Getting to know more about bacterial toxins under Open Science and FAIR Data principles.

Iron is essential for growth of Tetrahymena in axenic media (prey-free)🧪. Last time we made our stock solution was three years ago. How do we prepare it and store it? The details are now published in @protocolsio.bsky.social under www.protocols.io/view/fecl3-s... and just in time for a new lot 🥼🫡

FeCl3 solution for NEFF Media

For axenic growth of Tetrahymena thermophila in the lab, NEFF media requires a final concentration of 33 µM (see Tetrahymena Stock Center (RRID:SCR_008362)). To guarantee that...

Buffer is ready. Hmm. can I sterilize it in the autoclave? When the answer is no, the next best option is to do a sterile filtration. It's not a big deal, but it's easy to do it wrong. Here is our protocol! 🧪 Sterile filtration of liquid solutions  www.protocols.io/view/sterile...

Sterile filtration of liquid solutions

Some liquids are not suitable for autoclaving but need to be sterile for use. Here we describe the process of filtering any solution to achieve sterility (at least removal of or...

Nothing more annoying than preparing buffers, but extremely necessary if we want to mate ciliates. Here is our protocol for the 1 M Tris-HCl pH 7.5 for Tetrahymena mating (Stock solution) www.protocols.io/view/1-m-tri.... We hope it will be helpful for the community! 🧪 🤲🏻🥼

1 M Tris-HCl pH 7.5 for Tetrahymena mating (Stock solution)

In this protocol we specify the steps needed to create a 250 ml stock solution of 1M Tris-HCl solution used for the preparation of Tetrahymena thermophila cells for mating. The...

I love to help to solve challenges that come up in the lab, and yesterday I was able to link our protocol for veggie NEFF media in a personal communication (www.protocols.io/view/veggie-...) while discussing differences in flow cytometry results. Life is easier with @protocolsio.bsky.social 🤪🧪

Veggie NEFF media for Tetrahymena thermophila

The ciliate Tetrahymena thermophila has been a research organism used by a great community of scientists including biologist, geneticists and toxicologists. T. thermophila is a...

We still have places in our Machine Learning School. Anyone in natural sciences or medical background can take part. You just need to be in Munich between the 9th and 12th of December and have the full day available! You will learn the basic of python and will apply it to create your own ML model 🧪

Two more protocols out in @protocolsio.bsky.social. Little by little we can build upon each one to get everything ready for the big ones. This time we have a buffer solution for Quality Control of the AlamarBlue stain, and a classic: Gram staining www.protocols.io/view/gram-st....

Gram staining

This protocol is performed as described by the ASM (American Society of Microbiologists) in their document Gram Staining Protocol, 1981. Our aim is to include all instructions t...

Question to the community 🧪: in the last 4 years, I have tutored PhD students from other labs and institutions. Too many have had a lot of problems because of bad PIs, and I do mean really bad scientist and people. Some are under investigation. How can I warn future students about them?

Curious about how you can use your data in the 21st Century? Come and learn with us between the 9th and 12th of December about Machine Learning (mlschool.rostlab.org). After you learn the basics of python, we dive into tidy (FAIR) data, and your first model under best practices in the field. Free!!!

Machine Learning School for Toxinologists 2023

Machine Learning School for Toxinologists, Bioligists. We will teach the basics of machine learning with biological data.
