Real-time fluorescent quantitative PCR instrument

Abstract

A real-time fluorescent quantitative PCR instrument comprises a case, wherein a control system connected with an upper computer is mounted in the case; a heat cycle system, a sampling part, a scanning part and a fluorescent detecting part, operated by control of the control system, are connected to the control system; the sampling part comprises a sampling motor mounted in the case and synchronous belts arranged on the two sides of the case; the synchronous belts on the two sides are connected through a rotating shaft and driven to rotate synchronously; the synchronous belts are wound on synchronous belt wheels driving the synchronous belts to move; the synchronous belt wheel on the side of the sampling motor is mounted on an output shaft of the sampling motor; push rod brackets are fixed on the synchronous belts; push rods driven by the push rod brackets to move are connected to the push rod brackets; connecting pins are mounted on the push rods; connecting brackets capable of moving up and down along the connecting pins are mounted outside the connecting pins in a sleeving manner; return springs are mounted outside the connecting pins and between the connecting brackets and the push rods in a sleeving manner; a test tube rack for placing samples is mounted between the connecting brackets on the two sides.

Description

Technical field [0001] The invention belongs to the fields of biology and medicine, and particularly relates to a real-time fluorescent quantitative PCR instrument. Background technique [0002] Real-time fluorescent quantitative PCR technology can realize the quantitative analysis of DNA template, which is of great significance to molecular biology research and medical research. The existing fluorescent quantitative PCR instrument has the following defects: the sample is put into the detection module or taken out of the detection module manually, and the temperature of the detection module will be very high after analysis, which will burn the operator, and the safety is not high. If you have to wait If you operate after cooling down, the waiting time is too long. Summary of the invention [0003] The invention provides a real-time fluorescent quantitative PCR instrument with higher safety performance, high automation and high reliability. [0004] The technical scheme adopted by ...
