General description

High quality double-stranded template DNA isolated from the thymus of male and female calves.

Application

Calf thymus DNA is exceptionally useful as a substrate for DNA polymerase assays, in the amplification of very long fragments and as a carrier DNA for precipitations. It was used as a standard to determine DNA content in gels and for DNA quantification by fluorescent assay.
Calf thymus DNA is exceptionally useful as a substrate for DNA polymerase assays, in the amplification of very long fragments and as a carrier DNA for precipitations.

Features and Benefits

• No nuclease activity detected after 16 h at 37 °C incubation
• High quality template DNA

Quantity

One mg DNA is approx. 20 A260 units.

Preparation Note

Prepared from highly polymerized calf thymus DNA and nicked with DNase using the method of Aposhian and Kornberg.

Reconstitution

Dissolve the DNA gently rocking overnight to a final concentration of 1mg/ml in molecular biology grade water.
