Application of differential scanning microcalorimetry to the study of cellular processes: heat production and glucose oxidation of murine macrophages.

Abstract
Differential scanning microcalorimetry provides a noninvasive method for studying heat evolution in living cells. This technique was used to measure the heat evolved by thioglycollate broth-elicited mouse macrophages, and the effects of NaF, KCN, cycloheximide and cytochalasins B and D on this parameter. The total heat evolved in the interval 10-37.degree. C scanned at 1.degree. C min-1 ranged from 300-2500 .times. 10-12 cal/cell, depending on cell density, glucose concentration and the presence or absence of various drugs.
