Remove the MN Wash Plate and the waste container from the manifold base and place the NucleoSpin Binding Plate on top of the manifold. Are you doing COVID-19 related research? The size of the DNA fragment is determined from its electrophoretic mobility. The lysate must be handled gently after addition of buffers P2 and P3 to prevent shearing of chromosomal DNA. Researchers can insert DNA fragments or genes into a plasmid vector, creating a so-called recombinant plasmid. Plasmid Buffers are used in plasmid DNA purification procedures. Neutralization buffer (3.0 M potassium acetate, pH 5.0) neutralizes the resulting lysate and creates appropriate conditions for binding of plasmid DNA to the silica membrane column. Precipitated protein, genomic DNA, and cell debris are then pelleted by a centrifugation step and the supernatant is loaded onto a column. All QIAprep Miniprep Kits can be used for preparation of low-copy number plasmids and cosmids up to 50 kb. At a specified, low voltage, the migration rate of small linear DNA fragments is a function of their length.
