Comparison of the concentration-dependent effects of human and rabbit apoCI on CETP activity as measured from radiolabeled HDL to unlabeled LDL. Transfer activity was determined as the rate of transfer of radiolabeled cholesteryl esters from [3H] cholesteryl ester-HDL to unlabeled LDL in the presence of partially purified human CETP and in the presence of increasing concentrations of either human apoCI (white bars) or rabbit apoCI (gray bars). Data are mean ± SD of three determinations. *P < 0.05 versus homologous control with no apoCI added (black bars; Mann-Whitney).
