The PureLink HQ Mini Plasmid Purification Kit is designedfor the isolation of high-quality plasmid DNA that is suitablefor restriction enzyme digestion, PCR, sequencing, bacterialcell transformation, and mammalian cell transfection.Using the kit, plasmid DNA can be isolated from varyingamounts of bacterial cells.

The PureLink HQ Mini Plasmid Purification Kit has thefollowing advantages:
• Higher spin column capacity for plasmid DNA ascompared to other commercially available plasmidpurification systems
• Designed to isolate high-quality plasmid DNA in less thanan hour
• Minimal genomic DNA contamination of the purifiedsample
• Reliable performance of the purified DNA in downstreamapplications

Process overview
Bacterial cells are pelleted, resuspended, and lysed. Thelysate is then neutralized and conditions are adjusted forsubsequent binding. After clarification by centrifugation, thelysate is processed through the PureLink spin column. TheDNA binds to the silica-based membrane in the column, andimpurities are removed by a single wash step. The DNA isthen eluted in Elution Buffer or water.

For Research Use Only. Not for use in diagnostic procedures.

Contents & Storage
The PureLink HQ Mini Plasmid DNA Purification Kit includes sufficient PureLink columns, collection tubes, elution tubes, and reagents for 100 purifications. Store components at room temperature. Store Resuspension Buffer after addition of RNase A at +4°C. All reagents are guaranteed stable for 6 months when properly stored.

Frequently asked questions (FAQs)

I'm getting low/no plasmid DNA after purification using a PureLink HiPure kit, even though there was measurable absorbance. Do you have any suggestions for what I can do?

A common problem encountered with absorbance measurements is turbidity of samples. (This could be caused by residual resin from the column.) If there is insoluble material in the cuvette (not often detected by the naked eye), much of the UV light is not absorbed but scattered, leading to an artificially high UV absorbance reading (at 260 or 280 nm, for example.) If your A260 is high, we recommend that you check the A320 to determine if there is resin in the sample. You can also try to centrifuge or filter (0.2 µm filter) your sample to remove any resin and then recheck the concentration.

I've run out of buffer when using the PureLink HiPure Plasmid Purification Kit (Cat. No. K210018). Can I purchase the buffers separately?

Yes, we would recommend purchasing the PureLink HiPure BAC Buffer Kit (Cat. No. K210018). This kit includes Resuspension Buffer (R3) (250 ml), Lysis Buffer (L7) (250 ml), Precipitation Buffer (N3) (250 ml), and RNase A (20 µg/ml) (5 ml).
You will need to add less RNase A than stated on the bottle label of the R3 buffer in this kit. It says to add 5.6 mL of RNase A. This is the correct amount for the BAC protocol; however, if you are performing standard plasmid isolation, 1.4 mL RNase A should be added.

Plasmid DNA isolated using a PureLink column-based purification kit from an endA+ strain is degraded after a restriction digest. Do you have a suggestion for this?

The HiPure kits should remove all protein from the DNA including endonucleases. For the silica-based PureLink Quick Plasmid Miniprep Kit, we recommend an extra wash with the optional Wash Buffer W10 to remove endonucleases. This solution is not compatible with the HiPure system and should not be used with those kits. Alternatively, heat the eluted DNA in TE for 10 min at 70 degrees C. This should heat-inactivate any contaminating nucleases.

I'm seeing extra bands present after plasmid purification using your PureLink column-based system. What could cause this to happen?

Extra bands can occur when plasmid DNA is nicked and/or permanently denatured. Plasmid DNA that has been nicked (covalently opened) will run slower than supercoiled DNA during electrophoresis. A small amount of this species of DNA is common and is suitable for downstream applications. Permanently denatured DNA will migrate ahead of the supercoiled DNA and may not be suitable for downstream applications. Do not allow the lysis reaction to proceed longer than 5 minutes.

My purified DNA has particles in it after column-based plasmid purification. Any suggestions?

We have seen this on occasion. The particles do not affect quality of the DNA. Remove the particles by performimg a 1 minute centrifugation at 12,000 x g.
