10x, pH ~8.3;(store at NT in clean bottle)
EDTA, pH 8.0
10x stock solution is stable at NT if to clean it through 0.4µm filter;
for PAAG it is used as 1x, for agarose gel - as 0.5x;
for agarose gels it is used for separation of small (< 200bp) fragments. Generally accepted, that the purification of fragments is more complex from TBE gels.
