Acid Phosphatase in Eyes with Pseudoexfoliation
American Journal of Ophthalmology, 1980We studied the activity of acid phosphatase in the anterior segment of the eye with pseudoexfoliation histochemically and biochemically. Light and electron microscopic histochemistry revealed lead precipitates indicating acid phosphatase activity in pseudoexfoliative materials.

Acid phosphatase in Enteromorpha
Phytochemistry, 1972Abstract Extracts of the alga Enteromorpha linza hydrolysed glucose-6-phosphate, p -nitrophenylphosphate 2′-, 3′-, and 5′-adenosine monophosphates with an optimum at pH 5. Cytidine and uridine-5′-nucleoside diphosphates, and 2′-, and 3′-adenosine monophosphates were relatively poorly hydrolysed.

Gel isoelectric focussing of pig liver extracts revealed multiple bands of acid phosphatase activity. The three major forms were separated by ion-exchange chromatography, and appear to be of lysosomal origin. Neuraminidase treatment converted one fraction to a form resembling one of the two remaining fractions; these differ in other significant ways ...

ACID PHOSPHATASE IN THE SENILE BRAIN
Archives of Neurology And Psychiatry, 1949GOMORI1and Takamatsu2in 1939 showed that the presence of phosphatase can be demonstrated in tissue sections. Their work referred to alkaline phosphatase; however, later, Gomori3described a method by which acid phosphatase, too, can be made visible in sections. Wolf, Kabat and Newman4examined the nerve tissue for acid phosphatase.

Acid phosphatases are ubiquitous enzymes present in almost all tissues. Isoenzyme 2 and the antigenically related but deglycosy-lated isoenzyme 4 are found predominantly in prostatic tissue. The association of elevated acid phosphatase with carcinoma of prostate is of long standing but the specificity of kinetic enzyme assays has been less than perfect.

Publisher Summary This chapter discusses the extraction of prostatic acid phosphatase, red cell acid phosphatase, liver acid phosphatase, spleen acid phosphatase, and acid phosphatase in serum. Acid phosphatase did not hydrolyze S -substituted monoesters of phosphorothioic acid but did hydrolyze O -substituted monoesters of phosphorothioic acid ...

Acid phosphatases of human erythrocytes
Archives of Biochemistry and Biophysics, 1965Abstract Two acid phosphatases of human erythrocytes have been detected and separated by means of gel filtration on polymerized dextrans. The two enzymes, given the trivial names E 1 phosphatase and E 2 phosphatase, differ in molecular weight, pH optima, metal requirements, and type of inhibitors.
