The Introduction of Intramolecular Covalent Cross-linkages into Ichthyocol Tropocollagen with Monofunctional Aldehydes

Abstract

Protein Concentration-Solution concentrations were determined by the micro-Kjeldahl nitrogen procedure of Miller and Houghton (15).The percentage error for duplicate samples assayed the same day was &l %.Duplicate samples assayed on different days had a maximal &3 $& error.Purified ichthyocol had a nitrogen content of 18.4%.
