Fig. 4From: Identification of EML4-ALK as an alternative fusion gene in epithelioid inflammatory myofibroblastic sarcoma a. PCR products of 3 primer pairs. The length of the products was 199Â bp (Primer pair 1), 222Â bp (Primer pair 2) and 209Â bp (Primer pair 3). b, c. Direct sequencing of the products of Primer pairs 2 and 3 confirmed an EML4-ALK fusion gene detected by RNAseq. The product of Primer pair 1 did not reveal the presence of a fusionBack to article page
