DNA (Deoxyribonucleic Acid), Sodium Salt (Calf Thymus)

Specially prepared to be low in protein content but highly polymerized. Suitable as a substrate for deoxyribonuclease. This DNA is an excellent substrate for DNase. A sodium salt, it must be converted by adding magnesium ions to be susceptible to DNase.||• Low protein and RNA content|• Characterized by a high polymerization factor||Source:|Calf thymus isolated by the method established by Marmur.||Form:|Supplied as a highly purified dried powder||Hyperchromicity:|≥27%||Absorbance Ratio (A260/A280):|≥1.8||Recommended Storage Buffer:|10mM Tris-HCl. pH 8 containing 1mM EDTA (TE Buffer)||Quality Control:|SDS-PAGE||Storage and Stability:|Lyophilized powder may be stored at 4°C.
