First Claim
Patent Images
1. A method of processing a target RNA, comprising:
- contacting the products of an RNA ligase-mediated ligation reaction with a CAS6 protein, wherein;
(i) said RNA ligase-mediated ligation reaction comprises;
a target RNA, an RNA ligase, and first and second adaptors that can ligate together to produce an adaptor dimer that contains a CRISPR stem loop; and
(ii) said CAS6 protein recognizes said CRISPR stem loop;
thereby preventing said adaptor dimer from being reverse transcribed.
