Proof of principle. A critical step in many projects...

-> Here's the first data from an AMS-AGY objective. Without building the whole instrument, it showed that a tilted Snouty (Frustum) objective can avoid the resolution lost in an oblique plane microscope!

Our snouty v3 (AMS-AGY v3) objective arrived today! Looking forward to getting it installed on our single objective light sheet system very soon...

How has AI changed CAD? Can AI now reliably generate 3D parts, assemblies and drawings? I'm interested to hear about new tools, workflows and experiences ;)

-> Here's a series of enclosures I designed years ago for housing custom lab equipment. Can AI CAD just generate this automatically now?

Sharing: A simple automatic liquid dispense arrangement (SALDA) for timelapse microscopy.

-> A SALDA enables accurate and repeatable liquid perturbations during timelapse microscopy and avoids environmental disturbance and vibrations from the user!

Pro tip! As much as I like the 55deg #Snouty microscope configuration (previous post) it's hard to align and keep aligned!

-> Consider using pre-designed O2-O3 optomechanics and an eyepiece to help avoid collisions during the set up!

I'm excited to be hiring an intern to develop new fluorescence-based assays for alpha synuclein aggregation at Calico during summer 2026 😃 🔬

If you're a current PhD student who loves microscopy, unnatural amino acids, and/or synuclein biophysics, please apply!

The ASI machine shop made a nice replica model of the AMS-AGY v3 objective for us to have in the #CellBio2025 booth. The first of the real ones will be ready by the end of the year.

Hands down my favorite #Snouty microscope configuration!

-> The air objective with a 55deg light-sheet. It's not the highest resolution version, but the convenience of the air objective, the large field of view and the steep sectioning of the light-sheet make it a pleasure to use!

Fast, gentle, 3D and high resolution makes miOPM ideal for timelapse microscopy of complex neural networks!

-> Here's a unique iNeuron-iAstrocyte coculture imaged by github.com/gav-sturm and carefully prepared by @kunalshroff.bsky.social from the @kampmann.bsky.social lab.

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?

Another huge advantage of miOPM is that it's gentle! A light-sheet microscope that's compatible with standard slides and multi-well plates!

-> Here we show 3D mitochondrial membrane potential in mammalian cells (GFP/RFP for mito, Cy5 for DNA). The cells move around freely!

A huge advantage of miOPM is 3D imaging with an air objective (previous post), but for extra depth you can also use a water objective!

-> Here's mouse alveolar organoids with Muc1 AT2 cells (green), TOM20 mitochondria (blue), RAGE AT1 cells (gray) and DAPI (magenta).

Playing around with how to represent volume in #Snouty light sheet data. Here is a dividing hiPSC with endogenously tagged histone in all three orthogonal projections. Bluer is further away. If anything, it distracts from politics.
