Figure 7From: A bovine papillomavirus-1 based vector restores the function of the low-density lipoprotein receptor in the receptor-deficient CHO-ldlA7 cell lineAssessment of the LDL receptor functionality by the internalisation assay. The p3.7LDL-transfected (A) and the native (B) CHOldlA7 cells were incubated with DiI-LDL particles and after fixation viewed by fluorescence microscopy. Signal from the particles (seen as red spots) is visible inside the transfected cells. Some non-transfected cells have labelled particles associated with cell membranes.Back to article page
