L11 fails to block binding of lymphocytes to MAdCAM-1 or ICAM-1. (A) antiβ7 mAb cocktail containing FIB504, FIB30, and DATK32 (26) blocks binding of MLN lymphocytes to purified MAdCAM-1 and (B) anti–LFA-1 mAb blocks binding of Mn2+treated MLN lymphocytes to purified ICAM-1; however, L11 fails to block binding to either ligand.
