PureYield™ Plasmid Midiprep System

he PureYield™ Plasmid Midiprep System is designed to isolate transfection-quality plasmid DNA. The system provides a rapid method for purification of 100–200μg of plasmid DNA from 50ml bacteria culture. Plasmid DNA can be purified in as little as 30 minutes with the vacuum protocol, greatly reducing the time spent on purification compared to silica resin or other membrane-column methods. An alternative protocol allows purification of over 400μg of high-copy-number plasmid from 250ml of E. coli culture.

Description

The PureYield™ Plasmid Midiprep System is designed to isolate transfection-quality plasmid DNA. The system provides a rapid method for purification of 100–200μg of plasmid DNA from 50ml bacteria culture. Plasmid DNA can be purified in as little as 30 minutes with the vacuum protocol, greatly reducing the time spent on purification compared to silica resin or other membrane-column methods. An alternative protocol allows purification of over 400μg of high-copy-number plasmid from 250ml of E. coli culture.

The PureYield™ Plasmid Midiprep System incorporates a unique Endotoxin Removal Wash designed to remove substantial amounts of protein, RNA and endotoxin contaminants from purified plasmid DNA. Removal of contaminants improves the robustness of sensitive applications such as eukaryotic transfection, in vitro transcription and coupled in vitro transcription/translation (e.g., TnT® Quick Coupled Transcription/Translation System). Purification is achieved without isopropanol precipitation of purified plasmid DNA or extensive centrifugation, providing rapid purification from a single method.

The system has been designed for use with centrifugation or vacuum (e.g., the Vac-Man® Laboratory Vacuum Manifold).

The Eluator™ Vacuum Elution Device is used to elute nucleic acids from PureYield™ Midiprep or Maxiprep columns. It consists of two pieces, a blue base and a clear column assembly. The base interfaces with a Vacuum Manifold that contains Luer-Lok® fittings, such as the Vac-Man® Laboratory Vacuum Manifold (Cat.# A7231), and holds a 1.5ml tube to capture the eluted nucleic acids. The column assembly accepts PureYield™ Midiprep or Maxiprep columns.

The Eluator™ Device eliminates the requirement for a centrifuge with a swinging bucket rotor for nucleic acid purification, simplifying and speeding purification protocols.

Features – Benefits

  • Improved Productivity : Vacuum protocol allows plasmid DNA purification in as little as 30 minutes.
  • Confidence in Results : High purity and concentration of plasmid DNA gives proven performance in transfection, in vitro expression and other molecular biology applications.
  • Ease of Use : Simple protocol eliminates tedious high-speed centrifugation, gravity-drip columns, and post-elution alcohol precipitation.
  • Flexibility : PureYield™ membrane column allows purification of large amounts of plasmid DNA, exceeding the capabilities of other midiprep systems.
