TSKgel® reversed phase columns

Supplier: TOSOH Bioscience

These silica- and polymer-based columns are ideal for reversed-phase applications such as pharmaceutical drugs, forensic compounds, derivatised amino acids, carbohydrates, steroids, lipids and fatty acids. Depending on their molecular weight, peptides may be analysed with the 80 to 140 Å silica-based columns, while proteins require a larger pore size column (200 to 300 Å).

Urea ≥98%, white powder for molecular biology

Supplier: MP Biomedicals

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

5-Fluoroorotic acid ≥98%, pale yellow crystalline powder

Supplier: MP Biomedicals

FOA is a derivative of a pyrimidine precursor and is selectively toxic to yeast cells which synthesize orotidine-5’-phosphate decarboxylase. FOA has been used in a positive selection for uracil-requiring mutants(in the presence of large numbers of wild-type cells) lacking OMPdecase or OPRTase activities. This results in efficient strains for effective transformation systems.
