Safety Information Caution Notice The QuikPrep ElectroPrep System is intended for laboratory use only and may be used in research and development applications. These systems have been designed to meet the applicable safety requirements for electrical equipment for measurement, control, and laboratory use.
Product Overview The QuikPrep® ElectroPrep™ Electrodialysis System is an extremely versatile patented sample preparation technology that is capable of separating samples by both size and charge. It is ideal for the rapid purification of proteins, nucleic acids, carbohydrates and other biomolecules. Membranes of different MWCO (molecular weight cut off), from 100 to 300,000 daltons, can be used for selective buffer exchange, dialysis, filtration, concentration, fractionation and elution.
Using the ElectroPrep Unit Assembly and Use A functional ElectroPrep System consists of the ElectroPrep Tank, power supply, and one or more Dialyzer Units. The ElectroPrep Tank (74-1196) is supplied with a tank, lid and connectors, and a replacement gasket. Power supply and Dialyzer Units must be purchased separately. The ElectroPrep System uses at least one Dialyzer Unit to perform a sample electrodialysis.

Using the ElectroPrep Unit Dialyzer Units can be configured in a number of more complex ways to perform different applications using a combination of components: • Dialysis Chamber: the major receptacles for either samples or dialyzed materials. Includes one main chamber with two open ports and two open end caps. The sample chambers are made of PTFE, an inert material especially suited for high sample recovery and are available in a range of 50 µl to 1500 µl volumes.

Using the ElectroPrep Unit • Dialysis Membranes are added at one or both ends or between Dialysis Chamber and/or Link Chambers and Unions. Membranes with molecular weight cut off points (MWCOs), ranging from 500 to 300,000 daltons, may be used in combination with different Dialysis and Link Chambers for selective elution, filtration, dialysis, fractionation and concentration of complex samples.
Using the ElectroPrep Unit Open End Caps: Secondary Link Chamber: Primary Link Chamber: Lock membranes Can be connected to a Can be connected to a into position. Primary Link Chamber, and Dialysis Chamber, and joined with an Open End Cap joined with a Secondary Link at the other end.

Using the ElectroPrep Unit 3. Choose Dialysis Membranes of suitable size, type and MWCO depending on the application being done and the molecular weight of the biological molecule of interest. a. Membrane Type: Take into account the membrane’s suitability for use in aqueous or organic solvents.
ElectroPrep Protocols Electrodialysis through Simultaneous Exchange of Buffers (Configuration #1) Applications • Rapidly remove 100% of primer after PCR reaction (5 to 10 minutes). • De-salting of neutral materials that do not move in an electric field (such as sugars) or charged molecules at their isoelectric point.
ElectroPrep Protocols Selective Electrofiltration/Concentration/Separation Based on Different Charges of Biomolecules (Variation of Configuration #2) Applications • Separation and purification of biomolecules with unknown isoelectric potential In Configuration #2 the sample is placed in a union between two membranes (b), both of which should have a MWCO larger than the desired biomolecules.
ElectroPrep Protocols Rapid and Selective Electrofiltration or Concentration (Variation of Configuration #2) Applications • Concentration of small samples and/or selective filtration In this Configuration #2 variant, the sample is placed in the sample compartment comprised of a Dialysis Chamber (1) and the Union connected to a receiving Dialysis Chamber (2) of same or smaller volume. The MWCO of membrane (b) should be larger than the molecular weight of the biomolecules and the MWCO of membranes (a) and (c) should be smaller.
ElectroPrep Protocols Electroelution and Electrofractionation of DNA, Proteins or Other Biomolecules from Gel Pieces (Variation of Configuration #2) Applications • Elution of DNA, proteins, or other biomolecules from one or more gel pieces. Optionally, electrofraction of eluted biomolecules by size may be done at the same time. Using the ElectroPrep system in this Configuration #2 variant, elution of DNA, proteins, or any other biomolecules from a gel slice/plug can be achieved quickly and easily with excellent recovery.
