Isolate total DNA and RNA from all microorganisms found in water, including bacteria, fungi and algae RNA and DNA are both column purified simultaneously using the same column Elution contains concentrated DNA and RNA without the need for further precipitation Complete RNA (including microRNA) without phenol Isolated RNA and DNA are of high quality and integrity for all downstream applications Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix These kits provide a convenient and rapid method for the isolation of microorganisms from water samples. The kits allow for the rapid isolation and purification of total RNA and DNA simultaneously from the microorganisms found in different types of water samples. The total RNA and DNA (including genomic DNA) are isolated from all the microorganisms found in the water, including bacteria, fungi and algae without the use of any inhibitory organic substances The kit purifies genomic DNA, and all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA) . The purified RNA and DNA are highly concentrated, and can be used directly in a number of downstream applications including PCR, qPCR, RT-PCR, qRT-PCR, Northern blotting, Southern blotting and sequencing reactions. Water RNA/DNA Purification Kit (Spin Column + Filters Kits) These kits are available with 0.45 μm or 0.22 μm filter formats for capturing microorganisms present in the water. Water RNA/DNA Purification Kit (Spin Column) This kit is sold without filters columns.
