Application: | Urea has been used: • to adjust the urea nitrogen concentration to a preferred range in blood reservoir for evaluating the dialyzer urea clearance • to prepare standards to measure urea synthesis • to prepare standards for blood urea nitrogen assay |
Application: | Used for the denaturation of proteins and as a mild solubilization agent for insoluble or denatured proteins. Useful for renaturing proteins from samples already denatured with 6 M guanidine chloride such as inclusion bodies. May be used with guanidine hydrochloride and dithiothreitrol (DTT) in the refolding of denatured proteins into their native or active form. |
Biochem/physiol Actions: | Urea participates in the metabolism of nitrogenous substances. It serves as a nitrogen source, when used in fertilizers. Urea is used in manufacturing chemical compounds. It is widely used in the agricultural industry as a fertilizer as well as an animal feed additive, which is used as a nitrogen supplement in animal husbandry. Urea has adverse effects on seed germination, seedling growth and early plant growth in soil. |
General description: | Urea is a colourless organic compound, without any odour. It is easily soluble in water. |
