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:

DBCO STP ester is a water-soluble reagent with a terminal DBCO group and a STP ester group. DBCO STP ester that can be used for the modification of peptides, antibodies, proteins, and other molecules containing the amine group. The STP esters are excellent alternatives to conventional N-hydroxysuccinimide (NHS) esters for coupling reactions in aqueous environments. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. Reagent grade, for research use only.

Microcystin are a class of hepatotoxins produced by blue-green algae such as Microcystis aeruginosa. Microcystin-LR is the most common of the over 50 different congeners. Cyanobacteria can produce microcystin in large quantities during an algae bloom which then pose a major threat.
This kit can be used for Congener-Independent quantitative test of Microcystin in liquid samples such as drinking, ambient and waste water and algal cultures.
Additional Quality Control, Calibration Verification, and Spiking Solution materials can be obtained separately in optional Supplemental Pack for Method 546 (catalog # EL2024-Q).
