Fig. 7. Fate of other GPI₁ reporters. Bloodstream trypanosome cell lines expressing BiPNHP (A,B) or p67HP (C,D) in the absence (-) or presence (+) of FMK024, were pulse (15 minutes)-chase radiolabeled. Cell and media fractions were immunoprecipitated with specific anti-BiP (A,B) or anti-HA (C,D). All samples were analyzed by SDS-PAGE and phosphorimaging. Mobilities of precursor (P) and mature (M) forms of the BiPNHP and p67HP reporters, and of endogenous full-length BiP are indicated on the left of A-D.
