Presto™ Plasmid DNA Concentration Kit (PC0250/251, PC0500/501, PC1000/1001)

DNA Extraction/DNA Purification

The Presto™ Plasmid DNA Concentration Kit offers a simplified replacement for time-consuming plasmid DNA precipitation procedures. The Presto™ Plasmid Concentrator will quickly and efficiently concentrate plasmid DNA in anion-exchange chromatographic DNA purification eluates collected from Geneaid Plasmid Midi Columns, Macherey-Nagel NucleoBond® AX, NucleoBond® Xtra Columns, QIAGEN® tip 500 Columns etc. Plasmid eluates are precipitated with isopropanol then passed through a Presto™ Plasmid Concentrator using a syringe. Once contaminants are removed using a proprietary Desalting Buffer, the concentrator is dried and plasmid DNA is eluted with a small volume (100-400 μl) of low salt Elution Buffer. The Presto™ Plasmid Concentrator eliminates DNA pellet loss and incomplete solubilization of precipitates to ensure highly concentrated, purified plasmid DNA. In only 10 minutes, the plasmid DNA can be used directly in a variety of sensitive downstream applications, such as transfection, sequencing, ligation, PCR, in-vitro transcription, microinjection, restriction enzyme digestion and gene gun.

Table 1.DNA Recovery is highly dependant on the volume of elution buffer used. 90% recovery can be acheived when using 600 μl of elution buffer. However, DNA concentration is decreased. When using small volumes of elution buffer, recovery is decreased but concentration is increased.
