MagExtractor - Plasmid

MagExtractor-Plasmid- is a magnetic silica bead-based kit for rapid, simple and reliable purification of plasmid DNA from E. coli cells. Requiring a suitable magnetic separation stand such as the Magical Trapper (TYB-MGS-101), it exploits the property of silica surfaces to bind DNA in the presence of chaotropic agents (reference 1). Purified plasmids can be used directly in automated fluorescent sequencing.

Features

• ~3-6 ug plasmid yield from E. coli carrying a high-copy plasmid
  


• Suitable for high throughput extraction of plasmid from E. coli cells
  


• 10– 15-minute extraction time
  


• Purified plasmid can be directly utilized in sequencing, enzyme reactions, transformation, etc
  


• Does not contain hazardous substances, such as phenol or chloroform
  

Contents of kit (sufficient for 500 preparations)

• Binding Solution 130 ml x 2 (store at 4° C or room temperature)
  


• Magnetic Beads I 16 ml (store at 4° C or room temperature)
  


• Magnetic Beads II 16 ml (store at 4° C or room temperature)
  


• Suspension Solution 80 ml (store at 4° C)
  


• Lysis Solution I 80 ml (store at 4° C or room temperature)
  


• Lysis Solution II 20 ml (store at 4° C)
  


• Neutralization Solution 65 ml (store at 4° C or room temperature)
  


• Elution Solution 60 ml (store at 4° C)
  


• 5x Loading Dye 11 ml (store at 4° C)
  

Caution (Take appropriate laboratory safety measures and wear gloves when handling)

• Binding Solution contains chaotropic salt, an irritant.
  


• Lysis solution II contains NaOH.
  


• Suspension Solution contains RNase A.
  

Notes

• Magnetic Beads I are not necessary for manual use. [This reagent is used for extraction with the automated nucleic acid purification apparatus “ MFX series” ]
  


• Lysis solution I and II should be mixed at a ratio of 4:1 prior to use. This solution can be stored at room temperature for 3 weeks.
  


• Precipitates formed in “ Lysis Solution I” at low temperature can be dissolved by heating at 40° C.
  


• Purified plasmid may contain small amounts of EtOH. Plasmid DNA solutions containing EtOH sink easily into agarose gel slots using 5x Loading Dye.
