Description: The E.Z.N.A.® Plasmid Maxi Kit is the maxi scale system to deliver high-quality plasmid DNA using the spin column format, without costly accessories. The HiBind® DNA Maxi column facilitates the binding, washing, and elution steps, thus enabling multiple samples to be simultaneously processed. Although yields vary according to plasmid copy number, <i>E.coli</i> strain, and conditions of growth, 50 to 200 ml of overnight culture in LB medium typically produces 0,5 to 1 mg of high copy number plasmid DNA. Up to 500 ml of culture may be processed when working with low copy number plasmid. The product is suitable for automated fluorescent DNA sequencing (typical reads exceed 800 bp), restriction enzyme digestion, transfection of mammalian cells, transcription<i> invitro</i>, and other applications.

Description: E.Z.N.A.® Plasmid Midi Kit offers a novel and reliable method of isolating up to 200 µg of plasmid DNA in less than 60 minutes. This kit combines HiBind® membrane technology with the time-tested consistency of alkaline SDS lysis of bacterial cells to deliver high-quality plasmid DNA. The DNase/RNase-free HiBind® DNA midi columns operate by eliminating time consuming phenol-chloroform extractions and alcohol precipitations. Plasmid purification using the E.Z.N.A.® Plasmid Midi Kit follows a simple bind-wash-elute procedure thereby making it possible for multiple samples to be processed. Although yields vary according to plasmid copy number, <i>E.coli </i>strain, and conditions of growth, 50 ml of an overnight culture in LB medium will typically produce 200 µg of high-copy number plasmid DNA. When working with low-copy number plasmids the starting culture volume can be increased up to 100 ml. High-quality DNA is ready for immediate use in routine molecular biology applications, such as automated fluorescent sequencing, restriction enzyme digestion, and transfection screening.

Catalog Number: (1B1301-KIT)

Supplier: VWR Chemicals

Description: The Protein Precipitation Kit utilises a simple trichloroacetic acid (TCA) based method to precipitate proteins in complex mixtures. Only protein in the sample is pelleted, while interfering salts and surfactants remain in the supernatant. A gentle acetone wash removes TCA and co-precipitants allowing the end-user to recover the protein in a small volume of buffer.

Description: These loggers travel with shipments to track relative humidity and temperature. For complete flexibility, the user-defined recording interval may be set based on the number of desired days to log (from 4 hours to 365 days) or the desired time interval (from every 2 seconds to every 24 hours). To ensure that no data is lost, once memory is full the thermometer/hygrometer will stop logging data (data will not be overwritten).
