Problems solved by technology

However, because the current PCR process still has a long reaction time and needs batch reactions, that is, the problem of a long cycle, the next batch of reactions must wait for the completion of the previous batch of reactions, which causes the PCR instrument to be inefficiently used. It also affects work efficiency

Abstract

The invention discloses a method for extremely fast nucleic acid amplification detection. The nucleic acid amplification reaction tube is repeatedly placed in an ultra-high temperature zone and an ultra-low temperature zone for a short time. A temperature point between 10°C-40°C; such 30-45 cycles, complete the nucleic acid amplification detection process within 8-15 minutes. The invention also discloses a reactor for extremely fast nucleic acid amplification, which includes an ultra-high temperature reaction zone with a fixed temperature in the adjustment range of 100°C-150°C and a fixed temperature in the adjustment range of 10°C-40°C Ultra-low temperature reaction zone. The invention also discloses an operating software system and equipment for the above-mentioned extremely fast nucleic acid amplification.

Description

technical field [0001] The present invention relates to a gene detection method used in the fields of biology, medicine, etc., and its equipment and application, in particular to a method for extremely fast nucleic acid amplification, and its equipment and application. Background technique [0002] Polymerase Chain Reaction (Polymerase Chain Reaction), referred to as PCR, has become a routine technique for nucleic acid detection. A typical PCR program usually consists of three basic reaction steps of repeated high temperature denaturation-low temperature renaturation-suitable temperature extension, that is, high temperature treatment at 90-95°C for about 10-30 seconds, and then cooling down to 50-65°C, maintain for about 10-30 seconds, then raise the temperature to about 72°C, maintain for 30-60 seconds, and so on for 30-40 cycles. According to the typical PCR three-step cycle amplification process program recorded in the book "Molecular Cloning Experiment Guide", it is usu...
