And my project on how to extend the field of depth in inverted fluorescence microscopy workflows for expanded tissues is now out out! 😁 More exciting things to come out of my PhD! 🤩

Microscopy Bat signal! I want to compile a list of biological samples that demonstrate microscope capabilities, including the reagents to generate them. Please send me anything you know of!! Beads are great for QC, but there's a different teaching benefit with biology. 1/n

Just 4 days until the start of I2K and its 33 totally free image analysis tutorials and events! Please share with your "home networks", especially early career researchers - the videos will be amazing and high-impact no matter how many people attend live, BUT (1/x)

Broader #bioimaging and #microsky people - anyone have any suggestions for sources of ~0.25mm non-cytotoxic double sided adhesive sheets?

Has anyone had this problem? A hydrophobic water objective? The objective is great but we struggle to keep the water on the lens... -> Maybe a solution is to paint a circle around the nose with a 'hydrophobic barrier pap pen" (link below). Has anyone tried this? www.fishersci.com/shop/product...

Ever wondered if analyzing your images by using intensity Z-projections impacts your data? Happy to announce my guest article in Microscopy & Analysis on that topic. It's a very short read but worth for everyone dealing with image analysis! buff.ly/KJ147tI #Microscopy #ZProjection #ImageAnalysis

My new ImageJ / Fiji toolkit is out 🔥! The goal is to make image handling & visualization easy, with an intuitive interface! Install it on Fiji with the "Image Viewer" update site #microscopy #ImageJ #FluorescenceFriday #microscopyMonday imagej.net/plugins/imag...

One of the most useful resources for anyone who uses fluorescence methods.

Do you like building novel optical microscopes to answer complex biological questions? How about doing that as part of one of the world’s most unique and vibrant research and education communities, which is incidentally located in a beautiful seaside New England village? 🐙🌊🔬

Not all colormaps are created equal. Notice the nonlinear brightness scaling in two very popular ImageJ LUTs! (Glow & GFB)

Another aspect to consider is how much colors are saturated, depending on the LUT, the screen type and settings it can make a huge difference on data readability. Green Fire Blue is popular but really saturated

Periodic reminder that the fluorescent compound in mammalian cell culture media, such as DMEM, is riboflavin (not phenol red)

Does anyone know a database where let say I have 2 proteins: Integrin and FAK, I can find out what motif/sequence of amino acids mediate their interaction? Thank you. #questions #academia

I’m happy to share some plugins I’ve been developping this summer: "Channels and Contrast" and LUTs Manager! I can’t find new bugs and ideas by now so I need your help to please test them in your machines and report bugs, feedbacks and ideas! forum.image.sc/t/looking-fo...

#GEF25 the expansion microscopy community would benefit from high NA, long working distance water objectives. Who's working on these? What's out there?

Now out on bioRxiv. 🥳My research on #cytokinesis, averaging thousands of #ExM images🔬, creating a dynamic atlas of cytokinesis 🦠⏳. Here's an animated sneak peek of what we found. Better resolution on bioRxiv😄 #PSFoftheGIF

#FluorescenceFriday: getting ready for #GEF25, playing with Ciarán's stunning ExM data

Bringing some more ExM to #FluorescenceFriday with what appears to be a frustrated cell division in fibroblasts. More details in Alt-text.

The WB-ExM protocol described here works with.... every sample we tested! Here a 3do quail embryo (white= pan-protein; red=MF20) www.biorxiv.org/content/10.1...

Halfway to I2K is BACK, friends of all kinds! Last year, 650 people attended 30+ TOTALLY FREE image analysis workshops of all kinds, across many timezones. If you make image analysis software and want to teach it, workshop submissions are open now! We'd love to have your tool highlighted.

@joachimgoedhart.bsky.social and Flurescent protein colleagues--help! With advice from imaging freinds, we tagged a protein of interest with "tagRFP", which we now know from its protein sequence and digging is a derivative of eqFP578 from Entacmaea quadricolor. We want an antibody to it but 1/n

Time to add some ExM to #FluorescenceFriday ! Sample description in alt-text.

Alright I have something useful for you to do. Think of any teachers and librarians you know. Do they know about Skype a scientist? Our program matches classrooms & other groups w/scientists for virtual Q&As. It’s free! They can sign up here! www.skypeascientist.com/sign-up.html #Edusky #StemED

After seeing @miguelcmestre.bsky.social @lancasterlab.bsky.social @jamesdmanton.bsky.social 's paper this week on deep and accessible ExM imaging with cerebral organoids, I think it's a good time to repost this Starter Pack of Expansion Microscopy people! go.bsky.app/Qxks9WD

We present a simple method to easily increase the imageable depth of an expansion microscopy gel on a typical inverted microscope ten-fold, using some carefully placed FEP film and a water dipping objective lens:

🚨Publication alert🚨 My first, first-author paper is now out in @natphoton.nature.com! Our paper describes an iterative spectral unmixing algorithm and eight-channel camera-based hardware we developed enabling unmixing of low SNR live-cell data at video rates. www.nature.com/articles/s41...

In 2019, Anna Jost & @jencwaters.bsky.social reviewed best practices for validating quantitative #microscopy methods & discuss strategies to avoid unconscious bias in imaging experiments rupress.org/jcb/article/... 📕 In #Reproducibility & Best Practices in Cell Biology: rupress.org/jcb/collecti...

OK--fluorescent protein friends. We want an antibody to TagRFP that works in immunofluorescence. Any suggestions? Re-post please

We have a user that wants to set up a multipoint tiling experiment on our Nikon Spinning Disk and it will take a few hours. We need to use the Nikon water objective, which evaporates. Suggestions to stop evaporation or other immersion?

Hello microscopists!! Help needed - does anybody know of any good Mn2+ indicators that are good in live cell microscopy assays ? Never worked with them before and not sure if there are any reliable & affordable ones out there..? Reposts appreciated 🙏🙏

Can anyone recommend a service where I upload 3D models of simple machine parts and they mail me the CNC'ed results? Something like Osh Park that does small batches but for machine parts? I feel like I saw something about this recently but can't remember which platform I saw it on.

Who would have thought inverting colors would be so tricky ? jordan.yoonbuck.com/post/contras...

I'm trying to help a high school teacher get an old Nikon E600 running for fluorescence imaging. Does anyone know if there are specs floating around for printing an adapter(s) that would allow it to take a standard LLG? She really wants to avoid having to go back to using Hg lamps.

Seeking recommendations for good price agarose for gels!! The Invitrogen Agarose I've been using for years is now $705 for 500g with internal discount, and I see no reason not to explore other options 🙈. 🧪🧬🧫

The goal is plainly and literally to cut the number of people involved in basic science in the US by 70%
