Overview
The E.Z.N.A.® Plasmid Mini Kit I is designed to isolate up to 25 µg of high-quality plasmid DNA from 1-5 mL bacterial cultures in less than 30 minutes. Plasmid DNA purification follows the alkaline-lysis method and is simplified with HiBind® Mini Column technology into three quick steps: Bind, Wash, and Elute. Purified plasmid DNA is immediately ready for a wide variety of downstream applications such as routine screening, restriction enzyme digestion, transformation, PCR and DNA sequencing.The E.Z.N.A.® Plasmid Mini Kit is available in two formats – Q-spin (D6942) and V-spin (D6943). D6942 (Q-spin) features columns that are capless whereas D6943 (V-spin) includes columns that have a cap attached. The columns are otherwise identical in use and application and can be used in both vacuum or centrifugation protocols.
- Rapid – Purification of plasmid DNA in less than 30 minutes
- Safe – No Phenol/chloroform extractions
- Versatile – Spin and vacuum formats available
- High-quality – DNA is suitable for a variety of downstream applications

DNA Concentration Comparison
Figure 1. pGEM plasmid was purified from 4 mL DH5α cultures harboring the plasmid and eluted in 50 µL volume using kits from Omega Bio-tek and Company Q according to manufacturer’s recommended protocols. Plasmid DNA concentration was determined by optical density measurements using Thermo Scientific’s NanoDrop™ 2000c system.
Super-Coiled DNA
Figure 2. 5 µL of purified pGEM plasmid was analyzed on a 1% Agarose gel. Plasmid was isolated from 1 mL DH5α cultures harboring the plasmid using Omega Bio-tek’s E.Z.N.A.® Plasmid Mini Kit I.
