Cool stuff one can do with the LCI Primo

At the LCI core facility, you can use a machine called Primo to micropattern/print proteins at the bottom of a microscopy dish and enable real time imaging of cell-protein interactions.

Now we learnt that we can even micropattern lipids and antibodies on microscopy dishes to image how cells interact with these molecules! This can be done with any pattern and even in multiwell plates! ๐Ÿ™‚

Lipid micropatterning: Here is a cool paper showing how filopodia interact with sourrounding lipids and proteins. They image with Structured Illumination and TIRF, techniques that are also on offer at our facility. ๐Ÿ™‚

Antibody micropatterning: A new way to analyse extracellular vesicles with multiplexed detection of proteins and RNAs at single EV resolution.

Light-seq: Multiplexed, non-destructive spatial transcriptomics of tissues sections using light

Light-Seq is a new pretty cool technique for highly multiplexed sequencing of RNA in tissue sections using light. This technique is highly sensitive, highly spatially resolved and because it does not destroy the tissue, it can be combined with protein labelling (genetic or by immunolabelling).

On one of our single-point confocal/spinning disk/widefield system at the LCI facility, we have a device called Primo (DMD + UV laser) which can be used to run this technique! ๐Ÿ™‚

Let us know if you would like to set up LightSeq at the LCI core facility!

Live demo of the Nikon Mizar TILT light sheet

On the 22nd of September at 10, you get a chance to see and try the latest light sheet on the market: the Nikon Mizar TILT.

    • Easy to use stage top light sheet with only 1 objective
    • Imaging of cell monolayer, cells in gels, organoids in gels, small organismsโ€ฆ
    • Samples in glass bottom multiwell chamber slides
    • Stage top incubator for live sample imaging
    • Advantage of using the TILT light sheet
      • low phototoxicity and bleaching even with high resolution objective
      • excellent temporal and spatial resolution for live samples
    • See here for more info.

This demo is only for a limited time (10 days) and in person only. Please let us know if you want to join the demo and if you want to try your own sample.

Live demo of the Crest spinning disk with DeepSIM

9th of September, 10-12am: Live/zoom demo of the latest microscope acquired by the LCI facility: Crest spinning disk with DeepSIM (new Orion)

  • Ti2 microscope
  • Crest spinning disk (identical to the one on Tweety but with slightly different wavelengths)
  • DeepSIM: SIM is a fast super-resolution technique which is gentle for the sample (less bleaching, less photodamage for live samples) and offers double the resolution of a confocal microscope (down to 120nm resolution), even thick in samples. It is flexible and can be used with any objectives, even low magnification air objectives.
  • No specific sample preparation requirements
  • More information here

For the best experience, join the demo in person at the LCI facility (please apply by replying to this email) but if you cannot make it, you can also listen on Zoom.

The system has been purchased by the LCI so it is here to stay! ๐Ÿ™‚

Please let us know if you want to join the demo in person and mention if you would like to try imaging your own sample with DeepSIM.

The LCI microscopy course 2022 is now open for registrations!

It is now time to apply to the intensive LCI microscopy course Jan/Feb 2022: Microscopy: improve your imaging skills – from sample preparation to image analysis

The aim for this course is to improve the microscopy skills of students and researchers who have already used a microscope to acquire digital images of fluorescent samples but feel that their knowledge is limited.

All the lectures at the LCI microscopy course will also broadcasted live online, free of charge and there is no need to register.

All details about the course including course schedule, how to apply, and how to follow the lectures are found here.

Scroll down to read the kind testimonies of our dear students! ๐Ÿ˜Š

Hope you enjoy the LCI facility microscopy course 2022!

Tweety turned into a power machine!

Our dear Tweety microscope, which was simplest and cutest of all the LCI systems, has muted into our most sophisticated power machine!

On the 24th at 10, we will run an online demo (link below) to show what our upgraded Tweety can deliver:

  • Much larger field of view (from 18 mm diagonal to 25 mm)
  • Upgraded single point confocal on the left side
  • Resonant scanner with 1024×1024 pixels (compared to 512×512 on our other resonant scanners), still the same speed (30 fps) and improved low noise
  • Spinning disk confocal on the right side with bypass to image wide field
  • 2 very sensitive cameras on the right side: one with the very large field of view and 11um pixels for best sensitivity and one with the normal field of view and 6.45 pixels for best resolution
  • Our great Primo is still on the back of the microscope to allow micropatterning of proteins at the bottom of a dish or micromanufacturing of wells in the shape/pattern of your choice
  • 2 wonderful silicon immersion objectives specialized for tissue imaging with automatic correction ring: 20x/1.05 and 40x/1.25

After the demo, the LCI users who have already been trained on our widefield systems can get access to Tweety for free after a mandatory short training.

Please add the demo in your calendar and make sure to test the link ahead of the meeting.

Super-Resolution spinning disk demo at the LCI!

Dear microscope freaks

How would you like to run some gentle live sample imaging with a 60x objective with:

  • an xy resolution of 120 nm without software tricks (or even better after deconvolution),
  • the great contrast of a true confocal,
  • 82 frames per second,
  • or decide to bypass everything, go widefield and image at 100 frames per second with a super large field of view (220×220 um)?

Sounds good to me! ๐Ÿ™‚

For the next 2 weeks you can do that with the new toy on demo at the LCI facility!

The beast is a new sort of spinning disk confocal and is called SoRa (Super-Resolution Optical Reassignment). It is a collaboration between Nikon and Yokogawa.

We even have 2 cameras to compare (Prime95B and BSI from Photometrics).

Oliver Garner from Bergman Labora will give a short online presentation of how SoRa works on Monday (29th) at 13:00. The presentation is done remotely and broadcasted live. You can join the audience from the comfort of your office chair by following the instructions here (please try beforehand to make sure all works).

Interested in trying it? Please contact us.

A dream!!

Great video tutorials for our Primo users and paper on microniches

Hello again

Here you can see very nice video tutorials on the Alveole website and this is a cool article by Viasnoff et al about making 3D microniches with 1 um resolution! And you can do this at the LCI facility!! ๐Ÿ™‚

Confocal endoscopy talk in Uppsala

Interesting seminars in Uppsala. Apparently this endoscope can go inside our bodies and has has tiny objective of only 300um!

They will also present at KI (if you are interested contact Gilles Cestelli gilles(at)maunakeatech(dot)com)

Custom made rotating stage insert

One more cute stage insert for the LCI facility, thanks to Peter Arfert, the KTH workshop wizard and his 3D printing machine! ๐Ÿ™‚
