    摘要: The present invention concerns methods and compositions to prepare biological samples to preserve the macromolecules in the samples. Embodiments of the invention concern the use of a soak solution that contains one or more water-miscible solvents. A sample is incubated with the soak solution to the point of saturation at a temperature above the melting temperature of the water-miscible solvent but below 0° C. The use of methods and compositions of the invention allow for subsequent preparation or analysis of the samples.

    摘要: There is disclosed herein an oxygen absorbent composition comprising an organic oxygen absorbent (A) which neither absorbs nor releases moisture and in which an oxidizable main component is supported on a porous silicate having an average pore diameter of 200 to 5,000 .ANG., and a formaldehyde absorbent (B) which neither absorbs nor releases moisture and is at least one of an amine, a thiol and a sulfonic acid that is supported on a porous carrier. According to this invention cultural assets made of organic materials which are required to be kept in a medial humidity atmosphere can be preserved in an atmosphere of a medial humidity, a low oxygen concentration and a low formaldehyde concentration by the use of the disclosed oxygen absorbent composition.
