DNA O-MAP uncovers the molecular neighborhoods associated with specific genomic loci DNA O-MAP enables proximity labeling at specific genomic loci in fixed cells using programmable oligonucleotides, revealing locus-proximal proteomes and chromatin interactions without genetic modifica...

The next iteration of O-MAP targeting genomic loci is now at eLife!!

DNA O-MAP enables proximity labeling at specific DNA loci took a ton of work from many lab members and collaborators, so it's really exciting to wrap up this paper with @oligopain.bsky.social!
