ABSTRACT:
A method of preserving delicate biological substances or organic compounds (a) in a dry state and/or (b) at elevated temperatures and/or (c) under irradiation comprises incorporating in a system containing the said substances or compounds, a sugar or a sugar derivative selected from (i) a non-reducing glycoside of a polyhydroxy compound selected from sugar alcohols and other straight chain polyalcohols, or (ii) a non-reducing oligosaccharide selected from raffinose, stachyose and melezitose. In particular, methods for preserving dehydrated agarose gels comprising adding lactitol or glucopyranosyl-mannitol or glucopyranosyl-sorbitol to the gel during formation and prior to dehydration are disclosed.
