Web1 Dec 2024 · CRISPR-Cas12a, an RNA-guided DNA targeting endonuclease, has been widely used for genome editing and nucleic acid detection. As part of the essential processes for both of these applications, the two strands of double-stranded DNA are sequentially cleaved by a single catalytic site of Cas12a, but the mechanistic details that govern the generation … Web14 Jun 2024 · Incubate them at 37oC for 16 hours. Pick numerous recombinant phagemid transformed colonies and one or two-parent vector transformed colonies. Shift them to sterile 15ml culture tubes having 2-3ml of 2x YT medium (having 60ꭒg/ml ampicillin). The single-stranded DNA yield is affected by multiple factors.
