To investigate the relationship between the single nucleotide polymorphism (SNPs) of the bcr and abl gene and chronic myelogeous leukemia (CML), the 9 sequence-tagged sites (STS) in bcr and abl gene were screened by DNA pooling and denaturing high performance liquid chromatography (dHPLC), and the results were varified by sequencing.
为了探讨bcr和abl基因的单核苷酸多态性(SNP)与慢性髓细胞性白血病(CML)的关系,利用DNA池(DNApooling)结合变性高效液相色谱(dHPLC)技术对bcr和abl基因上的9个序列标签位点(sequencetaggedsite,STS)进行序列变异的筛查分析,并通过测序对筛查结果进行验证。
A difference marker sequence CTTTTTTCTTTT was selected from C-strain and other strains of CSFV,and specific PCR primer pair and nested-PCR primer pair were designed at the basis of previously published sequences of CSFV.
根据已发表的猪瘟病毒(CSFV)核苷酸序列,筛选出C-株与其他毒株的核苷酸序列差异标记CTTTTTTCTTTT,并设计包含此标记序列的CSFV特异性PCR引物对及nested-PCR引物对。
