Fig. 5From: 5′/ 3′ imbalance strategy to detect ALK fusion genes in circulating tumor RNA from patients with non-small cell lung cancerCorrelation analysis of the expression value of the ALK fusion genes by 3′/5′ portion qPCR and the percentage of the ALK fusion (+) cells by FISH. The expression value of the ALK gene in the patients with ALK fusion genes has a significant positive correlation with the percentage of the ALK fusion (+) cells identified by FISH in the patients. The lowest cross point indicated the expression value 32.9 on the X axis corresponding to that of 15% ALK fusion (+) cells on the Y axis by the FISH methodBack to article page
