Mal-amido-PEG4-alkyne is a short PEG linker featuring a maleimide and a terminal alkyne. Maleimide is a covalent ligand used for linking thiols such as those in cysteines residues in proteins, while terminal alkynes can be used in copper (I) click chemistry with azides on target molecules.

Overview
RNA/microRNA/DNA/Proteins are preserved for more than 2 years at room temperature in Norgen’s Urine Preservative
Compatible with most DNA, Total RNA, microRNA and protein isolation methods
Preservative is available in a single dose liquid format (ampule)
Preservative is also available in a dried format in tubes – Urine Collection and Preservation Tubes
Urine Collection and Preservation Devices are available in 4 convenient sizes: 5 cc tubes, 15 cc tubes, 50 cc tubes, and 120 cc cups
Norgen’s Urine Preservative is designed for the rapid preservation of DNA, RNA, microRNA and proteins from fresh urine samples. In addition, the Urine Preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities 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 in 2 convenient formats:
1. Urine Preservative Single Dose Ampules With this product Norgen’s Urine Preservative is supplied in a liquid format in single dose ampules. The user simply collects 5 – 50 mL of urine into a urine collection container and adds the contents of the Urine Preservative Single Dose (Cat# 18126). The urine and preservative are then mixed, and the urine nucleic acids and proteins are preserved at room temperature.
2. Urine Collection and Preservation Tubes Norgen’s Urine Preservative is also available in a dried format in Norgen’s Urine Collection and Preservation Tubes. The user simply collects urine into the tubes and mixes gently until the orange preservative pellet in the tube has dissolved. Norgen’s Urine Collection and Preservation Tubes are available in 3 convenient sizes:
Select Urine Tested with the Norgen Urine Collection and Preservation Tubes
Human Mouse Lynx Wolf Urine collected from snow
Available Sizes and Formats
Urine Collection and Preservation Tubes (50 cc) – Urine inputs from 5 – 45 mL
Storage Conditions and Product Stability All tubes should be kept tightly sealed and stored at room temperature (15 – 25°C) for up to 2 years without any reduction in performance.
Lyophilized format designed for room temperature shipping
Available in TaqMan format for analysis
Norgen’s EBV TaqMan PCR Lyophilized Kit is designed for the detection of EBV specific DNA in a real-time PCR based on the use of TaqMan® technology. The lyophilized format is designed to ship the kit at ambient temperature.
Norgen’s EBV TaqMan Lyophilized Probe/Primer and Control Set is designed for the detection of EBV specific DNA in a real-time PCR based on the use of TaqMan® technology. The lyophilized format is designed to ship the kit at ambient temperature.
All kit components should be stored at -20°C upon arrival.
Once reconstituted, repeated thawing and freezing (>2 times) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
Each kit is provided with 4 tubes of 2X PCR Master Mix and each tube is enough to run 25 reactions. It is not necessary to reconstitute all Master Mix tubes at once. The Master Mix tubes can be reconstituted as and when needed.
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
The HiPure Plasmid DNA Mega Kits combine the power of HiPure technology with the time-tested consistency of alkaline-SDS lysis of bacterial cells to deliver high-quality DNA. HiPure DNA columns facilitate the binding, washing and elution steps thus enabling multiple samples to be simultaneously processed. Plasmid DNA purified by this system is suitable for automated fluorescent DNA sequencing, restriction endonuclease digestion, transfection of mammalian cells, and other manipulations. Up to 10 mg high copy number plasmid DNA can be purified from 500 mL overnight culture.

Principle
The HiPure Plasmid procedure is based on alkaline lysis of bacterial cells followed by adsorption of DNA onto silica in the presence of high salt. The unique silica membrane used in the kit completely replaces glass or silica slurries for plasmid DNA minipreps. The procedure consists of 3 basic steps: Preparation and clearing of a bacterial lysate by alkaline method,then transfer the supernatant to column to bind DNA. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
High purity – purified plasmid can be directly used in sequencing, enzyme digestion and PCR, etc.
Fast – silica gel column purification is much faster than ion exchange
High yield – up to 10mg plasmid can be binded in one column
Low endotoxin – the obtainedplasmid can be directly used for cell transfection and animal injection, etc.
