Product Overview
MagExtractor -Plasmid- High Efficient Plasmid purification Kit
Description
MagExtractor -Plasmid- provides a simple and reliable method for the rapid purification of plasmid DNA fromE. coli cells utilizing magnetic silica beads. This kit is based on binding properties of DNA to a silica surface in the presence of chaotropic agents (1). The purified plasmid can be used directly for automated fluorescent sequencing.
Features
- Typical plasmid yield from an E. coli cell line carrying a high-copy plasmid is approx. 3-6 µg.
- Suitable for high throughput extraction of plasmid from E. colicells. The extraction time is 10-15 minutes.
- Purified plasmid can be applied directly to sequencing, enzyme reaction, transformation, etc.
- Does not contain hazardous substances, such as phenol or chloroform.
Applications
- Plasmid purification

Principle
The selectivity of extracted nucleic acids can be changed by optimization of the binding and washing solutions. MagExtractor -Genome- (Code No. NPK-101) extracts genomic DNA from various specimens (e.g. whole blood, cultured cells or animal tissues etc.). MagExtractor -RNA- (Code No. NPK-201) extracts total RNA from various specimens (e.g. cultured cells or animal tissues). MagExtractor -Plasmid- (Code No. NPK-301) extracts plasmids from E. coli cells, MagExtractor -Viral RNA- (Code No. NPK-401) is a kit for extracting viral RNA from serum or plasma specimens. MagExtractor -Plant Genome- (Code No. NPK-501) is a kit for extracting genomic DNA from various plant specimens (e.g., leaf, cultured cells, etc.). MagExtractor-PCR & Gel Clean up- (Code No. NPK-601) extracts DNA fragments from a PCR solution, enzyme solution, or agarose gel slices.
Application Data
| Example 1. Restriction enzyme digestion of the purified plasmid DNA | |
|---|---|
| Plasmid DNA was purified from JM109 E. coli cells (from 1.2 mL cultured medium) carrying pUC18 by plasmid purification kits. Then, the purified plasmid DNA was digested by restriction enzymes. As shown in Fig.1, the purified plasmid DNA was digested completely. |
