NOWEDGESequencingGels
I have been using an alternative to wedge gels that saves acrylamide, cuts gel drying time to 20 min and gives as good or better band squashing at the bottom of the gel. It was published in BioTechniques about 3 or 4 years ago (email me if you want the reference).The method goes as such:Run the gel with 0.5X TBE in the top tank and normal 1 X TBE in the bottom tank. Just after the last (or in the case of one load - t......阅读全文
