Archer SureShot™ Fusion Controls

FFPE Controls for ALK, RET, ROS1 Fusions

Archer® SureShot™ ALK RET ROS1 controls are formalin-fixed, paraffin-embedded (FFPE) curls of homogeneously mixed, genetically defined ALK, RET and ROS1 fusion-positive cell lines developed in collaboration with Horizon Discovery, Ltd.. Curls contain EML4-ALK, CCDC6-RET, and SLC34A2-ROS1 fusions. When used alongside the Archer FusionPlex Panels containing ALK, RET, or ROS1 fusions, the SureShot controls are a powerful measure of extraction, library preparation, sequencing, and panel performance.


  • One FFPE sample, 3 fusion events
  • Suitable for use alongside multiple FusionPlex panels
  • Perfect for evaluations and lab optimizations
  • Negative controls are also available

Positive Controls

Genetically defined fusion events

The Archer SureShot ALK, RET, ROS1 Positive Controls consist of 4 FFPE curls containing cell lines with physiologically relevant abundance of ALK, RET and ROS1 fusions, specifically:

  • EML4-ALK variant 1
  • ROS1-SL34A2
GSP Primer Tubes

Each curl contains a defined mixture of 3 different ALK, RET, and ROS1 fusion-positive cell lines along with a wild-type parental strain.

Broad FusionPlex Panel Compatibility

Libraries were created from material extracted from SureShot Positive Controls and the FusionPlex assays indicated in the graph below. The data reports the number of unique ALK, RET or ROS1 start sites detected using each FusionPlex assay across 7 replicates. The data supports the table information below, wherein any FusionPlex panel that includes ALK, RET and/or ROS1 primers detected the respective fusion in the SureShot Positive Control extractions. The dotted red line indicates the threshold criteria at which Archer Analysis software calls a "strong evidence", or valid fusion (3 unique start sites).

SureShot Controls

The table below indicates which FusionPlex panels include ALK, RET and/or ROS1 fusions, demonstrating the broad compatibility of the SureShot Positive Controls with FusionPlex panels.

Negative Controls

The Archer SureShot Negative Controls consist of 4 FFPE curls composed of 100% wild-type cells that carry no target gene fusion. These controls are suitable negative controls for all FusionPlex panels.
