 GenElute™ Plant Genomic DNA

Plant Molecular Biology
 

Description: With the GenElute Plant Genomic DNA Purification Kit, high quality genomic DNA can be purified from a variety of plant species (Table 1).

The kit contains all the reagents, columns, and tubes necessary to isolate genomic DNA from up to 100 mg of fresh (Figure 1) or 20 mg of freeze-dried plant tissue. Plant tissue is disrupted by grinding in liquid nitrogen, and DNA is released with detergent and chaotrope. Proteins, polysaccharides, and cell debris are eliminated with a 10 minute precipitation procedure followed by centrifugation through a filtration column, included in the kit. The genomic DNA is purified further by a silica bind-wash-elute procedure in microcentrifuge spin columns. Purified DNA (Figure 2) is ready for downstream applications such as PCR (Figure 3), Restriction Endonuclease Digestions, Cloning and Southern Blots.

GenElute Plant Genomic Kits Figure 1. Purified genomic DNA (0.4 µg/lane) was analyzed on a 0.8% agarose gel. Sigma, membrane-based; Supplier A, resin-based; Supplier M, solution based; Supplier Q, membrane-based. The Sigma prep shows the best yield of high molecular weight DNA, with less shearing (downward smear) than supplier Q. Markers are lambda DNA digested with EcoRI / Hind III digest.

Note: RNA contamination present in DNA isolated using the kits from both Supplier A and M (smear below 0.6 kb).

Figure 2. Purified genomic DNA (0.4 µg/lane) was analyzed on a 0.8% agarose gel.

Note: The DNA prepared from each species migrates as a tight band with little downward smearing, indicating that the majority is high molecular weight (> 21 kb).
No low molecular weight material is detected (< 0.6 kb), indicating that RNA has been eliminated without the use of RNase A digestion. Markers are lambda DNA Eco RI / Hind III digest.

Plant Genomic PCR Gel
Figure 3. Genomic DNA from soybean leaves was purified using the GenElute Plant Genomic DNA Miniprep Kit. A 5 µl aliquot of eluate was used as template in a 20 µl total PCR reaction for 30 cycles. A 5 µl aliquot of each PCR reaction was resolved on a 1% precast agarose gel (Product Code 5722). The PCR marker (M) used (Product Code P9577) ranged from
50 bp to 2 kb.
