Claim Text:
1. A method of extending a useful electrophoresis life of an electrophoresis gel during an electrophoretic separation of at least one sample comprising the step of: adding to an electrophoresis buffer containing an electrolyte solution comprising water, at least one different zwitterion chosen from 2-amino-2methyl-1,3-propanediol (AMPD), N-(1,1-Dimethyl-2-hydroxyethyl)-3-amino-2-hydroxypropanesulfonic acid (AMPSO), N-Glycylglycine (Gly-Gly), 4-(2-hydroxyethyl)piperazine-1-propanesulfonic acid (EPPS or HEPPS), 3-(cyclohexylamino)-1-propanesulfonic acid (CAPS), 3-(cyclohexylamino)-2-hydroxy-1-propanesulfonic acid (CAPSO), 2-(cyclohexylamino)ethanesulfonic acid (CHES), N,N-bis[2-hydroxyethyl]-2-aminoethanesulphonic acid (BES), (2-[2-hydroxy-1,1-bis(hydroxymethyl)ethylamino]ethanesulphonic acid) (TES), N-Tris(hydroxymethyl)methyl-3-aminopropanesulfonic acid (TAPS), 3-N-Morpholino propanesulfonic acid (MOPS), and Piperazine-N,N′-bis(2-hydroxypropanesulfonic acid) (POPSO).
