Fig. 2From: Next-generation sequencing facilitates detection of the classic E13-A20 EML4-ALK fusion in an ALK-FISH/IHC inconclusive biopsy of a stage IV lung cancer patient: a case reportGenetic analysis of the biopsy and surgical specimen. a Reads of the E13-A20 EML4-ALK fusion transcript in the biopsy specimen. b Reads of the E13-A20 EML4-ALK fusion transcript in the surgical specimen. c FISH analysis of the biopsy specimen. Asterisk marks fused signal, arrow points to splits signal. d FISH analysis of the surgical specimen. Arrows indicate split signals. Both FISH pictures were taken at 100× magnification using oilBack to article page
