Definitions
- a method for isolating nucleic acids that is practical for a large number of different applications is shown in US Pat. No. 5,234,809 (Boom).
- a method for isolating nucleic acids from nucleic acid-containing starting materials by incubating the starting material with a chaotropic buffer and a DNA-binding solid phase is described there.
- the chaotropic buffers implement both the lysis of the starting material and the binding of the nucleic acids to the solid phase.
- the method is well suited for isolating nucleic acids from small sample quantities and is particularly useful in the area of isolating viral nucleic acids.
- the remaining ethanol is finally removed from the carrier material by centrifugation at 5000 rpm for 10 min or by incubation of the centrifugation column at 37 ° C. for 10 min.
- the bound plasmid DNA is detached by adding 200 ⁇ l - 300 ⁇ l of a low salt buffer (eg 10 mm Tris-HCl) at 70 ° C. and subsequent centrifugation for 5 minutes at 5000 rpm.
- the centrifugate contains the isolated plasmid DNA.
