> MR1, an antibody to murine CD40L (which is available from Pharmingen), does
>not cross-react with human CD40L. Its detection on murine cells requires
>purification of the CD4 cells (apparently B cells can downregulate CD40L
>expressed on activated T cells), followed by activation with anti-CD3 or
>PMA/ionomycin. For information about its detection and expression, look up:
> The regulation of expression of gp39, the CD40 ligand, on normal and cloned
>CD4-positive T cells.
