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.

Rapid isolation of both small and large species of DNA from urine
Convenient spin column format
Effective removal of PCR inhibitors
Purified DNA is highly suited to sensitive downstream applications
Allows for the purification of viral DNA from urine
Both high molecular weight DNA (greater than 1 kb in size; mostly cell associated) and the smaller DNA (150 – 250 bp; derived from the circulation) is effectively isolated and purified using a rapid and convenient spin column protocol. This kit can be used to isolate DNA from a broad range of viruses in urine as well. Salts, metabolic wastes, proteins and other contaminants are removed to yield inhibitor-free DNA for use in sensitive applications. The DNA is of excellent quality for various downstream applications such as PCR, qPCR and DNA fingerprinting, methylation studies and more.
This kit provides a fast, reliable and simple procedure for isolating DNA from urine volumes ranging from 50 μL to 1.75 mL of urine. Multiple samples can be processed in 30 minutes.
Urine DNA Isolation Kit (Slurry Format)
This kit provides a fast, reliable and simple procedure for isolating DNA from urine volumes ranging from 3 mL to 25 mL. Multiple samples can be processed in 30 minutes. Multiple samples can be processed in 45 minutes.
Urine DNA Isolation Maxi Kit (Slurry Format)
This kit provides a fast, reliable and simple procedure for isolating DNA from urine volumes ranging from 25 mL of urine up to 80 mL. Multiple samples can be processed in 45 minutes.
Background
DNA found in urine can be divided into 2 basic categories. The larger species, genomic-DNA (gDNA), is generally greater than 1 kb in size, and appears to be derived mainly from exfoliated cells. The second species is smaller, generally between 150 and 250 bp (apoptotic-DNA), and derives, at least in part, from the circulation. The second species is also considered as an RNA/DNA hybrid as reported by Halicka et al. (2000). Both types of DNA can be isolated reliably using this kit.
Storage Conditions and Product Stability All buffers should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm up Slurry B1 and Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed. Slurry B1 contains a grey resin that will not dissolve when warmed.
