MaxSignal No-Mel Milk Total Protein Kit	Bioo Scientific	1050-01	1 x 96 wells	Call for Pricing
Please sign in or sign up to order this product online. Product Detail: The MaxSignal No-Mel Milk Total Protein Assay Kit is a colorimetric assay for the determination of protein in milk, powdered milk, cream, ice cream and chocolate drink. MaxSignal No-Mel Milk Total Protein Assay Kit uses a dye-binding assay to determine protein in milk and other dairy products. The kit enables international and government regulatory agencies, food manufacturers and processors, as well as quality assurance organizations, to determine protein levels in dairy products in response to customer concerns about food safety. The test is based on a proven AOAC-approved method for milk protein determination. The MaxSignal No-Mel Milk Total Protein Assay Kit contains sufficient materials to test 42 dairy samples. The assay detects the specific binding of milk proteins to dye molecules. This detection is fundamentally different than that of some other protein determination methods (such as the Kjeldahl method) which detect protein via nitrogen and are vulnerable to contamination of amine containing impurities such as melamine. The MaxSignal No-Mel Milk Total Protein Assay Kit provides accurate, proven results even in the presence of high levels of melamine. The kit contains all reagents, including standards and buffers, required to perform the test. Materials and chemicals necessary for extraction of clenbuterol from sample material are not included in the test-kit. Procedures for extraction of clenbuterol from the samples are described in detail in the manual. BENEFITS:- • Rapid and simple method (modified version of AOAC method) less than 10 minutes • Minimal sample prep • Highly accurate and reproducible • Not influenced by the presence of melamine in samples (< 2 mg/mL in milk) Background Info: All products sold by Bioo Scientific are intended for research use only unless otherwise indicated. This product is not intended for diagnostic or drug purposes, or for use in humans.

MaxDiscovery Blood Urea Nitrogen Enzymatic Assay Kit	Bioo Scientific	5602-01	1 x 96 wells	£323.00
Please sign in or sign up to order this product online. Product Detail: The MaxDiscovery 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. MaxDiscovery 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 MaxDiscovery 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 MaxDiscovery 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. BENEFITS: • Rapid and simple method • Minimal sample prep • Highly accurate and reproducible Background Info: All products sold by Bioo Scientific are intended for research use only unless otherwise indicated. This product is not intended for diagnostic or drug purposes, or for use in humans. Product Type: Preclinical Chemistry - Blood Chemistry Additional Info: The MaxDiscovery Blood Urea Nitrogen Enzymatic Kit has the capacity for 96 determinations or testing of 42 samples in duplicate (using 12 wells for standards). Store the kit at 4°C. The shelf life is 6 months when the kit is properly stored.
Blood Urea Nitrogen Detection Kit	StressMarq	SKT-213-192	2 x 96 well	£350.00
Please sign in or sign up to order this product online. Product Detail: Quantitative colorimetric measurement of urea nitrogen Background Info: Urea is a by-product of protein metabolism by the liver, and is therefore removed from the blood by the kidneys. Urea freely filters through the glomerulous, but is reabsorbed by the renal tubules in a flow-dependent fashion. The higher the flow rate, the greater amount of urea nitrogen is cleared from circulation and eliminated through the kidneys. As a result, the level of circulating urea nitrogen, along with serum creatinine, serves as a primary measure of kidney function. Normal adult Blood Urea Nitrogen (BUN) levels should be between 7 and 21 mg urea nitrogen per 100 mL blood (mg/dL) (1). Azotemia, poor kidney function, will cause elevated BUN levels (? 50 mg/dL) and is associated with acute kidney failure or injury, severe acute pancreatitis, congestive heart failure or gastrointestinal bleeding (2-5). Azotemia also can occur with dehydration, as a result of alcohol abuse, or high protein diets. Lower than expected BUN levels are usually not clinically predictive, but are primarily associated with liver disease or malnutrition, including malabsorption and low protein diets (6). Urine and saliva are considered to be acceptable non-invasive samples for measurement of urea nitrogen (7). Serum creatinine is another metabolic waste product freely filtered by the glumerulous, but does not undergo tubular reabsorption. Its steady rate of elimination is frequently used to generate an index or ratio with BUN values for normalized evaluations. Creatinine Urinary Detection Kit (SKT-200) and Creatinine Serum Detection Kit (SKT-217) are also available from StressMarq Biosciences.

Launch Date: 17/Sep/2014 Tarriff Code: 3822.00.1090 ADR Code: Non-hazardous UN Code for transport: Non-hazardous Country of Origin: Canada Assay Type: Direct Quantitative Assay Assay Type Abbreviation: Direct Platform: Microplate Utility: Colorimetric assay used to quantitatively measure urea nitrogen in a variety of samples. Assay Overview: The Blood Urea Nitrogen (BUN) Detection Kit is designed to quantitatively measure urea nitrogen in a variety of samples. A urea nitrogen standard calibrated to NIST reference materials is provided to generate a standard curve for the assay and all samples should be read off the standard curve. Samples are mixed with Color Reagents A and B and incubated at room temperature for 30 minutes. The colored product is read at 450 nm. The concentration of urea nitrogen in the sample is calculated, after making a suitable correction for any dilution, using software available with most plate readers. The results are expressed in terms of mg/dL urea nitrogen. If samples are to be expressed in terms of mg/dL urea, the data can be converted using the multiplier 2.14. Kit Components: Clear 96 Well Plates | Urea Nitrogen Standard | Color Reagent A | Color Reagent B Precision: Inter Assay Precision: Three human samples were further diluted in water and run in duplicates in twenty-eight assays run over multiple days by five operators. The mean and precision of the calculated concentrations were: Sample 1- 1.29 mg/dL, 3.1% CV Sample 2- 2.35 mg/dL, 4.3% CV Sample 3- 5.18 mg/dL, 3.3% CV Sample Type(s): Serum | Plasma | Urine | Saliva | Tissue Culture Media Number of Samples: 88 samples in duplicate Incubation Time: 30 Minutes Sensitivity: 0.030 mg/dl Assay Range: 0.156 - 10 mg/dl Cite this Product: Blood Urea Nitrogen Detection Kit (StressMarq Biosciences, Canada, Cat # SKT-213-192) PubChem CID: 28396669 Trademark: StressXpress®
