TrueMark™ Comprehensive Microbiota Control

The TrueMark Comprehensive Microbiota Control contains a linearized multi-target plasmid pool with microbial target sequences commonly used on Custom OpenArray panels. The control has targets relevant to many microbial profiling applications, including respiratory tract, urinary tract, vaginal microbiota, and antibiotic resistance research. The control can be included as a positive control for panel-specific amplification. It is available in two concentrations: 1 x 10⁵ and 5 x 10⁷ copies/μL. The higher concentration can be used to determine parameters necessary for analytical validation (e.g., limit of detection and Ct cut-off values).

The plasmid also contains target sequences for TaqMan Universal RNA Spike In/Reverse Transcription (Xeno) Control, TaqMan Universal Extraction Control Organism (B. atrophaeus), and the human RNase P RPPH1 gene. During real-time PCR, the control can be used as a stand-alone sample to verify assay performance and to help with troubleshooting.

Note: This product will be updated on an annual basis to ensure coverage of the most popular microbial targets, and performance will be measured to ensure consistency between versions.
