E.Z.N.A.® Plasmid DNA Mini Kit I, (V-spin)


  • 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

The E.Z.N.A.® Plasmid DNA 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 DNA 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.

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

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 DNA Mini Kit I.

Yield and Quality

Table 1.  pGEM plasmid was purified from 1 mL DH5α cultures harboring the plasmid and eluted in 50 µL volume. Plasmid DNA concentration was determined by optical density measurements using Thermo Scientific’s NanoDrop™ 2000c system.

Endotoxin Level

Table 2.  Plasmid DNA purified with E.Z.N.A. Plasmid DNA Mini Kit I was used in a 5 µL Sanger sequencing reaction.  DNA was analyzed on an Applied Biosystems 3730XL.
