Abstract:
Recombinase polymerase amplification (RPA) is an emerging method for nucleic acid amplification. It can be performed under low-temperature conditions, making it suitable for point-of-care testing. Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR-associated protein 13 (CRISPR/Cas13a), a type Ⅵ CRISPR-Cas system, employs a single-subunit RNA-guided Cas endonuclease to target exogenous RNA and exhibits distinct trans-cleavage activity. The integration of CRISPR/Cas13a with RPA technology significantly enhances detection sensitivity and accuracy, demonstrating considerable potential for molecular diagnostics. The RPA-CRISPR/Cas13a platform has achieved notable success in areas such as food safety, environmental monitoring, and clinical diagnosis, and has become an important tool in modern biomedical research. This article provides an in-depth analysis of the fundamental principles of RPA-CRISPR/Cas13a technology and comprehensively reviews its applications in pathogenic microorganism detection, aiming to offer new insights for accurate pathogen diagnosis.
