DBCO-PEG4-triethoxysilane is a PEG linker containing a triethoxysilane moiety and a DBCO group. Triethoxysilane is commonly used for surface modifications. DBCO group can react with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. The hydrophilic PEG chain increasse the water solubility of a compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The Urine Exosome Purification Kits provide a fast, reliable and convenient method to purify and enrich for pure intact exosomes from different urine sample volumes ranging from 250 µL to 30 mL. These kits also allow for the purification of intact extracellular vesicles (EVs) from different urine sample volumes, and these EVs are ready for any downstream application. The purification is based on Norgen’s proprietary resin.
These kits provide a clear advantage over other available methods since they do not require any special instrumentation, ultracentrifugation, precipitation reagents or any protease treatments. More importantly, the purified exosomes will not be contaminated with any other RNA-binding proteins that may contaminate your exosomal RNA, which is essential if studying exosomal RNA gene expression.
NanoSight® Analysis
Exosomes enriched with Norgen’s Urine Exosome Purification Kits can be analyzed using NanoSight® for assessing the approximate exosome size range and concentration.
Exosomal RNA Analysis
Exosomal RNA can be isolated using Norgen’s Exosomal RNA Isolation Kit from exosomes enriched using Norgen’s Urine Exosome Purification Kits for gene expression analysis using RT-qPCR, microarray or NGS and for Biomarker discovery.

Storage Conditions and Product Stability
All buffers should be kept tightly sealed and stored at room temperature. These kits are stable for 2 years after the date of shipment.
Important Note
Urine samples stored at -70°C, -20°C or at 4°C will develop some precipitation due to the aggregation of some of the highly abundant proteins in urine. Eliminating these precipitates using centrifugation or filtration may cause the loss of exosomes. Furthermore, these precipitates may affect the quality of the purified nucleic acid. We recommend the use of Norgen’s Urine Preservative when collecting urine samples, which is designed for the preservation of nucleic acids and proteins in fresh urine samples at ambient temperatures. The components of the Urine Preservative allow samples to be stored for over 2 years at room temperature with no detected degradation of urine DNA, RNA or proteins. Norgen’s Urine Preservative is available as a liquid format in Norgen’s Urine Preservative Single Dose Ampules, as well as in a dried format in Norgen’s Urine Collection and Preservation Tubes.

HiPure Insect DNA Kits provides a simple and rapid solution for total DNA extraction of insect tissue samples. This kit is based on silica gel column purification technology without toxic phenol chloroform extraction and time-consuming alcohol precipitation. The whole extraction process only takes 30 minutes. HiPure Insect DNA Kit can process tissue samples less than 10mg at a time. Hipure Insect DNA 96 kit can process 96 insect tissue samples at a high throughput. The obtained DNA can be directly used in PCR, Southern blot, viral DNA detection and other experiments.

Principles
This product is based on silica column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).

Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2–8°C, but in thiscase buffers should be redissolved before use. Make sure that all buffers areat room temperature when used.
