| abstract |
The invention relates to a medium for analytic and preparative electrophoresis comprising a content of acids and bases of different pK S values. Said medium contains at least two acids, whose pK S values (ΔpK S ) of adjacent acids are no greater than 1.0 but preferably range from 0.8 to 0.5, and contains at least two bases, whose pK S values range from approximately 1.5 to 11, whereby the difference of the pK S values (ΔpK S ) of adjacent bases is no greater than 1.0 but preferably ranges from 0.8 to 0.5. |
