New paper from the @rouxlab.bsky.social on Nature Communications! We study how membrane tension is spatially organized in cells. Using the mechanosensitive probe Flipper-TR to visualize tension across the plasma membrane of adherent cells and to dissect the conditions needed for a gradient to happen

In our new #Preprint, we pilot a revolutionary new idea: no supplemental data (it has 21 figures, though):

Multiplexed imaging of G-proteins and ERK activity upon activation of CaSR
We have previously shown that the calcium sensing receptor (CaSR) activates different G proteins and second messengers in single cells, and that GPCR and G protein-mediated ERK activity can be highly ...

Thank you @prelights.bsky.social for highlighting HAK-actin!

HAK-actin is a great tool for ExM actin staining.

Quite a busy day on #Bluesky !
Been a while since we have been #preLight -ed !

Discover HAK-Actin if you haven't already ;)

Cool, the HAK-actin preprint was showcased by @prelights.bsky.social
A good reason to read it if you haven't yet 😜

New preprint 🥳! We made photoclickable HaloTag ligands to precisely control protein labeling on living cells. With it, we can do some cool multicolor stuff. Huge congrats to Franzi and all co-authors! Check it out 👇

Cool paper using a new JF derivative to map synaptic proteins. And AI didn't like the generality of our general synthetic methods section (that we've used for years), so we expanded them from 2 succinct paragraphs to 1.5 gloriously unreadable pages. Better than Ambien. www.nature.com/articles/s41...

Went looking for quartz over the weekend. I was lucky to find a nice untouched pocket with well-formed crystals (after 3h of search!). The first picture shows the cluster in situ within the crack and the other one shows the same crystals as a detached piece.

Happily surprised by the quantity given the very moderate bloom in spring.

👉🦠Interested in bacterial membrane tension?

Our membrane tension probe Flipper-TR is a top tool for the job!

A new article in @pnas.org demonstrates how Flipper-TR efficiently stains bacterial membranes and responds to various stimuli altering membrane tension.

Live cell ACTIN imaging has never been easier with SPY650-FastAct_X!

1. Add the probe to the cells
2. Image 1h later

SPY650 is highly suited for STED imaging. The image shows a confocal/STED comparison of the fine actin mesh in a live HeLa cell.
