The invention discloses a fast PCR reaction chip and a fast fluorescence quantitative detector. The PCR chip comprises a panel and a bottom membrane. At least one reaction pool is arranged on the bottom surface of the panel, and the reaction pool is not connected with the panel. Sample adding holes and exhaust holes are arranged on both sides of the reaction pool to connect with the top surface of the panel, and the bottom membrane is attached on the bottom surface of the panel, and the panel is made of transparent material. When the PCR chip is placed on the temperature control module, the bottom membrane is close to the temperature control module. After the sample is added, the PCR reaction liquid in the reaction pool above the bottom membrane is only separated from the temperature control module by a layer of bottom membrane. The cooling capacity or heating capacity of the temperature control module can quickly pass through the bottom membrane and be transmitted to the PCR reaction liquid. Compared with the plastic plate, the heat conduction speed of the film is faster and the heat conduction is more uniform, so that the PCR reaction liquid can be rapidly heated or cooled Fast PCR. The heating and cooling tablets of the rapid fluorescence quantitative detector are placed horizontally, the PCR chips are placed horizontally on the heating and cooling tablets, and the bottom film is close to the plane of the heating and cooling tablets. The cooling capacity or heating capacity of the heating and cooling tablets can be quickly and evenly transmitted to the PCR reaction liquid.

技术介绍
PCR扩增仪又称为PCR基因扩增仪、PCR核酸扩增仪、聚合酶链反应核酸扩增仪,是利用PCR(Polymerasechainreaction,聚合酶链反应)技术对特定DNA扩增的一种仪器设备,被广泛运用于医学、生物学实验室中,可以用于传染病的诊断、亲子鉴定等。基于PCR反应三步骤的原理,PCR扩增仪需要设置变性-退火-延伸3个温度点,在标准反应中,双链DNA在90~95℃变性,再迅速冷却至40~60℃,引物退火并结合到靶序列上,然后快速升温至70~75℃,在TaqDNA聚合酶的作用下,使引物链沿模板延伸,因此PCR扩增仪对于反应液温度快速切换以及精确的控制尤为重要。快速荧光定量检测仪是一种在普通PCR扩增仪的基础上增加荧光信号采集系统和计算机分析处理系统的PCR扩增仪,利用同位素、荧光素等标记PCR扩增时加入的引物,使用引物和荧光探针同时与模板特异性结合扩增的原理,通过荧光信号 ...
