Abstract: The present disclosure provides a novel hybrid capture probe for enrichment of a target nucleic acid sequence. Its principle is that a probe sequence is divided into three segments: a middle segment is a target sequence binding segment; a 5? end segment of one probe can be complementarily paired with a 3? end segment of another probe, and a 3? end segment of one probe can be complementarily paired with a 5? end segment of another probe. This novel probe can bind more robustly to a target sequence, and has better effects in hybrid capture and targeted enrichment at low starting amounts or small target regions (Panels) compared with traditional hybrid capture probes.
