Each Extraction Control (ExC) contains inactivated whole-organism mix designed to mimic real-world clinical samples and challenge nucleic acid extraction workflows.

The STI-ExC provides a realistic simulation of sexually transmitted infection sample matrices by incorporating a range of inactivated organisms that span key pathogen types. These include intracellular bacteria, fastidious extracellular bacteria, and protozoan pathogens often found in urogenital samples. This extraction control is ideal for validating the robustness of lysis protocols and nucleic acid recovery in complex sample types, especially for multiplex assays and direct amplification formats.
