Propargyl-PEG8-amine is a heterobifunctional reagent consisting of a propargyl group and an amine group. The amine group can form amide bonds with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The propargyl group can form triazole linkage with azides in copper catalyzed Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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:

This kit provides a rapid spin column method for the purification of total DNA from a broad spectrum of bacteriophages propagated in bacteria grown in liquid cultures. The DNA is isolated without the use of phenol, chloroform or cesium chloride banding procedures. The spin-column based procedure is rapid and can be completed in less than 45 minutes. The kit is highly efficient for processing small volumes of phage supernatant (500 µL – 1 mL) and with the optional DNase and Proteinase K treatments phage DNA yields are maximized while host DNA contamination is minimized. Purified total phage DNA is of the highest integrity, and can be used in a number of downstream applications including PCR, qPCR, Restriction Fragment Length Polymorphism (RFLP), sequencing, cloning, Southern Blot and more.
