Can antigen detection be carried out without preservation solution?

Yes The main components of novel coronavirus antigen detection water are physiological saline, trihydroxymethyl aminomethane hydrochloride and a small amount of preservatives, among which physiological saline accounts for 99.7%, which can be used to detect RNA in novel coronavirus. The trihydroxymethyl aminomethane hydrochloride is often used in the extraction and purification of protein and DNA or RNA substances. For example, if the water used for novel coronavirus antigen detection is accidentally lost, it can be replaced by cold boiled water at home, but it should not be stored for a long time, so as to avoid inactivation of DNA or RNA substances and inaccurate test results.
