DIYbio Groningen presents: E A S Y P H O R E S I S!

Inspired by our mission to create Open-source hardware for DIYbio labs, we set our sights on the electrophoresis setup. it was designed and programmed using the amazing open-source software OpenSCAD (highly recommended for anyone who enjoys designing 3D objects). Send the file to the 3D printer… — and a new ready to use electrophoresis apparatus is born!

Gel electrophoresis is one of the most used techniques in any biolaboratory, it is used for the analysis and visualization of DNA and proteins — it is a required step in most experiments that involve DNA manipulations.

Interesting fact:

It took us one evening to design a 3D model of the first ‘beta’ version of EASYphoresis. It costs just a few euro to 3D print, plus some tiny pieces of aluminium foil- and that’s it!

On Friday 17 October, we tested our EASYphoresis for the first time. Together with DJO enthusiasts, we performed an experiment during which we ran a DNA sample and some blue markers in the agarose gel. We also tried to make the equipment more waterproof by using the acetone vapour technique.

The results were:

  1. Our first ‘beta’ version of EASYphoresis worked pretty well, which was not surprising to us as the electrophoresis apparatus is a very simple piece of equipment that requires no special materials or difficult hardware for its work.
  2. What is now missing are an efficient power supply for EASYphoresis and a UV transilluminator that will help us to visualize DNA in the gel.

Do you want to help us in designing and making the missing hardware for DNA electrophoresis ? You are very welcome to join us. We meet every Friday at 19.00, come by and see what we can do together! 😉

~ Autumnal Activities ~

Autumn 2014 has been a very nice period for the DIYbio Groningen community. We ran a number of workshops and we have been carrying out several projects at DJO (de Jonge Onderzoekers, Groningen). One of these is the

Mealworm Project

that we initiated specially for kids and nature lovers who can follow the mealworm life cycle in real-time. The primary goal of the project is to see if we can maintain a colony and harvest mealworms to experiment with entomophagy– a fancy word for bug-eating. The beetles will also be used by two students doing experiments on the learning behaviour of insect as part of their profielwerkstuk. (Think: conditioning with electroshock!)

A small mealworm nursery was created together with DJO participants and should do a good job at giving us some hands on experience with these critters. We started out with 1 kg of live mealworms, many have already transformed into pupae and beetles- lets see if we can keep a colony going.

Participants have already done some experiments to see if the bugs are cannibalistic (they are..) and there are some very good ideas as to how to make them taste less bitter.

After some more testing we will release our secret recipe!

Strawberry DNA – Extract it Yourself!

A few weeks ago, we organized another workshop for DJO visitors called ‘Strawberry DNA – Extract it Yourself”. Participants of different ages learned some basics about DNA and they performed simple experiments on the DNA extraction using only some household chemicals. It turned out to be an active and colourful evening.

Strawberry DNA ExtractionIf you would like to extract DNA from strawberries at home, take some salt and soap, mix it with the fresh strawberry juice following this simple protocol and the DNA is all yours! 🙂

World of Technology and Science

Finally, for a whole week at the end of September, DIYbio Groningen participated in the World of Technology and Science exhibition at the jaarbeurs in Utrecht. This exhibition was an opportunity for many companies involved in laboratory hardware, electronics and automation to showcase their products. It was great to see the latest innovation of lab hardware but also fun to explain to people that some of these machines can be built at a tenth of the price.

Together with other Dutch DIYbio groups we presented some examples of open-source laboratory hardware developed by groups from around the world:

Night of Art & Science, Groningen 2014

Collision Art & Science: DIYbio

This year University of Groningen turned 400. As a part of its anniversary celebration, the University teamed up with  ‘The Night of Art & Science’ to make this year’s event even more interesting. Aiming to merge these two fields during in one night is something beautiful and extraordinary. DIYbio Groningen could not miss this chance to share the ideas and ideals of the open scientific community and took part in the event with a stand.

None of us expected what would happen:

For over five hours, a huge flow of participants was flooding our room. Many were interested to discover our PCR machine, Victor’s 3D printer, our Arduino boards and learning about DIYbio Groningen’s mission and work. I,as the appointed photographer, saw and captured lot’s of laugh, curiosity, and most importantly – an interest in public. Some people were asking about our current projects, some wondered about the future of the DIY community and some were also sharing their skeptical views.

Overall, we all were happy to share our passion with people from a large variety of fields and backgrounds and ages. Thanks to organizers of the event, we had vivid illustrations of our mission and our PCR machine, made by the talented illustrator – Wies van der Velde – who communicated our aims and work it in such a clever and funny way. Thank you! 

A big thanks to everyone who participated! For us it was a fun and very entertaining experience!
