The Norgen water purification system has been designed in conjunction with experts from Millipore Sigma. The Ultrapure NFW is purified in a two-stage process. The first stage, to produce type II water, includes pre-treatment with activated charcoal and polyphosphate, this water then undergoes reverse osmosis, electro-deionization and ion exchange to remove contaminants as well as UV treatment for disinfection. The Pure water then flows to a second system in a clean room with an additional 4 layers of purification. After passing through an additional ion exchange column, the water is then subjected to Ultrafiltration to remove particulates, bacteria, & ionic contaminants down to trace level, the water is then treated with UV light (182 nm wavelength) to break down organic matter. Lastly a second Ultrafilter for the production of pyrogen-, nuclease- and bacteria-free water at 18.2 MΩ. This water is of utmost purity and suitable for direct use in molecular biology applications such as qPCR and NGS, as well as cell culture and other applications.

General information
Champion™ Competent Cells are chemically competent cells, which were prepared by SMOBIO to make E. coli perform excellent transformation efficiency. Standard transformation protocol is recommended for large plasmids or non-ampicillin selection. Time-saving transformation protocol is recommended for simple and rapid transformation. Champion™ Competent Cells are one of the fastest and simplest ready-to-use competent cell products in the world.
Kit contents
Shipping condition
Throughout the shipping process, the temperature is maintained under -70°C.
Storage and expiration
Champion™ Competent Cells must be stored between -70°C to -80°C. Subsequent freeze-thaw cycles will reduce transformation efficiency. If high efficiency is required for the experiment, do not use aliquots that have gone through several freeze-thaw cycles. The efficiency of Champion™ Competent Cells lasts for 1 year with proper storage.

These kits provide a rapid method for the isolation and purification of total RNA and DNA sequentially from a single sample of cultured animal cells and tissues, blood, bacteria, yeast, or fungi. The lysate is passed over two columns: 1) a DNA column and 2) an RNA column. Total RNA of all sizes is purified, including microRNA. Both DNA and RNA are of the highest purity and yield.
These kits are ideal for researchers who are interested in studying the genome and transcriptome of a single sample, such as for studies of microRNA profiling, gene expression including gene silencing experiments or mRNA knockdowns, studies involving biomarker discovery, and for characterization of cultured cell lines. Norgen’s RNA/DNA Purification Kits are especially useful for researchers who are isolating macromolecules from precious, difficult to obtain or small samples such as biopsy materials or single foci from cell cultures, as they eliminate the need to fractionate the sample. Furthermore, analysis will be more reliable since the RNA and DNA are derived from the same sample, thereby eliminating inconsistent results. The purified macromolecules are of the highest purity and can be used in a number of different downstream applications
