A new fluorescence method for alkaline phosphatase histochemistry.


We have developed a new fluorescence method for the histochemical localization of alkaline phosphatase activity. Calcium phosphate deposited at the sites of alkaline phosphatase activity in a Gomori-type reaction are identified by calcium binding fluorochromes. The calcium binding fluorochromes calcein, calcein blue, and xylenol orange were investigated… (More)
