pathogen DNA isolation (Gram positive and Gram negative)
Total genomic DNA was isolated from 200 mg of processed (chicken soup, beef jerky) or non-processed (raw pork, olive dressing, ground beef) food materials using Norgen's Food DNA Isolation kit. Following isolation, 10ul from each 100ul elution was loaded on 1% TAE agarose gel. Lane M: Norgen's HighRanger 1kb DNA Ladder.
DNA was isolated from 200 mg of processed (chicken soup, beef jerky) or non-processed (raw pork, olive dressing, ground beef) food materials usingNorgen's food DNA Isolation Kit. DNA purity was thendetermined using aNanoDrop. All the DNA isolated from the different food samplesshowed a high quality (260/280=1.9-2.1).
Total DNA was isolated from 200 mg samples of different food materials (processed and non-processed) using Norgen's Food DNA Isolation Kit. Next, 4ul of the elution was then used as the template in 20ul PCR reactions using universal 5s rDNA primers (A) and prokaryotic 16s rDNA primers (B) in real-time PCR (SYBR Green). Norgen's DNA was successfully amplified, indicating the high quality of the inhibitor-free DNA for GMO and pathogen detection from diversified food materials.
This kit provides a rapid spin column method for the isolation and purification of total DNA from a wide range of food samples originating from animals or plants. The kit is designed for identification of GMO-DNA or animal components in food and feed and can be used for a wide range of starting materials including raw or processed food, meat, liquids, sauces and dairy products including milk, cheese and yogurt. This kit also provides a convenient method for the detection of food-related pathogens and will isolate such DNA (enriched or as is) including Gram-positive bacteria, Gram-negative bacteria, yeast and fungi which may contaminate food sources. A number of pathogens have been tested including E. coli O157:H7, Staphylococcus, Listeria monocytogenes, Salmonella enterica & Campylobacter jejuni. The purified DNA is of the highest integrity, and can be used in a number of downstream applications including PCR based detection, sequencing and genotyping.
