Fig. 7From: Alpha-1-antitrypsin interacts with gp41 to block HIV-1 entry into CD4+ T lymphocytesSPR assay of AAT/C and gp41 interaction. gp120 (6.25–200 μg/mL) and gp41 (18.75–600 μg/mL) were analyzed for binding to immobilized AAT, C or ΔAAT. Representative Sensorgrams were displayed and the amount of bound gp120 or gp41 was shown over time. Binding curves revealing saturable kinetics for the interaction were also plottedBack to article page
