Introduction
Intended Use
For the isolation of Listeria spp. from food and environmental specimens.
Principle and Interpretation
Tryptone, proteose peptone, meat extract, yeast paste powder provide nitrogen sources, vitamins, amino acids, and growth factors; sodium chloride can maintain a balanced osmotic pressure; sodium dihydrogen phosphate and potassium dihydrogen phosphate as buffering agents; aesculin are fermentable sugars; lithium chloride and other antibiotics can inhibit Gram negative bacteria and most Gram positive bacteria.

Product Info
Introduction
The Kit provides fast purification of high-quality RNA from whole blood, cells and tissues using silica-membrane spin columns with a binding capacity of 100μg RNA. There is no need for phenol / chloroform extractions and time-consuming steps such as CsCl gradient ultracentrifugation or isopropanol precipitation. The purified RNA can be used for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection and in vitro translation.

Main Functions
Isolation total RNA from 1-1.5ml whole blood
Applications
qPCR / RT-PCR, liquid or solid-phasechip analysis, hybridization and SNP detection
The Kit simplifies isolation of RNA from blood with a fast spin-column procedure. Red blood cells are selectively lysed and white cells collected by centrifugation. White cells are then lysed using highly denaturing conditions which immediately inactivate RNases. After homogenization using the DNA spin column, the sample is applied to the RNA column. Total RNA binds to the membrane and contaminants are washed away, leaving pure RNA to be eluted in 30–100µl RNase-free water (provided with the kit) for direct use in any downstream application.
Advantages
High quality – high purity total RNA can be directly used in various sensitive downstream applications
Fast – isolation of several samples can be completed in 20 minutes by using column purification method
Sensitive – RNA can be purified at the level of PG

Robust lysis buffer is well-suited to even challenging samples such as pine needle, grape leaf, etc
Isolate total RNA (including microRNA) without phenol
Isolated RNA is of high quality, integrity and diversity
Also available in 96-well format for high throughput applications
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
Norgen’s Plant/Fungi Total RNA Purification Kit provides a rapid method for the isolation and purification of total RNA, including virus and viroid RNA, from a wide range of plants. Total RNA can be purified from fresh or frozen plant tissues, plant cells or filamentous fungi samples using this kit. All sizes of RNA are purified, including microRNA (miRNA) . The procedure is rapid and convenient.
The RNA is purified without the use of phenol or chloroform. The purified RNA is of the highest quality, and can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.
Norgen’s Plant/Fungi Total RNA Purification Kit is also available in a 96-well (High Throughput) format for high throughput applications. Purification with the 96-well plates can be performed using either a vacuum manifold or centrifugation.

RNA/DNA/Protein Purification Plus Kit
This kit provides a rapid method for the high throughput isolation and purification of total RNA, DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, blood, bacteria, or yeast. The kit employs two columns: 1) for gDNA purification and 2) for RNA purification utilizing Norgen’s resin columns (superior for the binding of all RNA sizes including miRNA). The proteins are also purified on the second column after RNA elution. The proteins are eluted in buffer and are ready for downstream application without any further clean up required. The proteins can be quantified directly, used in western blots, ELISA or mass spectrometry. This kit provides a rapid spin-column method for the isolation and purification of total RNA, genomic DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, blood, bacteria, yeast, fungi or plants.
RNA/DNA/Protein Purification Plus Micro Kit
This kit provides a rapid spin-column method for the isolation and purification of total RNA, DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, microdissected samples including LCM, stem cells, sorted cells, and CTC. The total RNA, genomic DNA and proteins are all column purified in less than 30 minutes. The RNA and DNA can be eluted in as little as 20 µL while the protein can be eluted in as little as 50 µL. This kit provides the same performance as if the samples were isolated from dedicated kits.
RNA/DNA/Protein Purification 96-Well Plus Kit
The kit employs two plates: 1) for DNA purification and 2) for RNA purification utilizing Norgen’s resin (superior for the binding of all RNA sizes including miRNA). Please see the protocol schematic below.
