Sample preservation solution capable of digesting mucoprotein

The invention relates to the technical field of biology, in particular to a sample preservation solution capable of digesting mucoprotein. The composition provided by the invention comprises guanidinium isothiocyanate, tris (2-carboxyethyl) phosphine hydrochloride and ethylene diamine tetraacetic acid dihydrate, and can be used for rapidly digesting mucoprotein substances carried on samples such as throat swabs and nose swabs, and the carried mucoprotein substances can be digested within 20 seconds after the swabs are put into a preserving fluid; convenience is provided for subsequent sample transfer and nucleic acid extraction. 本发明涉及生物技术领域，特别涉及可消化粘蛋白的样本保存液。本发明提供的组合物包括异硫氰酸胍、三(2-羧乙基)膦盐酸盐和乙二胺四乙酸二钠二水合物，能够快速消化处理咽拭子、鼻拭子等样本上携带的粘蛋白物质，在将拭子放入保存液后在20s内即可将携带的粘蛋白物质消化掉，为后续样本的转移、核酸提取提供便利。
