    2018-12-16 · electrophoresis on polyacrylamide gel using both cationic and anionic systems in which all reagents were made up in 8 M deionized urea. Two cationic systems with running gel pH levels of 2.3 and 4.3 (1, 9) and one anionic system with a running pH of 10.4 (12) were used with 0.6 cm diam columns of 7.5% polyacrylamide gel.

    In slab gel electrophoresis the conducting buffer is retained within a porous gel of agarose or polyacrylamide. Slabs are formed by pouring the gel between two glass plates separated by spacers. Typical thicknesses are 0.25–1 mm. Gel electrophoresis is an important technique in biochemistry where it is frequently used for separating DNA ...
