Seminar on how to directly label your primary antibodies

Skip the secondary, part 3! 😀

The LCI will host a seminar about GlyCLICK, a new way to directly label primary antibodies and stop using secondaries: 6th of November at 13:00 in the Lipid seminar room in Neo, KI Flemingsberg. The seminar will be broadcasted live. Here is how to find us and here how to follow the seminar online.

Everyone agrees that it would be great to be able to label our samples without using secondary antibodies.

  • less animals killed
  • shorter and cheaper protocols
  • no problem with isotype cross-reaction
  • no problem with secondary species when using many antibodies at once

There are many kits to label primary antibodies directly with fluorophores. The main disadvantage compared to primary/secondary stainings is that direct labels are often weaker because the final primary/fluorophore ratio is too low. Using an amplification method like TSA (Tyramide Signal Amplification) leads to a loss of resolution.

Over the years users at the LCI have tried this kit, this kit and this one. They gave mixed results depending on the antibody but we keep looking! Come to the LCI seminar about a new direct labelling technique that uses Click chemistry.

Apply now to the LCI microscopy course 2020 :)

It is now time to register to the LCI intensive microscopy course (Jan/Feb 2020). Check out the course schedule.

Loads of fun workshops, informative lectures, intense discussions and our popular Student Imaging Challenge workshop where students get direct feedback on how to improve their own sample preparation/experimental design.

We always run two courses in parallel:

  • the full course (#2870, 6 points, apply here) where students attend all activities
  • the theory only course (#2871, 4.5 points, apply here) for students who only attend the lectures

As usual, all lectures are public and broadcasted live so you are welcome to just show up (how to find us) or watch remotely (how to connect) without registration.  Check the program as it may be updated in case of (unlikely) last minute changes.

We welcome your feedback about the quality of the webinar and the content of the lectures.

Party time at the LCI! :D

On the 10th of October, the Live Cell Imaging facility will have an open house and a little party to celebrate loads of great stuff:

  • The LCI turned 10 years old this year! 😊
  • We got a wonderful light sheet system earlier this year. It is high time to give it a name and splash it with a bit of champagne!
  • Gisele Miranda from Scilife/BII has joined the LCI team to help our users with image analysis
  • We got a great server/analysis capacity set up by the KI IT department

Wow! What a year! 😃

Please come and celebrate with us! If you do not know what our microscopy facility has to offer, it is time to be curious and pay us a visit.

  • Open house: drop in between 9:00-11:00
  • Baptising of the light sheet system and celebration of Gisele and our shiny new server: at 11:00

All this will happen on the 10th of October (next Thursday) at the LCI facility, on the 7th floor of Neo at KI Flemingsberg. Here you can see how to find us.

Please help us spread the news! 😊

Call4Help: fast-track help with your image analysis project!

BII (BioImage Informatics, the great image analysis at SciLife Uppsala) and the LCI facility will run a new Call4Help on the 4th of September.

Anyone who is stuck with image analysis and wishes for quick help to build a pipeline should apply. You don’t have to acquire the images at the LCI. Anyone can apply.

How does it work? You first upload your images and a little explanation text. A few days later, we all meet virtually in a Zoom chatroom for a quick (30 min-1 h) online session. You get comments, suggestions and help with building a Fiji or CellProfiler analysis pipeline tailor-made for your images.

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! 🙂

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!!

Call4Help: The image analysis help you have always dreamt of, totally for free!!! ???

After the success of the previous Call4Help session in February, BII (BioImage Informatics, the great image analysis at SciLife Uppsala) and your favorite microscopy facility (we hope) will run a new Call4Help next Tuesday 2nd of April.

Anyone who is stuck with image analysis and wishes for quick help can apply.

These are 100% online sessions (we ‘meet’ in a Zoom chat room) where you submit your images and a little explanation text in advance and you get suggestions for 30 min and an analysis pipeline all done for you (Fiji, CellProfiler, Ilastik, QuPath, KNIME)!

If you are interested, please apply as soon as possible (sorry for the late announcement).

First SciLifeLab BioImage Informatics call4help zoom session

On the 14th February 2019, 10:00 – 12:00 the SciLifeLab BioImage Informatics Facility is organizing an online support session on BioImage Analysis (“call4help” session).

How does it work?

Each selected participant gets a 15 min slot. You have 5 min to present your problem. It is mainly about showing the scientific context, representative input images, describing desired output measurements, and giving a brief statement about what was done before. The remaining 10 min we will brainstorm together on the possible solution(s), discuss tools, techniques, etc.

The Bioimage Informatics Facility can provide further support, if needed. We are happy to announce that Sylvie Le Guyader, Live Cell Imaging Facility, KI, Huddinge, is joining the session as microscopy expert.

Call4Help format

The call4help format was initially developed by ScopeM, ETH Zürich.

The LCI facility has moved to Neo! :)

That’s it! We have done it! We have moved to Neo! 😀

The trip to Neo (just next door to Novum) started at the end of 2015! 2 years and lots of planning meetings later, all the companies involved (mostly Bergman Labora and Zeiss but also Alveole, La Vision Biotech, MMI and Andor) started dismantling, moving and reassembling our 7 microscopes on the 4th of December. Now, one and a half month later, everything is nearly done! Exciting! 🙂

LCI microscopy course 2017 is here!

The Live Cell Imaging facility will soon run its intensive microscopy course 17th Jan-9th Feb. Loads of fun workshops, informative lectures, intense discussions and our popular Student Imaging Challenge workshop where students get direct feedback on how to improve their own sample preparation/experimental design.

The full course (#2870) is full but the theory only course (#2871, 4.5 points) has unlimited space so you can still apply (mail me) until the 13th.

As usual, all lectures are public so you are welcome to just show up without registration. The full program is on our our course webpage and instructions on how to find the Green seminar room can be found here. The program will be kept updated in case of (unlikely) last minute changes.

Additionally this year, we will do our best to broadcast all the lectures so that you do not need to physically come to Flemingsberg to listen to your favourite topic. Instead, just follow check the schedule on our course webpage, find out which lecture you want to follow and follow the LCI webinar link. We welcome your feedback about the quality of the webinar and the content of the lectures.
