Eric Joyce @ericjoyce.bsky.social · 16/09/2025We’re excited to share that, after receiving many requests each year from the research community for Oligopaint DNA & RNA FISH probes, we’re piloting a service to design & prepare probes for labs. Please share with colleagues who may benefit! ericjoycelab.com/oligopaint-f...ericjoycelab.comOligopaint Probe RequestsIn an effort to make Oligopaint FISH probes more broadly available to the research community, we offer DNA and RNA FISH probe design, synthesis, and generation. By dedicating a full-time staff memb… 0119
