Despite its advantages, its use in isoelectric focusing (29,30) and DNA separations methacrylate-acrylamide copolymer for electrophoresis, as an alternative to agarose and polyacrylamides. (31) was not satisfactory, due to its inherent instability in alkaline solutions (it degrades with zero-order kinet-Although these authors additionally reported its use for separating hydrophobic proteins (42), their results ics!)…”
