External Controls

External controls are necessary in assuring that test systems are performing according to the manufacturer’s specifications. ATCC has the strains and nucleic acids you need to verify and evaluate assay performance.

During assay development, or when using a pre-qualified assay or sequencing tool, it is important to select appropriate external controls to evaluate and verify the performance of each process. This testing is imperative in tracking drift and run-to-run variation within a procedure. To aid in assay validation, ATCC offers an expansive array of authenticated cultures and nucleic acid preparations for use as external controls in:

  • Nucleic acid extraction
  • Process verification
  • Amplification
  • Proficiency testing

ATCC® Genuine Cultures and ATCC Genuine Nucleics® are prepared as high-quality, authenticated materials backed by meticulous quality control procedures, making them ideal as external controls for process validation.
