EML4-ALK has been emerged as one of the most important driver oncogenes in lung cancer and the first targeted fusion onco-kinase to be identified in 4-6% of lung adenocarcinomas. Other Non-EML4 fusion partner genes including KIF5B, TGF, and KLC1 have also been reported. Over the last few years, ALK inhibitors have shown significant benefits in the management of ALK-positive non-small cell lung cancer (NSCLC) compared to conventional chemotherapy. 

QFusion™ ALK fusion gene detection kits provide an easy-to-use multiplex RT-qPCR assay that simultaneously detects the most prevalent EML4-ALK and KIF5B gene fusion breakpoints. This highly specific and sensitive assay requires a minimal amount of RNA, and it is a rapid and reliable alternative to the laborious FISH test.

QFusion™ EML4-ALK and KIF5B-ALK Fusion Gene Detection Test is CE/IVD-certified.

ALK Fusion Gene Variants Detected

Amplification Curve Generated by QFusion™ for FFPE Reference Materials

EML4-ALK fusion gene variant 1 could be successfully detected from the ALK fusion-positive FFPE reference material (RM) (blue line) but not the negative RM (green line). The internal control (IC) assay similarly amplified the positive and negative FFPE RMs (black and red lines), indicating that the total RNA input (50 ng) extracted from these RMs was about the same.
