The present invention describes compositions and methods for releasing nucleic acids from cells in a form that is suitable for labeling/capture, amplification, or detection in a single reagent addition step. The compositions include a lipid, membrane fluidizing compound, enzyme for degrading cell structure, metal chelators, or one or more nucleic acid probes or primers complementary to the nucleic acid to be detected. The compositions are non-denaturing and non-inhibitory of enzymes or proteins that are used in nucleic acid release, amplification, labeling or detection. The invention also provides kits for performing the above methods.
本发明描述了一种将核酸从细胞中释放出来并以适合于标记/捕获、扩增或检测的形式的组合物和方法,该方法只需要一次试剂添加步骤。该组合物包括脂质、膜流动化合物、降解细胞结构的酶、金属螯合剂或与待检测的核酸互补的一个或多个核酸探针或引物。该组合物是非变性的,不会抑制用于核酸释放、扩增、标记或检测的酶或蛋白质。本发明还提供了用于执行上述方法的试剂盒。
