title: Note on the effect of ageing on the neutral salt and acid soluble collagen from the intramuscular connective tissue of various species.
abstract: The neutral salt soluble (NSSC) and acid soluble collagens (ASC) from the intramuscular connective tissue of various species were extracted, purified and studied by optical rotatory dispersion, viscosity and polyacrylamide gel electrophoresis. No significant changes in the quantity of such soluble fractions, in the optical rotatory dispersion or in viscosity of the purified samples were observed during two weeks storage at 1 °C. Electrophoretical analysis suggested a decrease in the relative concentration of the α chains of the ASC. It was concluded that if there are changes in the NSSC or ASC of muscle during ageing these are not detected by the techniques employed.
