| 摘要 |
The invention is directed to tools, compositions and methods for collecting, storing, transporting, isolating and detecting macromolecules such as nucleic acid sequences obtained from specimens. The compositions are one-step formulations for killing or inactivating pathogens, inactivating enzymes, and releasing nucleic acids from the specimens that are prepared for further processing and/or analysis. In particular, the invention provides a single, one-step, sample collection and transport formulation that facilitates the concentration, extraction, isolation and analysis of nucleic acids, genes and genomes. |
