Abstract: The present invention relates to the technical field of biology, and in particular relates to a lytic composition and an application thereof, a kit, a method for preparing nucleic acid by utilizing the lytic composition, and a nucleic acid analysis method. A lytic product obtained in the present invention can be directly used for the nucleic acid analysis method without purifying the nucleic acid. According to the lytic composition disclosed by the present invention, multiple biological tissues and cells are lysed so as to release the nucleic acid of the cells into a solution, the nucleic acid in a whole-cell lysing and mixing state directly serves as a template without using a conventional nucleic acid separation and purification process after termination of the reaction, and nucleic acid amplification analysis is guided. For example, nucleic acid amplification is performed by a real-time fluorescence qPCR, etc.
