thus , when bovine lymph node lymphocytes are stimulated either with concanavalin a ( con a ) or with a combination of phytohemagglutinin ( pha ) and the phorbol ester 12-o-tetradecanoylphorbol-13-acetate ( tpa ) , the concentration of otes in the lymphocytes decreases within 3 h by a factor of approximately two .
