  • Anatomy of a microscope
  • Objectives and refraction index
  • Cameras and detectors
  • Noise and background, Bit depth and saturation

Registration to the LCI microscopy course 2023 closes on Monday!

It is time to enroll to the yearly light microscopy course run by the Live Cell imaging core facility (30 Jan – 17 Feb 2023): Microscopy: improve your imaging skills – from sample preparation to image analysis’ (6 credits).

  • Check the course schedule to see the course content and testimonies from alumni
  • If interested, you can enrol as a studentPlease read carefully the eligibility criteria and note that the last registration date is the 15th of November.

Additionally, all the lectures (in blue on the schedule) will be publicly broadcasted live on Zoom and accessible to anyone without registration. Even if you do not want to enrol as a student, you can have a look at the and listen to any lecture that triggers your interest. There is no need to register. The schedule and zoom link are on the course page.

The purpose of this course is to enable PhD students and researchers who have already and recently used a microscope to acquire images of fluorescent samples, to improve their microscopy skills.
The course is NOT aimed at training people to use the LCI facility microscopes. The focus is instead on providing the students with enough theoretical and practical knowledge about their OWN sample and their OWN microscope, to enable them to:

1) prepare their sample and formulate their scientific question in a way that is suitable for data extraction from fluorescence images

2) properly use the hardware available in their lab/facility and 3) fully understand each parameter they need to set in the software in their lab/facility.

The aim is to provide the course students with the tools to acquire on ANY wide field, confocal or light sheet microscope, images of their samples that reliably answer their scientific question.

Please help us spread the word. 😃

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 organisms…
    • 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! 🙂

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.

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.

Gisele got the Chan Zuckerberg Initiative grant!!

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!

LCI microscopy course, vintage 2021 :)

The Live Cell imaging facility will run again its intensive light microscopy course in Jan-Feb 2021.

The schedule can be found here.

As usual, all lectures will be publicly broadcasted live. So if you think that a lecture could be useful for you, you are welcome to listen, without registration, by following this link.

Due to the current pandemics, only registered students will be allowed in the lecture room.

The course comprises lectures, workshops, imaging of your own sample, demos… It will run 26 Jan-12 Feb, 3 days/week (tues-thurs) 9:00-17:15.

There are only 16 spots. The course counts for 6 credit points.
The rest of the time (the course counts for 4 weeks) is used for home assignments. Mondays and Fridays will also be used for individual workshops where we image your own sample.

The application process is open now until the 16th of November. Please read carefully the eligibility criteria. You will need to sent me some images of your sample at the time of application. This course is only open to people who already have some experience of fluorescence microscopy.

Microscopy: improve your imaging skills – from sample preparation to image analysis

At the end of the course, the participants will be able to:
1- Describe the difference between wide field, confocal and light sheet microscopes as well as the different types of confocal microscopes and choose which system is most suited to their experiments
2- Pick the best combination of fluorophores for their experiment by matching their spectra with the microscope light source and filters, identify and eliminate bleed-through and cross-excitation problems
3- Explain objective specifications and limitations and choose the appropriate objective for their own experiments
4- Describe how to fix, mount and handle their sample in a way that is optimal for imaging
5- Find their sample and the area of interest without bleaching it
6- Adjust the condenser for proper DIC imaging (Koehlering)
7- Explain how to set the following parameters on a wide field, a confocal or a light sheet system to best match the requirements of their sample and reliably answer their scientific question: resolution, pixel size, averaging, scan speed, illumination power, detector gain and offset, camera readout rate, exposure time and camera binning
8- Explain which applications require a hardware or a software autofocus, a spectral detector, a resonance scanner, two-photon or super resolution microscopy
9- Explain the advantages in using the automation of a microscope system to collect multidimensional data
10- Explain how to deal with images before publication in scientific journals
11- Describe the imaging requirements for automated image analysis
12- Run an image analysis pipeline on freeware (ImageJ/FIJI, Cell Profiler) designed for their own images and scientific question.

Please spread the word to your colleagues.

We are looking forward to meeting you and your sample! 😃
