丙烯酰胺 40% in aqueous solution, Acryl 40™, Proteomics Grade

目录号: (VWRCM121-500ML)

供应商: VWR Chemicals

描述: VWR offers an extensive line of acrylamide and bis-acrylamide pre-weighed powder blends, pre-mixed stock solutions, and ready to use solutions for customised polyacrylamide gel electrophoresis of proteins and PAGE of nucleic acids. Our ultra-pure (>99,9%) acrylamide and bis-acrylamide powders provide the flexibility to prepare solutions having concentrations and ratios for all electrophoresis applications. Liquid blends minimise the handling of neurotoxic acrylamide.

琼脂糖, Electran, resolution_high, low melting Electrophoresis

供应商: VWR Chemicals

描述: Agarose high resolution is optimised to give exceptional separation on agarose of nucleic acid fragments below 1000 base pairs, and differing by only a few base pairs. It retains the low gelling characteristics of the standard Agarose HR, and offers significantly increased gel strength at the expense of a higher melting temperature. This results in gels which are flexible and easy to handle. These properties make it the agarose of choice for analytical gel separations to check the quality and size of amplified fragments, and for use in restriction mapping involving small digestion fragments.

溴化乙啶 0,625 mg/l aqueous solution, Biotechnology Grade

目录号: (VWRCE406-5ML)

供应商: VWR Chemicals

描述: Ethidium bromide solution is a fluorescent stain for visualising nucleic acids in solution or in electrophoresis gels. The solution is provided at a concentration of 0,625 mg/ml. A final working concentration of 0,5 g/ml is easily obtained by adding one drop of solution to 50 ml of molten agarose, running buffer or staining buffer. Ethidium bromide solution in dropper bottles may be stored at room temperature for up to one year.
