Liquid-chromatographic determination of isoenzymes of alkaline phosphatase in serum and tissue homogenates. 1986

E Schoenau, and K H Herzog, and H J Boehles

We describe a new method for separating alkaline phosphatase (AP) isoenzymes by means of "high-performance" liquid chromatography. Isoenzymes are eluted from the column (Mono Q HR 5/5, a strong anion-exchanger) with a stepwise gradient of LiCl. The isoenzymes originating from small intestine, bone, liver, and bile were identified by use of tissue homogenates, pathological sera, and heat inactivation.
