根据hsp70、hsp90和GAPDH基因mRNA序列,设计并合成3对引物,将PCR扩增的基因片段克隆到pGEM-T载体,重组质粒经筛选、鉴定,体外转录出RNA,系列稀释作为阳性标准品,用于标准曲线的绘制和样品检测,并用持家蛋白GAPDH基因对样品进行归一化,建立了一步法实时荧光定量RT-PCR技术平台,并对其扩增效率、敏感性、特异性进行了检测。结果证明,建立的一步法荧光定量RT—PCR技术可以真实地反映反应管中模板的数量,可用于猪矗驴。、hsp。和GAPDH基因mRNA水平的检测。
According to the specific sequence of hsp90, hspgo and GAPDH mRNA, the primers were designed and synthesized. The fragments generated by RT-PCR were cloned into the pGEM-T vector. The positive recombinant plasmids were used to transcript RNA in vitro and the RNA were used as standard quantitative template to make the standard curve and establish fluorescence quanti- tative RT-PCR ( FQ RT-PCR) method. The efficiency, sensitivity and specificity of the RT-PCR method were tested. The results showed that the FQ RT-PCR method was external and could be used to detect the hsp70, hsp90 and GAPDH mRNA transcription of pigs.
