일반 설명
The GenElute Mammalian Genomic DNA Purification Kit provides a simple and convenient method to isolate pure, high molecular weight DNA from a variety of mammalian sources. These kits use a silica-based membrane, specially selected for genomic DNA purification, in a convenient spin column format.
The starting materials are lysed in a chaotropic salt-containing solution to ensure the thorough denaturation of macromolecules. The addition of ethanol causes DNA to bind when the lysate is spun through a silica membrane in a microcentrifuge tube. After washing to remove the contaminants, the DNA is eluted in 200 μL of a Tris-EDTA solution. The expected yields of genomic DNA will vary depending on the amount and type of starting material used. DNA purified with the kit has an A260/A280 ratio between 1.6 and 1.9 and can be up to 50 kb in length.
The purified genomic DNA is ready for immediate use in downstream applications such as restriction digest, PCR, southern blots, and sequencing reactions.
