the cheek cell micronuclei method is pretty simple and the protocol is already in that prezi. the great challenge is getting in the quantitative aspects. if you have a few micronuclei in 1000 cells, for instance, it is entirely normal, but if you have 20-50 in 1000, there might well be something you are exposed to that you should watch out for... in London with Cindy the other week, one person got up to about 300 cells, with no micronuclei, but it was slow going. (the foldscopes are tricky for keeping track of where you are, and we only had one proper scope) Then, in some cases (for instance a woman who had already had cancer and was scared that she might have serious signs of damage) you really don't want to find any... She got to see some of her own cells looking aok, so I was happy too! It is still a great learning experience, for sure! I only heard about all this biohacking myself a few years ago, although I got very interested in the idea of dynamic genomic integrity quite a while ago now... (I guess it was 2006 when the hair dye dilemma hit me... ) . Anyway, it would be great for you to join in these efforts for real citizen science (and I am happy to advise to the best of my ability)! My dream is to have biohackers all over getting good baselines for the ordinary levels of damage then do some sort of intervention (running, eating blueberries, drinking green tea) to see if there is some significant effect. Ex situ expts are also possible on the cheek cells (gentle collection with a toothbrush provides a lot of cells to work with) - for the comet assay just putting hydrogen peroxide is a very good positive control (but that protocol is still very far from being simple, especially when you try for 'kitchen sink' ingredients).
Thank you for your enthusiastic message!
