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...

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%

The longer we have worked on and refined this #microtubule - based model of #neurodegeneration, the more convincing it becomes. It is the fruit of 20 years of work. If you are interested, join my THE CYTOSKELETON OF NEURONS AND GLIA online talk this Thurday: ncytoskeleton.wixsite.com/webinars

Your yearly reminder to acknowledge the core facilities you use and their staff scientists in your papers. These scientists are a crucial part of the scientific ecosystem and to continue to exist they need tangible credit for their work. Plus their associated expertise adds credibility to your work.

Polypropylene. Autoclavable. Reusable. Fairly clear. One more polystyrene lab consumable eliminated? Let's find out! a.co/d/667XVjL

New plasmid collection available from the Bas Teusink Lab! The plasmids in the Botman-Teusink Yeast FP Collection enable constitutive overexpression of fluorescent proteins and tagging of genes of interest in yeast. www.addgene.org/depo...

I want to do a project where I go a little deeper on scientific papers that get picked up in the news. If you see anything that might be a good candidate, hit me up!

ATTENTION (PLEASE SHARE) If anyone has or knows of any positions that might be appropriate for the NIH staff members who were terminated, please post the information in this thread. There are lots of talented and accomplished people who may be looking for new opportunities.

Come learn microscopy with us by the sea in May!

Is it possible for a FP to bleach much faster in point scanning confocal microscopy than in spinning-disc confocal ? To the extent that it's barely usable in point scanning but works fine in SDC? A user seems to have observed this with an RFP variant - (and I tested 3 point scanners...).

Biomedical research uses a lot of chemicals. Essentially every procedure in molecular biology, biochemistry, or genomics involves the use of chemicals including solvents, toxins, and carcinogens. You can't just dump these things down the sink when you're done with them!!!

For those who aren't biologists: This is a biosafety cabinet. Every biomedical research lab in the country has one or more of these bio safety cabinets. They use air flow to protect cells from contamination by bacteria and fungal spores while you are working with them.

Cuts in NIH research grants will have a lasting negative impact on science and medicine in the U.S. Grants will continue to fund specific research costs, but essential infrastructure like labs, advanced equipment and support staff are crucial for groundbreaking work.

My main PhD paper is on bioRxiv! 🥳 We used motor-PAINT, expansion microscopy, and live-cell imaging of StableMARK to map out how the microtubule cytoskeleton reorganizes during neuronal development. www.biorxiv.org/content/10.1...
