MagExtractor -Genome- High Efficient Genomic DNA purification Kit
Description
MagExtractor -Genome- provides a simple and reliable method for the rapid purification of genomic DNA from various specimens (e.g. whole blood, cultured cells or animal tissues etc) using magnetic silica beads. This kit is based on binding properties of DNA to a silica surface in the presence of chaotropic agents (1)(2). The purified genomic DNA can be used directly for PCR experiments.
Features
Can be applied to extraction of DNA from whole blood specimens. A leukocyte or lymphocyte separation step is not necessary.
Does not contain hazardous substances, such as phenol or chloroform.
Purified DNA samples can be applied directly to other methods, such as PCR, etc.
Suitable for high-throughput extraction of genomic DNA from various specimens.

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. Purification of genomic DNA from whole blood
Genomic DNA was purified from 100 mL whole blood specimens (human) using various purification kits. The purified genomic DNAs were analyzed by normal electrophoresis and pulse-field gel electrophoresis methods. As shown in Fig. 1, highly purified genomic DNA was successfully purified by MagExtractor -Genome- with high yield. Purified genomic DNAs from other company’s kits (company A and C) were estimated to contain proteins (assayed by absorbance at A260/280 nm (Table 1)). The average size of the purified genomic DNA by MagExtractor -Genome- was approximately 50 kb (Fig. 2).

Example 2. Purification of genomic DNA from cultured cells
Genomic DNA was purified from HeLa cells (5×10 cells) using various purification kits. As shown in Fig. 1, highly pure genomic DNA was successfully purified by MagExtractor -Genome- with high yield. Purified genomic DNAs from other companies’ kits (company A, B and C) were estimated to contain RNA or proteins (Fig. 1, Table 1).

Example 3. PCR using purified genomic DNA samples
Genomic DNA was purified from 100 mL whole blood specimens from unrelated human donors using the MagExtractor kit. The yields and A260/280 nm (purity) were in the range of 1.4-2.2 µg and 1.83-1.84, respectively. PCR of the highly polytypic VNTR locus (MCT118) was performed using 1/20 volume of purified genomic DNA by Taq DNA polymerase. As shown in Fig. 2, distinct and highly polymorphic amplified bands were detected.
