Our new preprint is out - please share!
We asked: How can we make CRISPR knockouts in vivo more efficient? And set up an assay that enables detection of CRISPR cutting with 100s-1000s of sgRNAs over entire chromosome arms in living animals.
Grab a ☕ and let’s dive in. 🧵🧪 1/n

Day 23/31
Prompt FIREFLY
Pdb: 2D1R
Luciferase: firefly enzyme catalyzes a light-producing reaction that makes fireflies glow.
Next: ROWDY
Suggestions?

Delighted to share Array Assembler — a web tool for designing oligos for generating crRNA arrays for #Cas12 and #Cas13 systems. Input spacers and key plasmid details to generate an order-ready XLSX of oligos, streamlining array creation while minimising cost, time, and errors. Happy CRISPRing!

PIWI clade Argonautes are essential for transposon silencing. Without them, animals are sterile due to massive transposon activity.
But how does piRNA-guided target interaction translate into silencing?
