Introduction

The HiPure Midi system provides a fast, simple, and cost-effective plasmid DNA midiprep method for routine molecular biology laboratory applications. HiPure Midiprep Kits use silica membrane technology to eliminate the cumbersome steps associated with loose resins or slurries. Plasmid DNA purified with Mini Kits is immediately ready for use. Phenol extraction and ethanol precipitation are not required, and high quality plasmid DNA is eluted in a small volume of Tris buffer or water.

Principle

The HiPure Plasmid procedure is based on alkaline lysis of bacterial cells followed by adsorption of DNA onto silica in the presence of high salt. The unique silica membrane used in the kit completely replaces glass or silica slurries for plasmid DNA minipreps. The procedure consists of 3 basic steps: Preparation and clearing of a bacterial lysate by alkaline method，then transfer the supernatant to column to bind DNA. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).

Advantages

• High purity – purified plasmid can be directly used in sequencing, enzyme digestion and PCR, etc.
• Fast – silica gel column purification is much faster than ion exchange
• High concentration – easily obtain concentrations >1000ng/μl
• Small amount large extraction – using a small amount of column to achieve a large extraction yield (500μg)
• Low endotoxin content – the obtained plasmid can be directly used in cell transfection and animal injection

Storage and Stability

The kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. If any precipitates form in the buffers, warm at 37℃ to dissolve. After addition of RNase A and optional LyseBlue reagent, Buffer P1 is stable for 6 months when stored at 2–8°C.

The α-D-Glucuronidase test kit is a simple, reliable and accurate method for the measurement and analysis of α-D-glucuronidase in various enzyme preparations. The kit contains a pure aldotriouronic acid substrate and an α-D-glucuronidase (GH67) control enzyme.

New, improved substrate.

This kit contains highly purified, borohydride reduced aldotriouronic acid with a terminal α-D-glucuronic acid substitution, which is an excellent substrate for α-D-glucuronidases from GH67. This substrate can be also used for the measurement of α-D-glucuronidases from GH115, however the rate of hydrolysis compared to GH67 is reduced. Previously this kit contained a mixture of borohydride reduced aldouronic acids (tri:tetra:penta).
