90% of you probably don’t need to read this.
But maybe some of you are curious & 10% will feel seen. Or a little less alone. This isn’t about seeking sympathy.
It’s about sharing something hard to say out loud;
partly to heal, partly in case someone needs to hear it too. (1/3)

It was a really fun couple of weeks in the lab !
I also very much enjoyed being in full handle of the #Zeiss 3Dsim scope provided generously for us to explore the various samples.

Over the last two weeks the Dudin Lab expanded two-fold and it’s been a blast!
We are hosting a group of amazing visitors that stopped by with their own species and samples to get started with expansion microscopy.
It was a ton of fun, very much looking forward to pictures to come ❤️

This is the cover proposal I made for our recent paper!
It’s Pyramimonas diskoicola — a very beautiful green flagellate and one of those cells that makes you stop and stare for a while.
I tried to capture its shape, symmetry, and general vibe :)

Are you staining DNA in your ExM samples?
We have awesome news for you! All our 6 SPY-DNA probes work beautifully well with the U-ExM protocol.
You can now tune the color of the DNA channel to your needs, according to the fluorophores on your preferred antibodies.
