Rapid and convenient method to detect microorganisms in up to 10 g of soil samples Process all soil types Efficiently remove organic substances using the OSR Solution Remove all humic acid from DNA samples using the Maxi Humic Acid Removal Columns Fast and easy processing using a rapid spin-column format Isolate high quality total DNA from a variety of microorganisms including bacteria, fungi and algae Norgen’s Soil DNA Isolation Maxi Kit provides a convenient and rapid method for the detection of microorganisms from large soil samples (up to 10 grams) . All types of soil samples can be processed with this kit, including common soil samples and difficult soil samples with high humic acid content such as compost and manure. The kit removes all traces of humic acid using the provided Humic Acid Removal Column and the OSR (Organic Substance Removal) Solution. A simple and rapid spin column procedure is then used to further purify the DNA. Total genomic DNA can be isolated and purified from all the various microorganisms found in soil, such as bacteria, fungi and algae. The purified DNA is of the highest quality and is fully compatible with downstream PCR and NGS applications, as all humic acid substances and PCR inhibitors are removed during the isolation.
