| titleOfInvention | Method and apparatus for continuous flow isoelectric focusing for purifying biological substances |
| abstract | The invention provides a continuous flow apparatus and method for purifying charged substances from solutions or suspensions by isoelectric focusing on an industrial scale. The apparatus comprises a separating chamber, a pair of vertical electrodes (9) located at the extremes of the apparatus, an anion- or a cation-selective membrane (10) located near each of the electrodes (9) for separating electrode spaces from a central part of the apparatus, one or more outflow ports (12) for separating liquid fractions at the upper part of the chamber, two secondary outflow ports (11) being provided in the upper part of each of the electrode spaces, one or more vertical wall(s) (6) between each of said outflow ports partitioning the chamber at least at the height of said outflow ports (11, 12), and a plurality of vertical permeable partition walls (13) to enable a convection-free upward flow. The apparatus invention does not require additional amphoteric buffering solutions to establish a suitable pH gradient, and can be used for purification of polynucleotides, amino acids, peptides, proteins, organic solvents and beverages. |
