摘要
为构建检测内参基因β-actin mRNA表达水平差异的标准品,以成人外周血细胞的总RNA为模板、Random 6 mers为引物反转录合成cDNA,用该cDNA为模板PCR扩增人β-actin基因相应的cDNA片段,构建PMD-18-β-actin重组质粒,鉴定测序后,用荧光定量PCR制作标准曲线。结果外周血提取的总RNA完整性良好,构建的β-actin质粒经PCR扩增后得到一186bp的清晰条带,测序结果与目的片段完全一致,且质粒的原始浓度为2.39×1013 copies/mL,倍比稀释至2.0×104copies/mL均能得到良好的标准曲线(R2=1),提示构建β-actin基因荧光定量PCR标准质粒成功。
