2results about How to "Efficient liquefaction" patented technology

The present application provides a liquefaction combination product for viscous biological samples, a nucleic acid amplification system, a nucleic acid detection system, a processing method and applications. The liquefaction combination product comprises a component a and further comprises or does not comprise a component b; the component a is an aqueous solution I or a mother liquor of the aqueous solution I comprising the following components: acetylcysteine 3% to 15% (w / v), sodium chloride 20 mM to 500 mM, potassium chloride 50 mM to 120 mM and 50 to 1000 mM strong base, calculated as monobasic base; the component b is citric acid or an aqueous solution thereof. Through the synergistic effect of the above components, the liquefaction combination product can directly and quickly fully liquefy the viscous biological sample at room temperature, can avoid the sample pollution problem caused by aerosol generated by heating, and does not need to perform complex steps such as heating. The sample processed by the liquefaction combination product can stably store nucleic acid, and can realize extraction-free amplification and extraction-free detection.
