DNA/RNA Extraction Kit (DR050/DR100)

DNA RNA Extraction Kit
DNA/RNA Extraction Kit (DR050/DR100)
The Presto™ DNA RNA Extraction Kit provides an efficient method for purifying genomic DNA and total RNA simultaneously from cultured cells, animal tissue, whole blood and biological fluids such as serum and plasma. Chaotropic salt is used to lyse cells and degrade protein, allowing DNA to bind to the genomic DNA mini spin column. The flow-through containing RNA can then be transferred to the RNA mini spin column for RNA binding. Contaminants are removed using a wash buffer and the purified genomic DNA is eluted in a low salt Elution Buffer and the purified total RNA is eluted in RNase-free Water. The entire procedure can be completed in 25 minutes without phenol/chloroform extraction or alcohol precipitation. The purified DNA, approximately 20-30 kb, is suitable for use in PCR or other enzymatic reactions and the purified RNA (including miRNA) is ready for use in RT-PCR, Real-time PCR, northern blotting, primer extension, mRNA selection and cDNA synthesis.

Quality Control

The quality of the Presto™ DNA/RNA Extraction Kit is tested on a lot-to-lot basis according to Geneaid's ISO-certified quality management system by isolating genomic DNA, total RNA from 1.5 x 106 cultured animal cells. The purified DNA and total RNA is quantified with a spectrophotometer and analyzed by electrophoresis on a 1% agarose gel.
