Differential scanning calorimetry of chromaffin granule membranes.
Differential scanning calorimetry thermograms of native chromaffin granule membranes exhibit several peaks in the 15-35 degrees C region. Extraction of cholesterol increases the size of the melting peaks. Addition of Ca2+ ions does not seem to influence the lipid transitions.
