Verified and dedicated negative control for nucleic acid testing (NAT) assays detecting single or multiple human respiratory pathogens.

  • Designed to validate and monitor human sample processing, extraction, amplification, and detection as an external run control.

  • Human sputum-like matrix containing A549 epithelial cells (20,000 cells/mL) from human lung carcinoma.

  • Pre-screened negative specimen, tested free of nucleic acids from a range of respiratory pathogens.

  • Lyophilized monodose presentation: reconstitute before use.

  • Non-infectious material.

  • Compatible with multiple molecular platforms.
