(A) Demonstration of the LDL receptor on up-regulated G4 cell using anti-LDL receptor antibody (green fluorescent staining). The signal was very weak in ≈30% of G4 cells without up-regulation of the LDL receptor (not shown). (B) Demonstration of the uptake of 5 μg of DiI-LDL by G4 cells that have up-regulated LDL receptors as in A. (C) Inhibition of 5 μg of DiI-LDL endocytosis by 30× excess of unlabeled LDL. (D) Same field as C by phase contrast microscopy. Original magnification, ×500.
