Abstract: The present invention relates to a exsiccated or lyophilized composition comprising: a nucleic acid polymerization enzyme and cellobiose, in which the enzyme is stable for a period of time, even at a temperature of up to 55° C. The composition of the invention can also comprise further reagents, such as salts, primers specific for a template DNA present in a sample, probes, etc. The invention relates to a method for preparing an exsiccated or lyophilized composition comprising a nucleic acid polymerization enzyme and cellobiose, possibly in containers, in which the enzyme is lyophilized and ready for use in molecular biology applications upon addition of the sample.
