The L-Arginine/Urea/Ammonia test kit is specific and a rapid measurement and analysis of L-arginine, urea and ammonia in grape juice/must and wine.

Overview

• Rapid isolation of both small and large species of DNA from urine
• Convenient spin column format
• Effective removal of PCR inhibitors
• Purified DNA is highly suited to sensitive downstream applications
• Allows for the purification of viral DNA from urine

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 Kit

This kit provides a fast, reliable and simple procedure for isolating DNA from urine volumes ranging from 50 μL to 1.75 mL of urine. Multiple samples can be processed in 30 minutes.

Urine DNA Isolation Kit (Slurry Format)

This kit provides a fast, reliable and simple procedure for isolating DNA from urine volumes ranging from 3 mL to 25 mL. Multiple samples can be processed in 30 minutes. Multiple samples can be processed in 45 minutes.

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.

endo-BCN-PEG4-PFP ester is a click chemistry reagent containing a PFP ester and a BCN group. PFP esters have similar applications as the NHS esters, but are more stable in aqueous solution. They can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The BCN group cais reactive with azide-tagged molecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
