Propargyl-PEG4-CH2CO2-NHS

Overview

• RNA/microRNA/DNA/Proteins are preserved for more than 2 years at room temperature in Norgen’s Urine Preservative
• 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:

• 5 cc tubes, 1 – 5 mL of urine
• 15 cc tubes, 5 – 15 mL of urine
• 50 cc tubes, 5 – 45 mL of urine
• 120 cc cup, 100 – 120 mL of urine

Description

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.

Overview

Optically clear heat sealing film which is non-peelable and non-pierceable. The seal is suitable for qPCR, optical applications and storage.

• Heat sealing offers a 100% effective method for plate sealing for a complete seal integrity, as well as being quick and cost effective
• Our ClearASeal Weld is an optically clear polymer film forming a permanent seal to polypropylene plates
• The optical clarity of this seal enables its use for sealing plates required for imaging use, including fluorescent detection methods such as qPCR and colorimetric assays
• The ClearASeal Weld forms a complete seal to a plate, enabling both low and very high temperature uses, including low temperature storage and high temperature incubations
• This seal is suitable for PCR/qPCR, even without the use of a pressurized heated lid, and is 100% effective when used in water bath thermal cyclers
• The permanent nature of this 100% effective seal renders it suitable for the storage and disposal of hazardous material
• ClearASeal Weld demonstrates a good solvent resistance and can be utilized for long term compound storage
• This seal is available as sheets, for use with manual and semi-automated sealers, such as our HeatASeal 500 Sealing Machine
• Also available in multiple roll formats compatible with specified automated heat sealers, such as our Wasp or Chameleon XT
