N-(Boc-PEG3)-N-bis-(PEG3-Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane) is a crosslinker consisting of six propargyl groups and a t-Boc protected aminooxy group. The propargyl groups can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The protected amine can be deprotected under acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research use only.

This kit provides a fast and simple spin column procedure for isolating genomic DNA from saliva samples collected and preserved using Norgen’s Saliva DNA Collection and Preservation Devices (Cat. RU49000), as well as fresh saliva samples.
Saliva DNA purified using Norgen’s kit is of the highest quality, and is compatible with a number of downstream research applications including PCR, Southern Blot analysis, sequencing and microarray analysis.
Saliva represents an excellent non-invasive alternative to blood collection. Human genomic DNA extracted from buccal epithelial cells and white blood cells found in saliva can be used in various applications in diagnostics. Saliva DNA can be used for the detection of biomarkers to diagnose a disease, follow the diseases progress or monitor the effects of a particular treatment. Saliva DNA can also be used to diagnose particular types of infections. Isolation of DNA from saliva has become an attractive alternative to isolation from blood or tissue due to the fact that sample collection is non-invasive, the samples can be collected by individuals with little training, and no special equipment is required. Norgen’s Saliva DNA Isolation Kit provides a fast and simple procedure for isolating genomic DNA from both preserved saliva samples and fresh saliva samples.

This kit enables the rapid purification of amplified DNA products from PCR mixes. It is able to effectively remove PCR by-products including primers, dimers, enzymes, unincorporated nucleotides and mineral oil from the desired PCR product. The purified PCR products are fully compatible with restriction enzyme digestion, ligation into vectors, labeling, sequencing and more. This kit can also be used as an alternative to organic extraction and ethanol precipitation to clean up various enzymatic reactions.
The kit is also available in a 96-well format for high-throughput PCR purification. Purification with the 96-well plate can be performed using either a vacuum manifold or centrifugation.

The ProteoSpin™ Total Protein Concentration, Detergent Clean-Up and Endotoxin Removal Kits are designed for the rapid removal of endotoxins from previously purified proteins or peptides, with protein recoveries of > 95% being achieved. Endotoxins, also known as lipopolysaccharides, are cell-membrane components of Gram-negative bacteria such as E. coli. Endotoxins liberated by Gram-negative bacteria are frequent contaminations of protein solutions derived from bioprocesses. Due to the high toxicity of endotoxins in vivo and in vitro, their removal from protein preparations is often necessary prior to the use of the protein in downstream applications. These kits efficiently reduce endotoxin levels to ≤ 0.01 EU/mg of protein, using spin column chromatography based on Norgen’s proprietary resin as the separation matrix. These kits are highly efficient in removing many different salts commonly used in the laboratory including, but not limited to, MgCl2, NaCl, KCl, CaCl2, LiCl and CsCl. The purified protein samples can be used in a number of downstream applications including sequencing, cloning, and in vitro and in vivo introduction into cells and organisms for various purposes. The simultaneous removal of salts while concentrating a dilute protein solution makes the kit a convenient method for preparing proteins before running many downstream applications such as SDS-PAGE, isoelectric focusing, X-ray crystallography, NMR spectroscopy, mass spectroscopy and other applications.
Mini Kit
The ProteoSpin™ Total Protein Concentration, Detergent Clean-Up and Endotoxin Removal Mini Kit is designed for the rapid removal of endotoxins from up to 200 μg of previously purified proteins or peptides, with protein recoveries of > 95% being achieved.
Maxi Kit
The ProteoSpin™ Total Protein Concentration, Detergent Clean-Up and Endotoxin Removal Maxi Kit is designed for the rapid removal of endotoxins from up to 4 mg of previously purified proteins or peptides, with protein recoveries of > 95% being achieved.
