The present application relates to the technical field of
gene mutation detection, and particularly relates to a
system, method and application for detecting
exon skipping
mutation.The present application constructs a self-catalytic
system based on specific double recognition induction of
CRISPR-Cas12a, which is used for sensitive and reliable detection of MET 14
exon skipping
mutation of
lung cancer patients.The
system can effectively release the
fluorescence signal through the Cas12a auxiliary
cutting, and further realize
signal amplification through the self-catalytic mechanism.The present application can solve the technical problems of the existing
exon skipping
mutation detection system, such as complex detection process, long time consumption, and unsatisfactory detection accuracy.The detection system of the present application has high sensitivity, stability and good reproducibility, and the method has low cost, simple operation, short detection period, good specificity, and low
false positive rate and false negative rate.The present application is suitable for clinical sample determination and has an ideal application prospect.
