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 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.

AOAC Method 2020.07
The Available Carbohydrates Assay Kit method is suitable for the determination of available carbohydrates (AVCHO) comprising *total digestible starch (TDS) plus maltodextrins, sucrose, D-glucose, D-fructose and lactose. New Improved method receiving ‘First Action’ status: AOAC 2020.07. This method is designed to simulate in vivo conditions in the human small intestine (i.e. a 4 h incubation time with PAA + AMG) in parallel with recent advances in Dietary Fiber (DF) methodology (K-RINTDF: AOAC Method 2017.16) and in accordance with the new (physiological based) definition of DF announced by Codex Alimentarius in 2009. Also, sucrose is hydrolysed with a specific “sucrase” enzyme which (unlike invertase which has been used traditionally for this reaction) has no action on fructo-oligosaccharides (FOS).
* Total digestible starch (TDS) is defined as starch that is digested in a 4 h period and is part of the carbohydrate that is available for digestion and absorption in the human small intestine.

Extract high quality & quantity total RNA including miRNA
Isolate from a wide variety of animal tissues
No phenol step required – isolate all RNA in one fraction
Compatible with tissues stored in RNAlater® or Trizol®
Convenient & fast spin column format
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
This kit is suitable for the isolation of total RNA from a range of animal tissues such as liver and spleen, as well as difficult fibrous tissues such as heart, muscle, intestine, etc. Briefly, the tissue of interest is first lysed using Buffer RL, followed by treatment with the provided Proteinase K which aids in the removal of the various proteins present in fiber-rich tissues including collagen, contractile proteins, and connective tissues. The purified RNA is of the highest quality and purity, with excellent RIN values and A260/A280, and is suitable for downstream applications including qRT-PCR, RT-PCR, microarrays, NGS, and more.
The kit purifies all sizes of RNA from large mRNA, lncRNA down to microRNA (miRNA) in the same fraction without the requirement of phenol. Isolate all RNA sequences at an equal rate irrespective of size. Moreover, when the RNA sequences are small (e.g. miRNA), the column binds small RNAs regardless of their GC content.
