产品描述 :Spleen exonuclease (Phosphodiesterase II) excises 3'-phosphomononucleotides from oligonucleotides having a free OH terminus. The optimum pH for the enzyme is 5.5 using succinate and phosphate buffer and pH 6-7 with 0.1 M acetate buffer. The enzyme is assayed using a modification of the Hilmoe (Biochem. Prep., VII, (Meister, A., ed.), John Wiley and Sons, NY, 105, 1961) technique
