Abstract
The invention relates to a nucleic acid removing agent, which belongs to the field of molecular biology. The nucleic acid removing agent contains the following components in percentage by volume: 5%-10% of an oxidant, 0.1%-3% of a chlorine-containing reagent, 0.1%-3% of an acid-containing reagent, 0.1%-2% of a stabilizer, 1%-8% of a surfactant and the balance deionized water. The nucleic acid removing agent is odorless, is mild in properties, possesses no irritation effect, is simple and convenient to operate, is convenient to store and long in storage period, can be directly sprayed on the ground, wall surfaces and tabletops of laboratories, the tabletops of biosafety cabinets, the surfaces of pipettors, the outer surfacess of various instruments, the outer walls of centrifugal tubes andthe like during use, and can also be directly used for wiping the instruments, the tabletop, the tabletop and the like. By using the nucleic acid removing agent, nucleic acid fragments can be effectively degraded within several minutes, and laboratory aerosol pollution is prevented.
Description
technical field [0001] The invention belongs to the field of molecular biology, and in particular relates to a nucleic acid removing agent. Background technique [0002] Since its inception in 1985, PCR technology has been widely used in all life-related sciences such as medicine, forensic science, agronomy, and biology, and has become one of the necessary basic technologies in the field of life research. In particular, the fluorescent PCR technology developed based on ordinary PCR technology is more than 100 times more sensitive than ordinary PCR, and is favored by a large number of scientific researchers. It has become a common method for the diagnosis of disease pathogens in the fields of medicine and veterinary medicine. But at the same time, the unique principle of PCR technology tells us that one molecule will produce billions of molecules after PCR reaction. This high sensitivity means that during the operation of PCR, the environment and laboratory are extremely slig...
