Development of a one-pot RPA-cas12a/13a assay for simultaneous detection of HPV16 and HPV18.

ABSTRACT: The incidence of human papillomavirus (HPV)-related cervical cancers has been on the rise, and the affected population is increasingly younger. Early-stage prevention and screening initiatives have emphasized the critical necessity for reliable and rapid HPV detection technique. In this study, we devised a fluorescence-based assay that integrated one-pot Cas12a/13a with recombinase polymerase amplification (RPA) for the detection of HPV16 and HPV18. We exploited the cleavage activities of the Cas12a and Cas13a enzymes to specifically target the L1 gene of HPV16 and 18, respectively. The diagnostic efficacy of the CRISPR-Cas12a/13a system was assessed in identifying HPV by analyzing clinical samples and comparing it with the PCR method. The one-pot RPA-Cas12a/13a-based fluorescence assays e
