| Abstract: |
| Based on physical and chemical properties of cyclic nucleotydes and the
speciality of milk, cyclic nucleotides in milk were extracted with enzyme method. The
study showed that the method was moderate in condition, reasonable in technique and
easy in operation. The extracted fluid concentration of cAMP and cGMP were, by radioimmunoassay detction, 20μmol·L-1 and 0. 2μmol·L-1 respectively. |
