    • A method for disrupting frozen cells and/or tissue in a solid, frozen state in the presence of a solid denaturing substance is provided. The method comprises providing frozen cells and/or tissue in frozen solid form, adding thereto the solid denaturing substance in sold form, and applying mechanical force thereto for disruption of the frozen cells and/or tissue. The frozen cells and/or tissue include muscle cells and/or muscle tissue, wheat cells and/or wheat tissue, and maize cells and/or maize tissue. Further, the solid, denaturing substance in solid form is a crystalline substance and can be selected from urea, thiourea, guanidium chloride, guanidium thiocyanate and ammonium sulfate. Also the solid, denaturing substance in solid form is added to the frozen cells and/or tissue in frozen form in an approximately 1 to 20 fold (w/w) excess.
    • 提供了在固体变性物质存在下破坏固体,冷冻状态的冷冻细胞和/或组织的方法。 该方法包括以冷冻固体形式提供冷冻细胞和/或组织,向其中以出售形式加入固体变性物质,并施加机械力以破坏冷冻的细胞和/或组织。 冷冻细胞和/或组织包括肌肉细胞和/或肌肉组织,小麦细胞和/或小麦组织,以及玉米细胞和/或玉米组织。 此外,固体形式的固体变性物质是结晶物质,可以选自脲,硫脲,氯化胍,硫氰酸胍和硫酸铵。 此外,将固体形式的固体变性物质以约1至20倍(w / w)的过量加入到冷冻细胞和/或冷冻形式的组织中。
