Fig. 9. LDLRH190Y can recycle constitutively and mediates endocytic uptake of LDL in vitro. The ldlA(LDLRH190Y) transfectants were incubated with OG-LDL for 15 minutes (A), after which the receptor was visualized with anti-LDLR antibody C7 (B) following fixation. The arrows indicate the ERC in transfected cells (B). Scale bar, 10 µm (B).
