Principle

A bacterial culture is harvested and lysed. The lysate is then cleared by centrifugation and applied on the silica column to selectively bind DNA molecules at a high salt concentration. The adsorbed DNA is washed to remove contaminants, and the pure plasmid DNA is eluted in a small volume of elution buffer or water. The purified DNA is ready for immediate use in all molecular biology procedures, such as fast and conventional digestion with restriction enzymes, PCR, in vitro transcription, transformation, and automated sequencing.

PureLink™ Pro Quick96 Plasmid Purification Kit (Invitrogen™)

The PureLink® Pro Quick96 Plasmid Kit combines advanced silica plate extraction chemistry with an optimized 96-well plate design for manual or automated processing of plasmid DNA from E. coli in as little as 45 minutes (Table 1). Using the PureLink® Pro Quick96 Plasmid Kit, you will:

• Obtain consistently high yields of high-purity plasmid DNA
• Experience ease of use and better performance due to improved plate design and protocol
• Increase processing flexibility with protocols for centrifuge, vacuum manifold, or automated platforms

How it works
The PureLink® Pro Quick96 Plasmid Kit uses two 96-well plates, a filtration plate (clear O-ring), and a binding plate (red O-ring) to purify plasmid DNA. Bacterial cells are subjected to alkaline lysis and are pelleted by centrifugation. The bacterial lysate is then applied to the Quick96 Filtration Plate for clearing and collection in the Quick96 Binding Plate, where the plasmid DNA binds to the silica membrane. After washing steps to remove contaminants, purified DNA is eluted and ready for use in downstream applications. The entire procedure can be completed in 45 minutes (Figure 1).

Improved plate design
The PureLink® Pro Quick96 Plasmid Kit provides optimized semiskirted 96-well plates for improved performance and results (Figure 2). The Quick96 Filtration Plate is designed for fast and efficient clearing of the bacterial lysates. The Quick96 Binding Plate offers an increased binding capacity of up to 20 µg plasmid DNA. In addition, the plate nozzles with annular collar prevent cross-contamination of samples and improve drying of the silica membrane to prevent ethanol carryover. In addition, sample processing can be performed manually using a benchtop vacuum manifold, by centrifugation, or with an automated liquid handling platform. The semiskirted plate design is compatible with most vacuum manifolds on robotic workstations.

Higher yields and purity
The PureLink® Pro Quick96 Plasmid Kit allows rapid and reproducible purification of up to 20 µg of plasmid DNA from E. coli strains grown in up to 5 ml LB, 3 ml 2xYT, or 3 ml TB. In an automated platform using 1.5 ml E. coli culture grown overnight in a square-well block, typical yields are 5-15 µg plasmid DNA, with an average of 9.4 µg (Figure 3). The resulting plasmid DNA is supercoiled with no detectable genomic DNA or RNA (Figure 4). The PureLink® Pro Quick96 Plasmid Kit provides higher yields of high-quality plasmid DNA for use in common downstream applications such as automated sequencing, PCR, restriction enzyme digestion, and cloning.

PureLink™ HiPure Plasmid FP (Filter and Precipitator) Maxiprep Kit (Invitrogen™)

The PureLink™ HiPure Plasmid FP (Filter and Precipitator) Maxiprep Kit isolates plasmid DNA, from cell pellet to ultrapure DNA, in less than one hour. Using the HiPure Filter Columns and HiPure Precipitators supplied in the kit, you can purify plasmid DNA without the centrifugation steps required in traditional isolation protocols. The quality of the purified plasmid DNA is equivalent to that obtained by two passes through cesium chloride gradients - the most rigorous method for DNA purification - making it suitable for transfection and other applications requiring high-purity plasmid DNA. The PureLink™ HiPure Plasmid FP Maxiprep Kit (Table 1) provides:
• Simple protocols - bacterial lysate clarification and isopropanol precipitation without centrifugation
• Fast results - from E. coli cell pellet to high-purity, transfection-grade plasmid DNA in about 60 minutes
• High yields - up to 850 µg from a high-copy plasmid

How it works
The PureLink™ HiPure Plasmid FP Maxiprep Kit employs an alkaline lysis method to prepare and rapidly clear bacterial lysates without the need for centrifugation (Figure 1). The unique HiPure Filter Column includes a lysate filtration cartridge integrated into the anion-exchange column for single-step lysate clarification and plasmid DNA binding. Impurities such as RNA, proteins, and other contaminants are removed with a single wash, and ultrapure plasmid DNA is eluted with a high-salt buffer. To precipitate and desalt the DNA, isopropanol is added to the eluted DNA and the mixture is then applied to the HiPure Precipitator using a large syringe. After a subsequent washing and drying step, the plasmid DNA is easily eluted from the HiPure Precipitator with either TE buffer or water. The use of the precipitator eliminates the need for centrifugation, reducing the risk of losing the DNA pellet during supernatant removal, and saving time. The resulting DNA is ready to use in the most challenging applications. The entire protocol - from E. coli cell pellet to ultrapure transfection-grade plasmid DNA - can be completed in about an hour.

Highest yields and ready-to-use concentrations
The HiPure Precipitator has been optimized to allow for lower elution volumes (down to 500 µl) to produce highly concentrated DNA without a significant decrease in yields. In fact, yields at higher concentrations are consistently higher than the competitor kits (Figure 2). Yields and concentration can be adjusted to meet the needs of your downstream application.
