Beware the SPY488-FastAct rollercoaster!

We teamed up with CSR Biotech and their incredible MI-SIM microscope to drive you through the intricate actin network of live COS7 cells stained with SPY488-FastAct.

I used to work with 13C too, lots of fun!

Spatial barcoding reveals reaction radii and contact-dependent mechanism of proximity labeling - Nature Chemical Biology A DNA nanoruler platform enables precise measurement of the labeling radii of TurboID and APEX2, uncovering their contact-dependent mechanisms. These findings redefine the enzymology of proximity labe...

Proximity labeling users: check out this study by @zhixingchen2.bsky.social and Peng Zou, which establishes how much contact-dependence vs. diffusion is responsible for biotinylation — tl;dr TurboID has a much smaller effective radius! www.nature.com/articles/s41... 1/2

Thank you Jeremy for the promotion😀

New paper from @zhixingchen2.bsky.social's lab!

It turns out that, in addition to its very low phototoxicity, PKmito Deep Red (PKMDR) directly reports on mitochondrial membrane potential (MMP) in live cells through its lifetime!

Thank you Mike for the host and the discussions! looking forward to future collaborations!!

Congrats and thank you for using PKMito!

🌑Goodbye bleaching, hello brightness! ☀️

We're thrilled to introduce two new Halotag ligands featuring @zhixingchen2.bsky.social fantastic photoresistant BD-dyes!

✅ Highly photoresistant, no photoblueing
✅ Outstanding brightness
✅ Cell permeable
✅ Outperform best in class fluorophores

Check it out at PNAS today. Thank you Alexandre for the collaboration!!

PK Mem probes offer long time-lapse imaging of cell membrane dynamics. Made possible by
Jing Ling, Yitong Liu, and all the collaborators!

Thank you Shinya for the invitation! Very much looking forward to this trip!!!

🔔🧪 I'm deeply saddened by the passing of Michael Sheetz, a true pioneer in #mechanobiology.
I'll always cherish our lovely times in NYC, Singapore, Zurich, and Sydney. My heartfelt condolences to his family and friends in this difficult time.
So long, Mike 🥺😔

Oh magazine maker, let us transfer our pretty papers to her, instead of nature communications.

Thank you for sharing this touching piece!

How and when to measure mitochondrial inner membrane potentials The scientific literature on mitochondria has increased significantly over the years due to findings that these organelles have widespread roles in the onset and progression of pathological conditions such as metabolic disorders, neurodegenerative and cardiovascular diseases, inflammation, and cancer. Researchers have extensively explored how mitochondrial properties and functions are modified in different models, often using fluorescent inner mitochondrial membrane potential (ΔΨm) probes to assess functional mitochondrial aspects such as protonmotive force and oxidative phosphorylation.

Mitochondria vibes only! Want to measure the inner membrane potential but unsure how or when? This review breaks it down! From protocols to pitfalls, get the tools you need to decode cellular powerhouses. ow.ly/Ejj050UsK7Y

I always tell this "discouraging" story to the grad students on my class...

Thank you for choosing PK Mito!

Thank you Christophe for the promotion!!

How proximal is proximity labeling❓ Using DNA nanorulers we found that TurboID/BioID are largely contact labeling, while APEX2 also bears a major contact labeling pathway in parallel with diffusive labeling.
