Direct label of primary antibodies with the FlexAble kit

Some of our users have tested the ProteinTech FlexAble kit to directly label primary antibody and they are very happy so we thought we should share! 🙂

It only takes 10min to label the primary. It saves time for the sample staining procedure and it saves cute animals when one stops ordering secondary antibodies! 🙂 In the hand of our users, the images were as bright or brighter than the same labelling with primary + secondary.

And you can ask for a free sample to test! :):):)

 

Open house at the LCI facility on 24th of September

Dear microscopy enthusiasts,

The Live Cell Imaging core facility is happy to invite you to a microscopy event on Tuesday, 24th of September.

You will have the opportunity to see Nikon ECLIPSE Ji Smart microscope in action!!!! A fast and easy to work with benchtop microscope with many ready to run experimental assays, AI powered automated imaging and instant image analysis!!!!

Free online Microtutor course about fluorescence microscopy

Dear everyone

Microtutor Live will soon start its first flipped classroom version of its online Fluorescence microscopy course. I am happy to be one of the instructors for Europe! See below more info and how to apply! 🙂

Fluorescence Microscopy is a common technique in biological research, yet few researchers receive formal training on how to use it effectively. Microtutor, an interactive and free educational website, addresses this gap by offering self-guided courses on microscopy fundamentals. Students enroll themselves and work through the course at their own pace. Since the release of the first course on fluorescence microscopy in June, >600 students from all over the world have enrolled.

This fall, there is now going to be a special Microtutor LIVE version of the fluorescence microscopy course that includes instructor support instructor support. In this version, the students are assigned virtual course content each week to go through on their own, and then meet weekly with instructors over Zoom for Q&A. They can also attend virtual guest lectures each week, which will cover applications of the content. At the end, students can submit an optional individual project in the form of a microscopy experiment proposal to receive a certificate of completion for the course.

Students can learn more information and apply to join here

The LCI core facility is now a member of Eurobioimaging!

Good news! The LCI facility is now part of the Swedish Eurobioimaging node! 🙂

This means that you can apply for funds to come and get trained, do some job shadowing or image at the LCI core facility!

The Swedish Eurobioimaging node is even partner in special European funding programs for Agroecology, and Cancer research.

We are looking forward to welcoming you to our facility! 🙂

 

International microscopy student mixer on March 17

Participate to a online evening of fun activities with other students who use microscopy across the world! 🙂

Scan the code to register and choose Other for microscopy society.

The LCI open microscopy course starts on Monday! :)

Dear all

It is my pleasure to invite you to follow the LCI facility microscopy course Microscopy: improve your imaging skills – from sample preparation to image analysis.

The course starts next Monday (29 Jan) and runs until the 16th of February.

As usual, all the course lectures are broadcasted live on Zoom. It is free of charge and you do not need to register.

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 more knowledge could help them.

Here is a selection of what we will talk about:

  • Optics and image formation,
  • Anatomy of a microscope
  • Objectives and refraction index
  • Cameras and detectors, Noise and background, Bit depth and saturation
  • Sample preparation, Immunostaining, Clearing and expansion
  • Resolution and contrast, Nyquist sampling, Microscope settings
  • Data handling, OMERO.figure, Requirements for image analysis, Colocalization
  • Image processing and analysis

Check our course webpage to see the course schedule (Broadcasted activities are in blue) and the Zoom link. Scroll down to read the kind testimonies of our dear students! 🙂

Here is the course syllabus.

For those who are on a far away time zome, we record all the live lectures and post them every evening on the LCI facility YouTube channel! 🙂

We hope that you will enjoy the LCI facility microscopy course!

Kindly forward to anyone who might be interested.

Spatial transcriptomics in Flemingsberg!

Spatial transcriptomics techniques are booming! It is now possible to identify where RNAs are located within a tissue! At the LCI facility, we routinely image samples labelled with RNAscope. If you use RNAscope, you might be interested in this workshop where you will learn how to label thick samples with RNAscope, and this symposium about automated RNAscope.

Additionally, we can now offer the 10x Genomics Visium technology on the South Campus, as a collaboration between 4 core facilities in Flemingsberg: LCI, FENO, SICOF and BEA core facilities!

Here is the workflow:

  1. We discuss your project and advise you for the preparation of your sample.
  2. You cut your sample and optimize the antibody or H/E staining yourself, under the guidance if the LCI staff to best preserve the RNAs.
  3. You image your tissue sections at the LCI facility.
  4. You transfer your section to SICOF who tags the RNAs and amplifies the library, using the 10x Genomics Visium technology.
  5. The library goes to BEA for sequencing.
  • Section size: max 6.5×6.5 mm or max 11×11 mm
  • Human or mouse
  • Paraffin-embedded or fresh-frozen
  • Labelled with H/E or fluorescent antibodies

Come and talk to us about your Spatial Transcriptomics project!
