Acid phosphatase: New developments

Research output: Contribution to journalArticlepeer-review


Acid phosphatase was the first “tumor marker” to be measured in the blood, and over 40 years have passed since an elevation of the serum acid phosphatase level was observed in patients with prostatic carcinoma. However, significant elevations in the level of this enzyme have been observed in other diseases, as well as elevations of other tissue phosphatases. Many improvements in the colorimetric technique have been introduced, but none has been used successfully to detect the tissue origin of this ubiquitous enzyme. The finding that prostatic acid phosphatase is antigenically distinct from acid phosphatase of other tissues opened a new horizon in the measurement of acid phosphatase in prostatic cancer. On the basis of this immunochemical specificity, several immunoassays have been employed for determining the prostatic acid phosphatase level.
