MagExtractor - Plasmid

Toyobo

Catalog No.: TYB-NPK-301

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.
