PLAP and hTfR patching depends on membrane cholesterol. BHK cells transiently expressing PLAP (A) and hTfR (B) were depleted of membrane cholesterol using cyclodextrin extraction. PLAP and hTfR were cross-linked using anti-PLAP and anti-hTfR mAb, respectively, followed by rhodamine-coupled secondary antibodies. Patching of PLAP as well as hTfR is inhibited under these conditions. Bar, 5 μm.
