β¦ Synopsis
A method is described for covalent attachment of up to 1.1 mmol of m-aminobenzeneboronic acid/g dry weight of polyacrylamide beads. Small (4 ml) columns of the derivatized beads have been used to separate quantitatively cyclic AMP from ATP in a single-step procedure. Columns of the polyacrylamideboronate gel have been used as the basis of a convenient new assay of the soluble adenylate cyclase prepared from nuclei of Physarum polycephalum.

548) has been modified by using [3H]ATP to produce [3H]cyclic AMP and monitoring the recovery with [14C]cyclic AMP. The modified assay remains sensitive and accurate, but avoids the inconvenience and expense of using 32p.
