Description

The 24-31 monoclonal antibody reacts with human CD154, a 39 kDa transmembrane glycoprotein also known as gp39 and CD40 ligand (CD40L). CD154 is a member of the TNF superfamily and is expressed transiently by activated T cells. Through its binding to CD40 on antigen presenting cells including B cells, monocytes/macrophages and dendritic cells, CD154 serves a crucial function in T-APC cognate interaction. CD154 interaction with CD40 transduces signals for T-dependent B-cell activation and induces B cell cycle entry. 24-31 cross-reacts with the Cynomogus monkey CD154.

Applications Reported

For research use only, not for diagnostic or therapeutic use. 24-31 has been reported for use in flow cytometric analysis.

Applications Tested

The 24-31 antibody has been pretitrated and tested by flow cytometric analysis of resting and activated human PBMC and can be used at 20 µl (0.5 μg) per test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
