Currently, most of preservation solutions in nucleic acid sampling and preserving tubes in domestic markets contain guanidine substances (guanidine isothiocyanate, guanidine thiocyanate, guanidine rhodamine or the like). since the reaction between guanidine thiocyanate or similar chemicals and bleaching agent (sodium hypochlorite) generates a byproduct, namely cyanide gas, and the cyanide gas can bring health hazards to laboratory workers, the U.S. Food and Drug Administration (FDA) warns the laboratory workers not to use or receive such samples.
