Evidence submitted for testing included a live round of ammunition, a spent shell casing, and swabs from a large-capacity magazine. A team of Signature Science analysts determined that the magazine and spent shell casing produced profiles suitable for … MORE

Universal RNA sequencing: Workflow validation

Validation of an unbiased metagenomic detection assay for RNA viruses in viral transport media and plasma: Preprint Available

Abstract: Unbiased long read sequencing holds enormous potential for the detection of pathogen sequences in clinical samples. However, the untargeted nature of these methods precludes conventional PCR approaches, and the metagenomic content of each sample increases the challenge of bioinformatic analysis. … MORE
