Description
Ultrapure dUTP (2´-Deoxyuridine, 5´-Triphosphate) supplied as sodium salt in purified water (pH 8.5). dUTP can be used in place of dTTP in PCR and RT-PCR protocols to prevent carryover from previous amplifications. The substitution of dUTP for dTTP in PCR results in uracil-containing PCR products that are suitable for most standard applications. The enzyme uracil-N-glycosylase (UNG, also referred to as UDG) can be added to a PCR premix to excise uracil from any contaminating PCR product, thereby preventing false positives. Each lot of dUTP is tested to ensure specific DNA amplification and the absence of nuclease activity.

Blood Urea Nitrogen Enzymatic Kit is a microplate-based colorimetric
assay for the determination of urea in serum samples produced from blood. Blood urea nitrogen (BUN) is an important marker for normal kidney and liver function. Elevation of BUN levels is often an indication of intestinal and kidney obstruction and cardiac failure. Decreased BUN levels are often associated with kidney and liver damage. BUN is also a very useful tool
for preclinical investigation of experimental drug formulations and BUN levels are commonly used to monitor and attenuate the toxic effects of experimental drug formulations in rodents.
Blood Urea Nitrogen Enzymatic Kit uses an enzyme-based assay to determine urea in liquid samples such as serum. The test is based on a highly proven method for urea determination. The Blood Urea Nitrogen Enzymatic Kit contains sufficient materials to test 42 samples in duplicate. The assay utilizes urease, a metabolic enzyme, to specifically detect urea in serum. The Blood Urea Nitrogen Enzymatic Kit provides rapid, accurate, proven results even in complex liquid mixtures. The limit of detection for the test is 8 ppm urea for serum. The linear range of the assay is 8 – 200 ppm analyte.

Norgen’s Viral Transport Medium is formulated to transport samples that are presumably infected with a virus. Viral Transport Medium is manufactured based on CDC formula and is offered in bulk to provide an option to readily assemble swab collection devices for sample collection.
Norgen’s Viral Transport Medium (VTM) is designed for safe and efficient transport of viral samples, including but not limited to those from nasal, throat, and other swabs. The VTM contains a balanced mix of Hank’s Balanced Salt Solution (HBSS), heat-inactivated fetal bovine serum (FBS), gentamicin sulfate, and amphotericin B to preserve the viability of viruses and prevent the growth of contaminating bacteria and fungi. The medium ensures the stability and viability of viruses, chlamydia, and mycoplasma for analysis using different techniques. In addition, the Viral Transport Medium eliminates the need to immediately process or freeze samples.
Storage Conditions and Product Stability
The Viral Transport Medium can be stored at 2-8°C for up to 1 year from the date of manufacturing without any reduction in performance.
