be used at 10 µl per million cells (100 µl blood).
