Brefeldin A is a fungal metabolite which is a macrocyclic lactone exhibiting a wide range of antibiotic activity. Produced by Penicillium brefeldianum. Blocks binding of the cytosolic coat protein b-COP and ARF to Golgi membranes mediated by protein G. Also blocks protein transportation into post-Golgi compartments. It activates the sphingomyelin cycle. Brefeldin A mediated apoptosis has been observed in human tumor cells. Brefeldin A reversibly inhibits the intracellular translocation of proteins in eukaryotes, e.g., during transport of proteins to the cell surface for secretion or expression. It has been reported to block the response of cultured cells to cholera toxin. In HepG2 cells, BFA induces two blocks in the secretory pathway; one at the level of the endoplasmic reticulum-Golgi juncture and the other in the trans-Golgi network. Brefeldin A is used in the studies of Brefeldin A-inhibited Guanine Nucleotide-exchange Protein, BIG2, Regulates the Constitutive Release of TNFR1 Exosome-like Vesicles. Brefeldin A (BFA) is a fungal metabolite which disrupts the structure and function of the Golgi apparatus. BFA is an activator of the sphingomyelin cycle. Brefeldin A-mediated apoptosis has been observed in human tumor cells.

Applications:
Urea is 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 and in the extraction of the mitochondrial complex. It is commonly used to solubilize and denature proteins for denaturing isoelectric focusing and two-dimensional electrophoresis and in acetic acid-urea PAGE gels. May be used with guanidine hydrochloride and dithiothreitrol (DTT) in the refolding of denatured proteins into their native or active form. Urea is used in cell or tissue culture media to increase the osmolality. Urea has also been used as fertilizer because of the easy availability of nitrogen; in animal feeds; it is reacted with aldehydes to make resins and plastics; condensed with malonic ester to form barbituric acid; used in the paper industry to soften cellulose. Biochem/physiol Actions: Urea has been shown to act as an aldosterone antagonist in the development of peanut agglutinin binding in cultured embryonic renal collecting duct epithelial cells. Urea is the principal end product of nitrogen metabolism in most mammals, formed by the enzymatic reactions of the Kreb's cycle. Typical Working Concentration: The use of 2 g/L urea in the culture of Kluyveromyces marxianus to produce a thermostable extracellular lipase has been described. Urea is typically used at a concentration of 8 M for protein denaturation or solubilization. A final concentration of 5 M urea is commonly used in molecular biology for sequencing gels. To prevent carbamylation, do not heat urea containing buffers above 37 °C

Prosci
Description:
This gene encodes a member of the aldo/keto reductase superfamily, which consists of more than 40 known enzymes and proteins. These enzymes catalyze the conversion of aldehydes and ketones to their corresponding alcohols by utilizing NADH and/or NADPH as cofactors. The enzymes display overlapping but distinct substrate specificity. This enzyme catalyzes the reduction of prostaglandin (PG) D2, PGH2 and phenanthrenequinone (PQ), and the oxidation of 9alpha,11beta-PGF2 to PGD2. It may play an important role in the pathogenesis of allergic diseases such as asthma, and may also have a role in controlling cell growth and/or differentiation. This gene shares high sequence identity with three other gene members and is clustered with those three genes at chromosome 10p15-p14.

Urea is the principal end product of nitrogen metabolism in most mammals, formed by the enzymatic reactions of the Kreb's cycle.
Urea is a mild agent usually used in the solubilization and denaturation of proteins. It is also useful for renaturing proteins from samples already denatured with 6 M guanidine hydrochloride such as inclusion bodies; and in the extraction of the mitochondrial complex. It is commonly used to solubilize and denature proteins for denaturing isoelectric focusing and two-dimensional electrophoresis and in acetic acid-urea PAGE gels. Urea is used in cell or tissue culture media to increase the osmolality. Urea has also been used as fertilizer because of the easy availability of nitrogen; in animal feeds; it is reacted with aldehydes to make resins and plastics; condensed with malonic ester to form barbituric acid; used in the paper industry to soften cellulose; used as a diuretic; enhances the action of sulfonamides; an antiseptic. Urea in solution is in equilibrium with ammonium cyanate. The form that reacts with protein amino groups is isocyanic acid. Urea in the presence of heat and protein leads to carbamylation of the proteins. Carbamylation by isocyanic acid interferes with protein characterization because isocyanic acid reacts with the amino terminus of proteins, preventing N-terminal sequencing. Isocyanic acid also reacts with side chains of lysine and arginine residues resulting in a protein that is unsuitable for many enzymatic digests. In addition, carbamylation often leads to confusing results from peptides having unexpected retention times and masses. When performing enzymatic protein digests it is important to remove urea first. Even though some enzymes will tolerate small amounts of urea, the elevated temperature used for most reactions will lead to carbamylation during the course of the digest. The urea can be removed prior to digestion by fast reversed phase chromatography, spin columns, or dialysis. Dissolve urea in deionized water to the desired concentration.For every 10 ml of solution, add 1 g of Amberlite® IRA-910.Stir for one hour at room temperature
