Methods and reagents for molecular proximity detection using RNA-guided nucleic acid binding proteins
The present disclosure provides reagents and methods for molecular proximity detection of specific endogenous nucleic acids in situ using RNA-guided nucleic acid binding proteins.
1. A complex comprising at least one probe comprising (i) an engineered, non-naturally occurring Clustered Regularly Interspersed Short Palindromic Repeats (CRISPR)-associated (Cas) (CRISPR/Cas) system comprising a Cas9 protein and a guide RNA and (ii) an oligonucleotide that is linked directly or indirectly to the CRISPR/Cas system, wherein the guide RNA comprises the nucleotide sequence of SEQ ID NO:9.
2. The complex of claim 1 , wherein the Cas9 protein comprises two functional nuclease domains, one functional nuclease domain, or no functional nuclease domains.
3. The complex of claim 1 , wherein the complex comprises a first probe comprising (i) the CRISPR/Cas system and (ii) a first oligonucleotide that is linked to the guide RNA by covalent or non-covalent bonds.
