| 摘要 |
The invention relates to the use of a polysaccharide having at least four saccharide units, such as stachyose,as a glass-forming agent for the freeze-drying of a reaction mixture comprising an enzyme. In particular, the enzyme is a polymerase useful in a nucleic acid amplification reaction such as a Polymerase Chain Reaction. Compositions comprising such polysaccharides as well as methods for preparing them, kits containing them and methods for using them form further aspects of the invention. |
