• Up to 20ug high yield and high purity of plasmid DNA can be obtained by separation and purification with high reproducibility. • Separation and purification for up to 30 kb of plasmid DNA • Containing Lysis & Neutralization indicator (Lysis Viewer) DNA-Spin™ Plasmid DNA Purification Kit is able to perform separation and purification for high concentrated, purity plasmid DNA from bacteria using silica membrane and optimized alkali lysis buffering system. Neutralization buffering system used for pH neutralization and binding perform not only separation/purification for plasmid DNA over 30Kb, but also remove chromosomal DNA, cell debris effectively after lysis. Also, pH change through alkaline lysis method can be observed visually in real time because the product contains lysis & neutralization indicator such as Lysis Viewer (Figure 1). Product is used for either High-copy plasmid DNA or low-copy plasmid DNA and in order to perform separation and purification effectively from endA+ strain(HB101, the JM strains, NM series strains, PR series strains, etc.), Washing Buffer A is provided separately.
