Preparationofnucleicacidprobes
Preparation of nucleic acid probesIn standard nucleic acid hybridization assays the probe is labeled in some way. Nucleic acid probes may be made as single-stranded or double-stranded molecules (see Figure 5.1), but the working probe must be in the form of single strands.Conventional DNA probes are isolated by cell-based DNA cloning or by PCR. In the former case, the starting DNA may range in size from 0.1 kb to......阅读全文
