DNA probe library for hybridization with microsatellite instability related microsatellite loci, detection method and kit

摘要

A DNA probe library for hybridization with microsatellite loci associated with microsatellite instability (MSI) detection. The said DNA probe library comprises one or more DNA probes that are capable of hybridizing with the MSI status-related microsatellite loci. Among the said DNA probes, probes for the MSI-related microsatellite loci are shown in the following sequences: SEQ ID NOS. 1-66. In addition, the present invention provides a method for enriching and detecting the MSI-related microsatellite loci using the probe library. The combination of this method and next-generation sequencing technology (NGS) can greatly improve the sensitivity, accuracy and comprehensiveness of the MSI detection.
