Abstract

This invention relates to the field of detection and provides a bioaerosol sampling solution. The bioaerosol sampling solution comprises the following components in the following proportions: a chelating agent, a buffer, a surfactant, a protein denaturant, a humectant, and a solubilizer. The sampling solution with specific components of this invention can directly achieve a lysis effect, thereby integrating the nucleic acid extraction step into the collection step, reducing existing sampling operations, reducing system losses, and achieving highly efficient collection results. Simultaneously, the sampling solution with specific components of this invention has excellent bactericidal effects on Gram-negative and Gram-positive bacterial solutions of different concentrations, effectively preventing microbial toxicity and personnel infection during the sampling process. Furthermore, when using the sampling solution of this invention for sampling, there is no need for repeated removal / replacement, further ensuring the potential biosafety of operators.
