The HiPure Mini system provides a fast, simple, and cost-effective plasmid DNA miniprep method for routine molecular biology laboratory applications. HiPure Plasmid Mini 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.
Compared to other domestic products, Magen was the first to solve the stability problem of the column. Many other brands have unstable extraction concentrations, and the longer the time, the more unstable the column becomes. However, in our test of Magen kit, the quality and yield of plasmid extraction still remain stable after 5 years’ storage. For different customers, our kits can be customized. For example, Classic type is suitable for customers with low copy or unclear plasmid types. The rapid type is suitable for customers with high copy plasmids. Compared to many other brands, the plasmid DNA extracted by Magen has a longer preservation time and more thoroughly RNA removal.

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).

Varicella zoster virus (VZV) is one of eight herpes viruses known to infect humans and other vertebrates. VZV commonly causes chicken-pox in children and both shingles and postherpetic neuralgia in adults. Primary VZV infection results in chickenpox, which may rarely result in complications including encephalitis or pneumonia. VZV, like other herpes viruses, remains dormant in the nervous system of the infected person, and in 10-20% of cases the VZV reactivates later in life producing a disease known as herpes zoster or shingles. Serious complications of shingles include postherpetic neuralgia, zoster multiplex, myelitis, herpes ophthalmicus, or zoster sine herpete.

Storage Conditions and Product Stability
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
