On the Level of Nucleic Acids in Bone Gelatins

Paper presented at a symposium on “Photographic Gelatin” organized by the Science Committee of the Royal Photographic Society on 19-22 September 1967 in Cambridge

Abstract

It is shown that nucleic acids are present in bone and that these are largely removed in the acid de-mineralization step. Initial extraction of nucleic acid by mineral add is quite rapid and is probably followed by conversion to apurinic acid. When the bone is extracted without acid treatment, as in the preparation of bone glue, the product is very rich in nucleic acids of relatively low molecular weight. The acid treatment also extracts small amounts of a protein material which may be a restrainer
