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 quantitative test of Microcystin in liquid samples such as water, wastewater, algal cultures, and solid samples such as fish.

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:

MutS Homolog 2 (MSH2) is a protein involved in the mismatch-repair pathway. This protein is commonly associated with hereditary non-polyposis colorectal cancer, and mutations in this gene are correlated with the development of sporadic colorectal carcinoma. Expression levels of MSH2 are abnormally low in a high percentage of patients with microsatellite instability, as well as endometrial and ovarian cancers. Use of Anti-MSH2 is optimized when paired in an IHC panel with antibodies against MSH6, MLH1, and PMS2. Reports have shown Anti-MSH2 to be useful in the detection of the protein in a number of normal and neoplastic tissues, and for identifying a loss of MSH2 in tumors that are microsatellite-unstable.
