一般說明
Urea is the major end product of protein catabolism in animals. Urea is primarily produced in the liver and secreted by the kidneys. It is the primary vehicle for removal of toxic ammonia from the body. Urea determination is useful in assessing kidney function. In general, increased urea levels are associated with nephritis, renal ischemia, urinary tract obstruction, and certain extrarenal diseases (e.g., congestive heart failure, liver diseases, and diabetes). Decreased levels often indicate acute hepatic insufficiency but may also result from over vigorous parenteral fluid therapy.
特點和優勢
- The linear detection range of the kit is 50 to 1000 µM urea in the 96-well plate assay
- Compatible with high-throughput handling systems.
- Simple procedure involves adding a single working reagent, and reading the absorbance after 30 minutes. Room temperature assay. No 37 °C heater is needed.
適合性
The kit is suitable for detection of urea in biological samples such as plasma, serum, urine, bronchoalveolar lavage (BAL), and food/beverage samples such as milk.
原則
The Urea Assay Kit III is designed to directly measure urea in biological samples. In this assay, urease converts urea to ammonia and carbon dioxide. NADH is then converted to NAD+ in the presence of ammonia, α-ketoglutarate, and glutamate dehydrogenase. The decrease in optical density at 340 nm is directly proportional to the urea concentration in the sample.
