|December 1, 1976
Abstract:
Preparation of (14C) Pro labeled protocollagen and requirements for its hydroxylation by PPH was investigated. Protocollagen can be prepared by centrifugation of the biological material at 15.000 X g. Substances in current use, viz catalase, bovine serum albumin and dithiothreitol were found unnecessary under the hydroxylation conditions used. A decrease in PPH in the testis and skin of rats with increasing age was demonstrated.
