Processes for the preparation and separation of macromolecules |
摘要 |
A process for the electrophoretic separation of charged macromolecules includes applying to the macromolecules a periodic sequence of pulses. Each period comprises a multiplicity of electric field pulses of negative and positive polarities. The negative polarity pulses are applied for a longer total time duration than the positive polarity pulses within each period. The average intensity of the negative polarity pulses is less than the average intensity of the positive polarity pulses.
