This product is a double-stranded alternating DNA copolymer, although it is possible for single strands to be present. The sequence of each strand is an alternating sequence of dAdTdAdTdAdT….. or dATdATdATdAT… since dT (deoxythymidylic acid) and T (thymidylic acid) are the same.

What is the difference between Poly(deoxyadenylic-thymidylic) acid sodium salt Products P0883 and P5782?
1 answer-
Prod. No. P0883 is from a different supplier than Prod. No. P5782. Chain lengths for both products can vary from batch to batch. According to information from our suppliers, the A250/A260 ratios are similar, but the A280/A260 ratio for Prod. No. P0883 will be slightly higher than that of Prod. No. P5782.

In what should Product P0883, Poly(deoxyadenylic-thymidylic) acid sodium salt, be dissolved?
1 answer-
Per our supplier, to maintain a double stranded configuration of the polymer in solution, it should be rehydrated with a neutral buffer containing 100 mM NaCl. After reconstitution, the polymer solution should be stored at -20°C.
