水貂 IFN-α、IFN-β及 IFN-γmRNA 荧光定量RT-PCR 检测方法的建立及应用
Establishment and Application of Real-time RT-PCR for Detection of Mink Interferon-α,Interferon-βand Interferon-γmRNA
摘要
Abstract
In this study,the methods of SYBR GreenⅠreal-time quantitative RT-PCR assay for detection of mink IFN-α,IFN-βand IFN-γ(MiIFN-α,MiIFN-βand MiIFN-γ)mRNA were established using four pairs of specific primers designed according to the MiIFN-α,MiIFN-βand MiIFN-γgene sequences,with the mink glyceraldehyde-3-phosphate dehydrogenase (MiGAPDH)mRNA as an internal control.The target genes were amplified by RT-PCR and inserted to pMD18-T vector as the standard recombinant plasmids for the establishing the real-time PCR standard curves.The results showed that the Ct values of MiIFN-α,MiIFN-β,MiIFN-γand MiGAPDH mRNA had good linear relationships (R2 =1.00)with the standards from 10 copies/μL to 107 copies/μL,and the melting curve showed a single peak.And the sensitivity assay results showed that the genetic test minimum value ware 10 copies/μL.The coefficient variations of inter-assay and intra-assay were both less than 4.5%.The result of clini-cal test showed that the relative expressions of MiIFN-α,MiIFN-βand MiIFN-γreached the highest level.The ex-pressions of MiIFN-αwas 100 times higher than that of MiIFN-βand MiIFN-γ and increased significantly during the infection period.The detection methods provide an effective tool for quantitative analysis of mink IFN-α,IFN-βand IFN-γmRNA.关键词
