The quality of the Presto™ DNA/RNA/Protein 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 and total protein 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. The purified protein is quantified by bradford assay and analyzed on SDS-PAGE.
Figure 1. Genomic DNA and Total RNA from 1.5 x 106 HeLa cells was extracted using the Presto™ DNA/RNA/Protein Extraction Kit. 10 µl aliquots from 200 µl eluates of purified genomic DNA and 10 µl aliquots from 50 µl eluates of purified total RNA was analyzed by electrophoresis on a 1% agarose gel.

Figure 2. DNA and RNA from 3 human blood samples (500 µl) was extracted using the Presto™ DNA/RNA/Protein Extraction Kit. 10 µl aliquots from a 100 µl eluate of purified genomic DNA and a 50 µl eluate of purified total RNA were analyzed by electrophoresis on a 1% agarose gel.

Figure 3. Protein was extracted from 1.5 x 106 HeLa cells in 200 µl of DV buffer using the Presto™ DNA/RNA/Protein Extraction Kit. 20 µl aliquots from a 200 µl eluate of purified protein were analyzed on a NuPAGE4-12% Bis-Tris gel and stained with coomassie blue (120 µg of total protein with a concentration of 0.6 µg/µl).
