Tris-Acetate buffer keeps a solution slightly basic (approximate pH of 8.3), which keeps DNA water soluble (the DNA is deprotonated, H+ is removed). EDTA sequesters (chelates) metal ions which are used (as a co-factor) by many enzymes (particularly divalent Mg2+ ions), some of which can degrade the DNA.
50X Stock Solution
Add water up to a 1 L total volume, mix, and give it time to dissolve.
1X Working Solution
Add 20 ml of 50X stock to 980 ml of water.
