Measurement of adenylyl cyclase by separating cyclic AMP on silica gel thin-layer chromatography

Autor: Mami Noda, Haruhiro Higashida, Kazi Zakir Hossain, Hiroko Takahagi

Publikováno v: Analytical Biochemistry. 308:106-111

A procedure for isolation of cyclic AMP (cAMP) by thin-layer chromatography on silica gel is described. One-dimensional ascending chromatograms were developed using [H(2)O/C(2)H(5)OH/NH(4)HCO(3) (30%:70%:0.2M)] as the mobile phase. This procedure sep
