Aminooxy-PEG1-propargyl is a click chemistry PEG linker containing a propargyl group and an aminooxy group. The aminooxy group is reactive with an aldehyde or ketone group to form a stable oxime linkage. The propargyl group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

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

The Fructan Assay Kit is suitable for the specific measurement of fructan in plant extracts, animal feed and food products containing starch, sucrose and other sugars. It is used in three validated methods for the determination of fructan: AOAC method 999.03 (foods), AOAC method 2018.07 (Animal Feed) and AOAC method 2016.14 (infant formula and adult nutritionals).
New, improved procedure.
In the most recent development, a recombinant endo-levanase has been incorporated into the fructanase mixture, extending the use of the method to the measurement of levan-type fructans as are present in grasses such as timothy, cocksfoot, ryegrass and red fescue.
The method described in this booklet employs ultra-pure, recombinant enzymes and specifically measures fructans including inulin-type fructans from chicory, dahlia, jerusalem artichoke; highly branched fructans from onion and wheat stems and leaves; and levan-type fructans from pasture grasses such as timothy grass. The enzymes employed are completely devoid of contaminating enzymes active on β-glucan or gluco-oligosaccharides.
All kit reagents stable for > 2 years after preparation
Unaffected by high sucrose / reducing sugar concentrations
Fructan kits are only available from Megazyme
