Description

Method and device for adjusting parameters of hybridization reactor
Technical Field
The application relates to the technical field of nucleic acid molecule hybridization, in particular to a method and a device for adjusting parameters of a hybridization reaction instrument.
Background
Currently, hybridization is a common method of molecular biological detection, and both of the hybridization are the probe used and the nucleic acid to be detected. The nucleic acid molecule hybridization has high sensitivity and high specificity, so the technology has been widely used in the field of molecular biology in the aspects of screening cloned genes, preparing enzyme digestion maps, qualitatively and quantitatively detecting specific gene sequences in genome, diagnosing diseases and the like. Therefore, it has not only a wide range of applications in the field of molecular biology, but also an increasing range of applications in clinical diagnostics.
In the prior art, the hybridization effect of the artificial hybridization instrument is better than that of an automatic hybridization instrument, because an experimenter of the artificial hybridization instrument can slightly adjust reaction parameters according to the past experience and the state of a biochip according to time and random strain in operation, thereby realizing better hybridization effect. Aiming at program solidification of an automatic hybridization instrument, liquid is discharged according to the setting of solidification time, and micro-parameter adjustment cannot be intelligently carried out according to the state of a biochip, so that defects including poor background, shallow contrast points or no signal, even false positive and false negative can be caused; in addition, the existing automatic hybridization apparatus has a disadvantage in temperature control. The temperature control of the current hybridization apparatus is to deduce the temperature of the biochip by heating the reaction chamber and feeding back the temperature of the reaction chamber through a fixed temperature sensor. Since the reaction temperature of the biochip is indirectly obtained, there is a large error, thereby affecting the hybridization effect. In particular, biochip hybridization reaction temperatures may be gradually distorted as performance degradation occurs after a period of use of an automated instrument. The reaction time of each hybridization stage is strongly related to the time when the biochip reaches the reaction temperature. The full-automatic hybridization instrument has the condition that the reaction time length can not be accurately controlled according to the dynamic condition because of the excessively high or excessively low distortion condition of the reaction temperature of the biochip.
