General description
High quality double-stranded template DNA isolated from the thymus of male and female calves.
Specificity
42% GC; Tm = 87 °C.
% GC is the percentage of G/C base pairs. Tm is the temperature at the midpoint of the thermal denaturation profile.
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 for DNA quantification by fluorescent assay. It was used as reference to determine the DNA content in cartilage tissue digest samples.

Features and Benefits
• No nuclease activity detected after 16 h at 37 °C incubation
• High quality template DNA
Preparation Note
Purified by anion exchange chromatography, dialyzed against a solution of 1 mM sodium chloride, 1 mM EDTA and 1 mM Trizma HCl, pH 7.5 and lyophilized at a concentration of ~2 A260 units per mL. ~20 A260 units per mg DNA.
Reconstitution
Dissolve the DNA gently rocking overnight to a final concentration of 1mg/ml in molecular biology grade water.
