AcroMetrix MultiMix FFPE Controls from Life Technologies, Carlsbad, Calif, are process controls for the isolation, purification, and detection of somatic genetic variants in research oncology testing. The control consists of cells in a synthetic tissue that has been formalin-fixed and paraffin-embedded and sectioned to 10 microns thick. Routine use of the controls enables laboratories to monitor day-to-day workflow precision and identify possible variations between lots of assay reagents and operators. They can also assist in identifying increases in random or systematic errors in testing systems. For more information, visit Life Technologies.
