Figure Legend Snippet: BrCas12b characterization and one-pot specificity sensitivity testing. ( a ) Schematic of binary complex illustrating cleavage pattern of dsDNA target. ( b ) Temperature-dependent in-vitro cleavage assay of AacCas12b, AapCas12b, and BrCas12b targeting more restrictive PAM TTTG. 125 nM sgRNA:100 nM Cas12b:7 nM dsDNA was combined in 1X NEBuffer 2.1. The experiment was repeated (n = 2) with similar results. ( c ) Michaelis-Menten Kinetics of BrCas12b trans-cleavage at 62°C. ( d ) Differential scanning fluorimetry of AacCas12b, AapCas12b, and BrCas12b complexes. (e) Multiplexing using FITC to detect LAMP amplification and HEX to monitor trans-cleavage of BrCas12b. ( f ) – ( i ) Detection capability of BrCas12b via trans-cleavage against AacCas12b and AapCas12b at various temperatures. Fluorescence kinetics within 30 minutes was monitored using a HEX-based reporter. Shaded regions represent standard deviation (n = 3 replicates). STOPCovid LAMP primers were used in (f) to compare performance with AapCas12b. A different set of LAMP primers (DETECTR) with optimal performance at a temperature higher than 60°C were used in (g), (h), and (i). (+) denotes the presence of the SARS-CoV-2 genomic RNA control, and (-) signifies the non-template control (NTC). ( j ) – ( m ) Specificity testing using a pair of sgRNA and LAMP primers targeting SARS-CoV-2 variants (n = 3 replicates). ( n ) – ( q ) Limit of detection on N gene and S gene targeting alpha (B.1.1.7), beta (B.1.352), and delta (B.1.617.2), respectively (n = 3 replicates).
Techniques Used: In Vitro, Cleavage Assay, Multiplexing, Amplification, Fluorescence, Standard Deviation
