... that constitutively expressed apoE–GFP (green fluorescent protein). In addition, we used biotinylated apoE (in a lipid-free state and as a lipidated discoidal complex) to track the uptake and potential nuclear targeting of exogenous apoE. Our results indicate that a small proportion of apoE–GFP is detected...
