title: Measurement of rat brown-adipose-tissue mitochondrial uncoupling protein by radioimmunoassay: increased concentration after cold acclimation.
abstract: A specific antiserum has been raised against the 32 000-mol.wt. uncoupling protein from the mitochondria of rat brown adipose tissue and a sensitive radioimmunoassay for the protein has been developed. The uncoupling protein is present in large amounts in brown adipose tissue; its concentration is increased substantially by cold acclimation. The protein has not been detected in the liver, heart, or parametrial white adipose tissue of rats.
