DBCO-S-S-acid is a cleavable reagent for introduction of a carboxylic acid moiety to azide-containing biomolecules using copper-free Click Chemistry. PEG spacer arm provides better solubility to the labeled molecules in aqueous media. The disulfide bond in this linker can be cleaved using reducing agents such as DTT, BME and TCEP.

Both high molecular weight DNA (greater than 1 kb in size; mostly cell associated) and the smaller DNA (150 – 250 bp; derived from the circulation) is effectively isolated and purified using a rapid and convenient spin column protocol. This kit can be used to isolate DNA from a broad range of viruses in urine as well. Salts, metabolic wastes, proteins and other contaminants are removed to yield inhibitor-free DNA for use in sensitive applications. The DNA is of excellent quality for various downstream applications such as PCR, qPCR and DNA fingerprinting, methylation studies and more.
This kit is fully compatible with Norgen’s Urine Collection and Preservation Tubes.

Urine DNA Isolation Maxi Kit (Slurry Format)
This kit provides a fast, reliable and simple procedure for isolating DNA from urine volumes ranging from 25 mL of urine up to 80 mL. Multiple samples can be processed in 45 minutes.
Background
DNA found in urine can be divided into 2 basic categories. The larger species, genomic-DNA (gDNA), is generally greater than 1 kb in size, and appears to be derived mainly from exfoliated cells. The second species is smaller, generally between 150 and 250 bp (apoptotic-DNA), and derives, at least in part, from the circulation. The second species is also considered as an RNA/DNA hybrid as reported by Halicka et al. (2000). Both types of DNA can be isolated reliably using this kit.

Storage Conditions and Product Stability
All buffers should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm up Slurry B1 and Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed. Slurry B1 contains a grey resin that will not dissolve when warmed.

Overview
This kit provides a fast and simple procedure for the isolation of total proteins from tissue, bacteria, yeast or mammalian cells without the use of SDS, Triton® X-100 and other detergents. Detergents are extensively used to prepare protein samples; however, these detergents have undesirable effects on downstream analysis. These effects include extraneous peaks in mass spectrometry, artifacts with chromatography and electrophoresis, interference with microinjection into cells and interference with protein immunization.
The Detergent-Free Total Protein Isolation Kit maintains high protein recovery and yields proteins that are 100% detergent-free. Purification is based on using Norgen’s proprietary resin together with Lysis Solution, followed by protein filtration using a filter column (provided). The purified proteins can be used in a number of downstream applications including mass spectrometry, SDS-PAGE, isoelectric focusing, NMR spectroscopy and more.
Each Lysis Tube is able to process up to 50 mg of tissue, 1010 bacterial cells, 109 yeast cells or 107 mammalian cells. Preparation time for 12 samples is less than 10 minutes.
