dot-blot

基本解释

Two probing strategies have generally been employed, namely, dot-blot hybridization and fluorescent in situ hybridization.
两种研究方法被普遍采用，即斑点杂交法和荧光原位杂交。
Plasmid DNA and chromosomal DNA of the strain CEOI all obtained positive dot-blot to plasmid probe and chromosomal probe correspondingly.
质粒DNA和染色体DNA分别与质粒探针和染色体探针杂交出现典型的阳性杂交斑。
Comparison of the two methods of dot-blot hybridization and PCR showed that the latter was more sensitive than the former, which indicated the replication of DHBV was low in the tissues.
进一步比较了斑点杂交法和PCR法检测的结果，显示斑点杂交法检测组织中病毒远不如PCR法敏感，并提示可能组织中病毒复制量很低，以致用斑点杂交法检测出现很多假阴性。
