Molecular-based assays are powerful tools for the detection and identification of clinically relevant microbial pathogens. These technologies provide several advantages over traditional culture-based approaches, including rapid turnaround time, the potential for multiplexing, increased analytical sensitivity and specificity, and the ability to detect difficult-to-grow organisms. While molecular-based assays exhibit numerous benefits, they must be properly validated to guarantee accurate results and uncompromised data.
To meet this need, ATCC has made it a priority to provide a variety of ready-to-use, fully authenticated standards that can be used throughout the assay development process.
- Genomic nucleic acids – Quantitative whole-genome preparations aseptically prepared from minimally passaged ATCC cultures. Each preparation is supported by stringent quality control testing to ensure product authenticity and functionality.
- Synthetic nucleic acids – Quantitative DNA and RNA synthetically manufactured under an ISO 13485–certified process to include key target regions from select bacterial, protozoan, and viral species. These standards enable researchers to work with higher concentrations of target nucleic acid sequences for unculturable or high-containment species.
- Certified reference materials – Genomic DNA produced under an ISO 17034–accredited process to confirm identity, well-defined characteristics, and an established chain of custody. These materials are ideal for establishing sensitivity, linearity, and specificity during assay validation or implementation; challenging assay performance; and for benchmarking critical assay performance for regulatory submissions.
- Heat-inactivated preparations – Inviable, non-replicative preparations that are quantitated by Droplet Digital PCR or qPCR. These materials are ideal for use in molecular assays or as a process control (e.g., nucleic acid extraction through the qPCR amplification process).
So, skip in vitro culturing and let ATCC do the work for you! Explore our resources below to get started. If you can’t find exactly what you need, we can customize it for you. We can extract, purify, and quantify nucleic acids in several formats for use in your assays—contact us to get started.
SARS-CoV-2 Molecular Diagnostics Development
The highly pathogenic nature and transmission dynamics of SARS-CoV-2 have necessitated the availability of rapid, robust detection methods to ensure that infected individuals are treated in a timely manner. For commercial manufacturers developing SARS-CoV-2 molecular diagnostic tests for emergency use, the US Food & Drug Administration (FDA) has provided recommendations for validation studies to be conducted. To support this critical research, ATCC provides a variety of authenticated and clinically relevant materials for evaluating limit of detection, inclusivity, and cross-reactivity.Develop your SARS-CoV-2 assay
