Hi fellow C. elegans scientists, I've made a few videos that may be of use for new trainees working in worm labs. Hoping to add more in the future, but figured I'd share this resource as is in case it's helpful :)

🚀 Our new paper is out @natmethods.nature.com!

Kuffer & Marzilli engineered conditionally stable MS2 & PP7 coat proteins (dMCP & dPCP) that degrade unless bound to RNA, enabling ultra–low-background, single-mRNA imaging in live cells.

callista yee @csybio.bsky.social · 19d

done, I will set aside one for you 🥰

callista yee @csybio.bsky.social · 19d

I was pretty sure I never used this one then I looked it up and it was
unc-122p::gfp and now I feel dumb

also got a billion of cryo boxes but I haven’t figured out the best course yet with them… but they’re definitely $$$$$

New paper on the role of H3K4me3 at enhancers! We (led by Haoming Yu) used dCas9 epigenome editing to add H3K4me3 to intergenic enhancers. This was (1) sufficient to turn up transcription at open, active regions and (2) has no effect on target gene transcription. genesdev.cshlp.org/content/earl...
