Flow cytometry analysis of MAL expression in peripheral blood lymphocyte subsets. After permeabilization with 0.1% saponin PBS, peripheral blood lymphocytes were double-stained with MAL antibody after permeabilization with 0.1% saponin PBS and CD4 or CD19 antibody. Analysis was restricted to elements in the lymphocyte gate. A, MAL is expressed in 77% of CD4+ lymphocytes. B, MAL is not expressed in normal peripheral B lymphocytes.
