This week has been very long, included 5 train journeys to London and one trip in the back of a van. One very long crystal freezing session. I always find it so sad freezing my little protein crystals. They look so beautiful. But I suppose what I need of them is data. Here is a photo of some of my crystals. The different colours are due to birefringence (double refraction) when looking down an optical microscope with a pair of crossed polarised filters.
Very tired now. Have a great weekend.
