A high-throughput protocol for extracting high-purity genomic DNA from plants and animals.

چکیده
DNA extraction techniques that employ the reversible binding of DNA to silica via chaotropic salts can deliver high-quality genomic DNA from plant and animal tissues, while avoiding the use of toxic organic solvents. Existing techniques that use this method are either prohibitively expensive, or are applicable to only a restricted set of taxa. Here we describe a cost-effective DNA extraction technique suitable for a wide range of plant and animal taxa that yields microgram quantities of high-molecular-weight genomic DNA at a throughput of 192 samples per day. Our technique is particularly robust for tissue samples that are insoluble or are rapidly discoloured or oxidized in standard DNA extraction buffers. We demonstrate the quality of DNA extracted using this method by applying the amplified fragment length polymorphism technique to plant species.

An efficient and simple CTAB based method for total genomic DNA isolation from low amounts of aquatic plants leaves with a high level of secondary metabolites
An efficient DNA isolation protocol specifically modified to get pure quality DNA required for molecular studieshas been reported in this paper. Some aquatic plants (Potamogeton spp., Ceratophyllum demersum and Myriophyllum spicatum) were used for the study. The protocol developed will be useful in getting high and pure DNA. Instead of using the available DNA extraction kits, this protocol can ...

The principle of this method was to screen the pharmacological activity of six prepared polyphyto formulations by using high throughput screening method for their nootropic action. The study was performed in three stages using one, two and three animals, respectively in a group. Test formulations were given p.o daily at the dose of 50 and 100 mg/kg body weight. The test formulations were compar...
متن کاملIsolation of high-quality RNA from a wide range of woody plants
Isolation of high-quality RNA is one of the most crucial methods in molecular biology. RNA extraction from woody plants has been problematic due to the presence of rigid and woody tissues, large amounts of polysaccharides, polyphenols and other secondary metabolites. Here we present a suitable protocol for RNA isolation from a wide range of woody plants that includes eight gymnosperms and four ...
