Deoxyribonucleic Acid and Related Products Product Information

Worthington offers DNA purified from these sources:

Calf thymus: (Code: DNA) Prepared and purified by a method developed at Worthington to have lower protein and RNA contamination than most other commercial preparations. This highly polymerized DNA is an excellent substrate for deoxyribonuclease. A sodium salt, it must be converted by adding magnesium ions to be susceptible to DNase.

Calf thymus DNA, covalently bound to cellulose is also available:
DNA Cellulose, Double-Stranded
(Code: DNACELDS)
DNA Cellulose, Single-Stranded (Code: DNACELSS)

Salmon Testes: (Code: SDNA) Prepared by a modification of the method of Emanuel and Chaikoff, J. Biol. Chem., 203, 164, (1953). A minimum of 75% native nucleic acid.

Salmon Testes DNA, Denatured & Fragmented (Code: SDNAD) is also available. Prepared by mechanical shearing and heat denaturation.

Escherichia coli: (Code: DNAEC) Isolated as described by Marmur, J. Mol. Biol., 3, 208, 1961.

Lambda phage DNA (Code: DNAL) is prepared from CsCl purified phage and is purified to an A260/A280 ≥1.8. Homogeneous in agarose gel electrophoresis. A solution in 10 mM Tris-HCl pH 8.0 with 1 mM EDTA.

DNA fragments prepared by restriction endonuclease digestion of purified lambda DNA are available (Codes: DNALBSTE; DNALECOR; DNALHIND). Supplied as solutions in 10 mM Tris-HCl pH 8.0 with 1 mM EDTA.

Technical Note: One A260 unit = 50 µg DNA.

Stability/Storage: DNAL: Storage buffer 10 mM Tris-HCl, pH 8.0 containing 1 mM EDTA. Store at -20°C.  Once thawed keep at 2-8°C.
