Gf. Huhn et al., PURIFICATION OF NUCLEOSIDE-5'-DIPHOSPHATES - A NEW ION-EXCHANGE METHOD, Separation science and technology, 28(11-12), 1993, pp. 1959-1970
Inosine- and uridine-5'-diphosphates can be purified by ion-exchange c
hromatography utilizing a new ion-exchange method where Type 1 ion-exc
hange resins and the absorbed nucleoside polyphosphates are changed to
the basic form by rinsing the column with dilute sodium hydroxide and
subsequently eluting with dilute hydrochloric acid and sodium chlorid
