Popis: The stabilities toward thermal and chemical denaturation of three recombinant isoforms of human apolipoprotein E (r-apoE2, r-apoE3 and r-apoE4), human plasma apoE3, the recombinant amino-terminal (NT) and the carboxyl-terminal (CT) domains of plasma apoE3 at pH 7 were studied using near and far ultraviolet circular dichroism (UV CD), fluorescence and size-exclusion chromatography. By far UV CD, thermal unfolding was irreversible for the intact apoE isoforms and consisted of a single transition. The r-apoE3 was found to be less stable as compared to the plasma protein and the stability of recombinant isoforms was r-apoE4
