🗝️ #DynaTag can reveal nuanced TF occupancy behaviour and shed light on transcriptional regulation in health and disease. In small cell lung cancer #SCLC PDX models, it uncovered surprising gain-of-function p53, FOXA1 & MYC activity post-chemotherapy – not for ASCL1, NEUROD1, POU2F3 or YAP1 (5/7)

How is DynaTag better than other technologies?
⚡Preserves weak/transient TF binding without signal loss
⚡Better signal-to-noise & resolution
⚡Works for all TFs (high and low DNA-binding affinity) & histone marks
⚡Low-input needed, bulk or single-cell, scalable to multi-cellular systems (4/7)

🤔 How to capture nuanced TF-DNA interactions?
💡 Enter #DynaTag: ‘Dynamic targets and Tagmentation’ captures transient TF-DNA interactions that standard CUT&Tag misses.
The trick? Sample prep under physiological salt stabilizes specific interactions without promoting untargeted tagmentation 🧂 (3/7)

❗TF occupancy mapping is still challenging. CUT&Tag was a breakthrough, but it has limits…
👉 Doesn’t work well for TFs that only transiently bind DNA
👉 These fleeting interactions are often lost during sample prep
That means we’re missing key regulatory events and it’s time for a new method (2/7)

🧪Move over CUT&Tag, there’s a new #TranscriptionFactor mapping method in town.
Our newly developed DynaTag is faster, cleaner, more sensitive than #ChIPseq, #CUT&RUN and #CUT&Tag.
