the different effects of 24g2 on b cell activation by intact h delta a/1 and h delta a/1 fab/fc were not a result of differences in the abilities of the intact antibody and its fab/fc fragment to activate b cells , since 24g2 did not interfere with the ability of ams-15 , a igg2a anti-igd mab , to slightly increase b cell sia expression .
