PG - 399-402 AB - OBJECTIVE: To establish a repeat-free ROS1 gene fluorescence in situ hybridization (FISH) probe, and to compare its efficacy with those of commercial FISH probes in non-small cell lung cancer. METHODS: The probe was constructed by combining human Cot-1 DNA genome into double-stranded sequence, and then digested by duples specific nuclease to establish a repeat-free sequence. The final repeat-free ROS1 FISH probe was labeled by red and green fluoresceins. RESULTS: Compared with the commercialized probe, repeat-free FISH probe exhibited excellent efficiency and low signal to noise ratio (SNR) in samples. There was statistical significance in the difference between the hybridization rate of these two probes (P < 0.05) , but there was no difference between the accuracy rate (P > 0.05). CONCLUSION: The repeat-free ROS1 FISH probe significantly improves the probe hybridization efficiency and SNR in non-small cell lung cancer (NSCLC), resulting in an increased accuracy of detection.
