The Chargeswitch™ -Pro Filter Plasmid Midi Kit includes 25 plasmid midipreps and provides high yield and high purity plasmid with the fastest and the simplest protocol.

The ChargeSwitch™-Pro Plasmid Filter Mini, Midi, Maxi Kits generates high-quality plasmid DNA without the use of harsh or potentially interfering reagents, for better success in downstream applications. The system is based upon a novel dual⁄nested column design which facilitate the fastest and simplest protocol for high quality plasmid. The system is composed of two columns. The inner flat bottomed column, also referred to as “lysate clarification” column, contains filter materials suitable for rapid clarification of bacterial lysate. The outer luer bottomed column, also referred to as “binding” column, contains ChargeSwitch™ (CST) derivatized membrane that immediately binds plasmid DNA from the clarified lysate. This nested-column design enables simultaneous clarification and DNA binding in a single short centrifugation (or vacuum) step. The combined advantages of novel, optimized plastics and a unique chemistry are an extreme competitive advantage of speed and convenience.

To accomplish this, the ChargeSwitch™-Pro Kit provides:

• 100% ethanol-free, guanidinium-free, organics-free, aqueous protocol for a safer, more streamlined method
• Cleaner purified product for improved performance in downstream applications
• A novel Dual⁄nested column design for simultaneous lysate clearing and binding step which offers the fastest and the simplest protocol
• Endotoxin units less than 10 EU ⁄ ug DNA for
• Vacuum Elution can be done with the EveryPrep™ Universal Vacuum Manifold (SKU # K211101)

How it works
The ChargeSwitch™ technology replaces the use of ethanol, chaotropic salts, or organic solvents for nucleic acid purification with a simple ion-exchange mechanism. At low pH values (less than 6.5) the ChargeSwitch™ surface ligand is positively charged and binds plasmid DNA. Raising the pH (>8.5) neutralizes the charge and elutes the bound nucleic acid. The ChargeSwitch™ protocol retains the ease and familiarity of the common silica spin column protocol with a binding, washing, and elution step, making adapting to the ChargeSwitch™ method effortless.

Frequently asked questions (FAQs)

I used water to elute my plasmid instead of the Elution Buffer with my ChargeSwitch kit, but saw very low plasmid yield. Why is this?

We strongly recommend using the Elution Buffer provided in the kit, and do not recommend elution with water. If you need to elute in any other buffer, be sure to use a buffer of pH 8.5-9.0 for efficient DNA elution.

What is the difference between the ChargeSwitch Pro kit and the Charge-Switch Pro filter kit?

The filter kit is based upon a dual nested column design, which facilitates the fastest and simplest protocol for obtaining high quality plasmid (less than 10 EU/µg DNA). Modified wash buffer 1 removes more endotoxin.

What is the typical yield when using the ChargeSwitch Pro Filter Plasmid Mini or Midi Kits?

The typical yield is 25 µg from a 5 mL culture for the ChargeSwitch Pro mini kit, 200 µg from a 25 mL culture for the midi kit, and 800 µg from a 100 mL culture from the maxi kit. The plasmid size range for the kits is typically 3-9 kb.

How does ChargeSwitch technology work?

Based on a patented switchable chemistry, ChargeSwitch purification utilizes the charge on a solid surface for nucleic acid capture. At lower pH, the surface chemistry holds a positive charge and attracts nucleic acid. At higher pH, the surface chemistry is neutral and any bound nucleic acid is released.
