General description

Urea is a colorless, odorless solid. It has prism-like crystals. It forms insoluble nitrate salts with nitric acid and oxalate salts with oxalic acid. On reaction with alkanes or substituted alkanes, it affords crystal-lattice inclusion compounds.

Urea is the most commonly used slow release nitrogen fertilizer.

Application

Urea has been used in the following studies:

Synthesis of SnO₂ nanoparticles.
Synthesis of urethanes, ureides and semicarbazides.
Denaturation of protein isolated from Saccharomyces cerevisiae Y15696 strain.
Protein electrophoretic studies.

タンパク質の変性剤として、また不溶性タンパク質や変性タンパク質に対する穏やかな可溶化剤として用いられています。6 M塩酸グアニジンですでに変性された封入体などのサンプルからタンパク質を復元する用途に適しています。変性タンパク質を天然型または活性型にリフォールディングさせる際に、塩酸グアニジンやジチオスレイトール(DTT)とともに使用することができます。

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.

Performance characteristics of a new hybrid quadrupole time-of-flight tandem mass spectrometer (TripleTOF 5600).

Genna L Andrews et al.

Analytical chemistry, 83(13), 5442-5446 (2011-05-31)

The TripleTOF 5600 System, a hybrid quadrupole time-of-flight mass spectrometer, was evaluated to explore the key figures of merit in generating peptide and protein identifications that included spectral acquisition rates, data quality, proteome coverage, and biological depth. Employing a Saccharomyces

Proteomic analysis of exosomes secreted by human mesothelioma cells.

Joost P J J Hegmans et al.

The American journal of pathology, 164(5), 1807-1815 (2004-04-28)

Exosomes are small membrane vesicles secreted into the extracellular compartment by exocytosis. Tumor exosomes may be involved in the sampling of antigens to antigen presenting cells or as decoys allowing the tumor to escape immune-directed destruction. The proteins present in
