摘要: 本研究旨在建立定量检测小鼠β-actin mRNA表达水平的实时荧光定量PCR方法,为小鼠相关基因表达水平的分析提供方法。根据GenBank中登录的小鼠β-actin mRNA序列,针对保守区域设计并合成1对引物,建立了基于SYBR Green Ⅰ技术的小鼠β-actin mRNA荧光定量PCR方法。结果表明,该方法扩增效率高(97.7%),定量线性范围广(9.3×102~9.3×107拷贝/反应),可重复性强,无非特异性扩增和引物二聚体,最小检出量为9.3拷贝/反应。试验结果为β-actin作为内参基因用于小鼠相关基因转录水平分析提供了基础。

Abstract: The aim of present study is to establish a real-time PCR for quantitative analysis of mouse β-actin mRNA expression. A set of primer was designed according to the mouse β-actin mRNA sequence in GenBank. And a SYBR Green Ⅰ-based reverse real-time PCR (RRT-PCR) was successfully developed. The results showed that RRT-PCR assay established had a high amplification efficiency(97.7%),wide linear range(9.3×102 to 9.3×107 copies/reaction),good reproducibility and specificity. The detection limit was 9.3 copies/reaction. The results provided a basis for use of β-actin as a reference gene in gene expression analysis in mouse.
