Reducing SDS-PAGE analysis showing quantitative cleavage in the hinge region (lane 4, red asterisk) of C-terminally truncated wild-type (WT) IgA2Δ3 (lane 3) after overnight incubation with IgAse1–4 (lane 1). In contrast, mutants T84R/S94Y (lanes 5 and 6) and D96R/S94Y/T98W (lanes 7 and 8) are not cleaved. Lane 2 depicts the BlueStar Plus Molecular Weight ladder.
