The ability to remotely trigger CRISPR/Cas9 activity would enable new strategies to study cellular events with greater precision and complexity. We developed a method to photocage the activity of the guide RNA called ‘CRISPR-plus’ (CRISPR-precise light-mediated unveiling of sgRNAs). The photoactivatable capability of our CRISPR-plus method is compatible with simultaneous targeting of multiple DNA sequences and supports numerous modifications that can enable guide RNA labeling for use in imaging and mechanistic inquiries. Turn ‘ON’ CRISPR with light: CRISPR can be brought under the control of light simply by hybridizing a single chimeric guide RNAs (sgRNA) with its complementary oligonucleotide containing photocleavable groups (protector oligonucleotide). These protected sgRNA (p-sgRNA) remain inactive, blocking CRISPR activity, until the protector oligonucleotides are cleaved by a remote light trigger.
