Pathogen tNGS Detection Panel

Overview of tNGS Technology

Pathogen targeted Next-Generation Sequencing (tNGS) stands as a widely embraced technology for the identification of pathogenic microorganisms. This approach predominantly follows two primary technical pathways: The first involves enriching target sequences through multiplexed amplicons, culminating in the formation of sequencing libraries. The second entails introducing a probe hybridization step. This step aims to capture the target segments from libraries, thus augmenting the concentration of pathogenic sequences.

The former methodology permits the realization of multiple amplifications using thousands of amplicons. Despite its relatively simple and expedited experimental procedures, this technique exhibits a certain degree of instability and an associated risk of amplification failures. In contrast, the latter approach boasts greater scalability. Commercially available solutions of this kind leverage millions of probes to achieve a detection breadth akin to that of metagenome sequencing (mNGS). Consequently, this method addresses a key challenge posed by mNGS, namely the removal of host sequences through forward screening.

CD Genomics also provides Pathogens Capture Sequencing (tNGS) service.

Our tNGS Pathogen Panel

CDCAP Pathogen Panel stands as a cutting-edge tNGS solution utilizing hybridization capture. This innovative panel zeroes in on a meticulously curated array of signature sequences, thoughtfully chosen from a vast pool of pathogen genomes, encompassing viruses, bacteria, fungi, and parasites. Encompassing an extensive spectrum including 16S/ITS, housekeeping genes, drug-resistance-associated genes, and beyond, the panel's design is a testament to its comprehensiveness.

Through leveraging the robustness of probes, the panel achieves an elegant equilibrium between size and fault tolerance. With approximately 8,000 carefully selected probes, the panel is thoughtfully streamlined, yet without compromise on its information-enrichment capacity. This strategic design choice effectively democratizes its applications by significantly reducing the entry barrier.
