CASdetec: new CRISPR-based SARS-CoV-2 detection platform detects nucleic acids with high sensitivity and specificity

To add to existing CRISPR-based nucleic acid detection protocols, a team of researchers recently established a new SARS-CoV-2 detection protocol based on their previously reported platform - CDetection (Cas12b-mediated DNA detection). They combined nucleic-acid amplification methods and sample treatment protocols with CDetection and established an integrated nucleic acid detection platform called CRISPR-assisted detection or CASdetec. CASdetec has a detection limit of 1×104 copies/mL for SARS-CoV-2 pseudovirus, without any observed cross-reactivity.
