Ab-trapping - a peripheral staining artifact in antibody-based microscopy and genomics Antibodies (Ab) are essential for detecting specific epitopes in microscopy and genomics, but can produce artifacts leading to erroneous interpretations. Here, we characterize a novel artifact, Ab-tra...

Excited to share our work on "Ab-trapping," an antibody artifact causing misleading peripheral ("rim") staining in imaging & genomics (IF, CUT&Tag, CUT&RUN). Antibodies fail to penetrate structures, accumulating at the periphery. A πŸ§΅πŸ‘‡

In addition to coming here, we are planning our move away from Slack! Considering Discord or Zulip. Any pros/cons for either of those for us as a group working on open source software for biological data analysis?

Excited to share James Jusuf's preprint:

By integrating Micro-C with SuperRes Live-Imaging we can calibrate genomics&imaging to perform absolute quantification of looping (e.g. this loop is present 3%)

We quantify mESC 36k loops: <loops> are generally rare (2.3%)

Application to speak in the Fragile Nucleosome series Thank you for your interest in our seminar series! We use a variety of different session formats but, in general, trainees can plan for a ~15 min talk + 5min Q/A and PIs can plan for a ~25min talk +...

Do you have a new and exciting chromatin/transcription story that you'd like to share with an enthusiastic audience?

If so, you should apply to give a talk in the 2025 Fragile Nucleosome seminar series: forms.gle/fwMYPFDf4az3...!

We're open to scientists at all stages of their careers!

Beyond genomic weaving: molecular roles for CTCF outside cohesin loop extrusion CCCTC-binding factor (CTCF) is a key regulator of 3D genome organization and transcriptional activity. Beyond its well-characterized role in facilitat…

Closing 2024 with a review! Excited to share the latest (short) review from our lab, written by amazing Ramani/Narlikar lab grad student Aaron Corin in collaboration with @elphegenoralab.bsky.social! We focus on CTCF's myriad functions beyond regulating loop extrusion; tons to dig into!

After a month of hard work to create a pool of over 50 fantastic mentors, we have opened the call for mentee applications!
If you are an early career researcher and need help navigating the career path (be it academia or industry, or anything else), see if there is a mentor for you and apply!
