Fig. 5. Interaction of apoA-I with brush border membrane vesicles (BBMV). (A)
125I-apoA-I bound to BBMV; S, washed peripheral membranes; P,
integral membrane fractions. Fractions were separated on a 12% SDS
polyacrylamide gel and the protein detected by autoradiography. (B) Endogenous
content of apoA-I in BBMV and distribution in the peripheral membrane (S) and
integral membrane (P) fractions analysed by western blot.
