I have a question I could not get an understandable reply from Google and I am no expert in the matter, so my plead to you is if you could give me practical and relatively easy to follow advice.
With the view of the breakthroughs in DNA research and all the anticipated applications to medicine in the near-future, I am willing to build a storage of the DNAs in my family (eg 20-30 people, some at a very old age). The use may not be for cloning :) but rather, for eg to map and trace specific hereditary genes when such services become more available to the wide public; and thus, probably help with a personalized medicine for someone, or find genome problems, and probably be able to 'turn them off' at some point.
Is there a way I can extract cells (ie from inside the cheek, or hairs), and store them for a few decades while preserving the DNA (eg put them in a freezer at -18C or in some solution)? I have only common knowledge in this area so apologies if the examples are silly, but I assume you can understand my point.
I would be grateful if you provide practical instructions as: "you buy 500ml of the chemical xx"; or "mix 150ml of xx and 200ml of zz", so me and anyone who finds the idea appealing, can follow. Ps-the lower the costs of the procedures, the better (I found some personal "dna vaults" costing several '000$).
Thank you for your consideration!
