  • Title: Effects of La3+ on lipid fluidity and structural transitions in human erythrocyte membranes.
    Author: Li XM, Ni JZ, Chen JW, Hwang F.
    Journal: Biochem Mol Biol Int; 1998 Jun; 45(2):323-30. PubMed ID: 9678253.
    Abstract:
    The effects of La3+ on the structure and function of human erythrocyte membranes were investigated by fluorescence polarization, spin-labeled electron spin resonance (ESR) and differential scanning calorimetry (DSC). The results showed that increasing concentrations of La3+ inhibited (Na(+) + K+)-ATPase and Mg(2+)-ATPase activities. La3+ lowered the lipid fluidity of erythrocyte membranes and induced structural transitions in erythrocyte membranes.
