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! 🙂

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

BII webinar about a great tool! TissUUmaps

The BioImage Informatics facility at Scilife organizes a new presentation on free and open-source tools: TissUUmaps, a browser-based tool for GPU-accelerated visualization and interactive exploration of millions of datapoints overlaying tissue samples.

Users can visualize markers and regions, explore spatial statistics and quantitative analyses of tissue morphology, and assess the quality of decoding in situ transcriptomics data. TissUUmaps provides instant multi-resolution image viewing, can be customized, shared, and also integrated in Jupyter Notebooks. TissUUmaps was created in collaboration between BIIF and the Wählby lab. You can read more about it and test the software on its web page: https://tissuumaps.github.io/
During the seminar, we will go through basic usage of TissUUmaps: installation, loading images, markers and regions, change visualization settings, and how to load / save / share projects. The webinar will be given by Christophe Avenel and will take place on March 3rd, 09:00-10:00 (instead of our normal Call4Help session). There will be time for questions and discussion, so we hope this event to be very interactive. Please register here.

Listen to the lectures at the LCI facility microscopy course!

Starting from next week, the Live Cell Imaging core facility at KI will run its yearly microscopy course.

All the course lectures and some workshops will broadcasted live on Zoom, free of charge and there is no need to register.

BII webinars and Global Bioimaging lectures

Lots of interesting courses and webinars about microscopy in these corona times. The BioImage Informatics facility at Scilife will present how useful it is to build imaging pipelines with Fiji/imageJ.

April 6th, 10:00-11:00: “ImageJ/Fiji – Make Your Own Macros – Overview”. This is not to teach how to script but to give you an overview of the scripting possibilities in ImageJ/Fiji. Please register here.

Version 2.0 of TissUUmaps is now released: TissUUmaps allows fast interactive display of tissue slide images and uses an overlay to display any sort of marker data on top. Be it spatially resolved gene expression, per cell data, or regions of interest. TissUUmaps is developed in the Wählby-Lab, with involvement of BIIF, and was first published in https://doi.org/10.1093/bioinformatics/btaa541.
Try out TissUUmaps and interact with a in-situ-sequencing dataset on a brain slice!

Congratulations to our dear in-house image analyst Gisele Miranda who got the prestigious Chan Zuckerberg Initiative grant in December! 🙂

Gisele got this grant thanks to the fruitful collaboration between the BioImage Informatics facility at Scilife and the Live Cell Imaging facility at KI. We are delighted for her and for all the LCI users as this will allow us to keep working with Gisele for many years.

Congratulations Gisele! Very well-deserved! 🙂

Look at what CZI has chosen as their symbol of Science: a microscope!

From Images to Knowledge virtual workshop

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.
