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:

Cell membrane preparations containing nicotinic AChRs that are ligand-gated ion channels that form pores in cells plasma membranes, mediating fast signal transmission at synapses. Nicotinic AChRs are involved in a wide range of physiological processes, and can be either neuronal or muscle-type. The membrane preparations we have developed are suitable for receptor binding assays in which muscle type nicotinic AChRs are needed. The membranes are tested in several functional binding assays and quality testing criteria to meet binding specifications.

The α-D-Glucuronidase test kit is a simple, reliable and accurate method for the measurement and analysis of α-D-glucuronidase in various enzyme preparations. The kit contains a pure aldotriouronic acid substrate and an α-D-glucuronidase (GH67) control enzyme.
New, improved substrate.
This kit contains highly purified, borohydride reduced aldotriouronic acid with a terminal α-D-glucuronic acid substitution, which is an excellent substrate for α-D-glucuronidases from GH67. This substrate can be also used for the measurement of α-D-glucuronidases from GH115, however the rate of hydrolysis compared to GH67 is reduced. Previously this kit contained a mixture of borohydride reduced aldouronic acids (tri:tetra:penta).
