Zusammenfassung:Disclosed are a probe for nucleic acid enrichment and capture and a design method thereof. The probe consists of a sense strand probe and an antisense strand probe, wherein both the sense strand probe and the antisense strand probe are probes without an overlapping design, and both are 30-89 bases in length. The 3' or 5' of the probe is biotin-labeled and can bind to the avidin on the magnetic beads. The two-way probe can increase the specificity of the capture (i.e. reducing the capture of genomic DNA at non-target sites), can significantly increase the capture of the sample mutant DNA and can increase the original copy number of the captured sample nucleic acid.
