E.Z.N.A.^® Plant DNA Mini Kits allow rapid and reliable isolation of high-quality total cellular DNA from a wide variety of plant species and tissues. Up to 100 mg of wet tissue (or 30 mg dry tissue) can be processed in less than 1 hour.

Principle

The Plant DNA mini kit combines the reversible nucleic acid-binding properties of HiBind^® matrix with the speed and versatility of spin column technology to eliminate polysaccharides, phenolic compounds, and enzyme inhibitors from plant tissue lysates. Purified DNA is suitable for PCR, restriction digestion, and hybridization techniques. The use of mini-columns facilitate the binding, washing, and elution steps thus enabling multiple samples to be simultaneously processed.

Procedure

Dry or fresh tissue is disrupted and then lysed in specially formulated buffers containing a detergent. Proteins, polysaccharides, and cellular debris are subsequently precipitated. Contaminants are further removed by isopropanol precipitation of DNA. Binding conditions are then adjusted and the sample is applied to a HiBind^® DNA spin-column. Two rapid wash steps remove trace contaminants such as residual polysaccharides and pure DNA is eluted in water or low ionic strength buffer. Purified DNA can be directly used in downstream applications without the need for further purification.

Applications

RNA purified using the Plant RNA kit is suitable for the following applications :

• PCR
• Restriction Digestion
• Hybridization Techniques
