Studies on Alkaline Phosphatase
European Journal of Biochemistry, 1972The three common homozygous variants of human placental alkaline phosphatase, types F1, S1 and I1 were partly purified and the concentration of active sites determined using a stopped‐flow procedure. A comparison of the variant steady‐state activities indicated that any differences in catalytic‐centre activity are marginal, both at alkaline pH (with 4 ...

Phosphoprotein-phosphatase activity associated with human placental alkaline phosphatase
Biochemical and Biophysical Research Communications, 1976Abstract Human placental alkaline phosphatase, a marker protein for some nontrophoblastic neoplasms, was found to have phosphoprotein phosphatase activity. This was demonstrated by the dephosphorylation of 32P-labeled histones, protamine, glycogen synthetase, casein, and phosvitin at various pH values.

Urinary Alkaline Phosphatase Activity
JAMA, 1963THE RECOGNITION and removal of an inhibitor(s) of lactic dehydrogenase (LDH) activity of human urine resulted in the development of a method useful for the detection and diagnosis of carcinomas of the kidney and bladder.1,2These discoveries suggested that other enzymes previously thought to be absent or inconsistently present in urine might similarly ...

Serum alkaline phosphatase activity in cattle
Clinica Chimica Acta, 1971Abstract Some biochemical properties of isoenzymes of alkaline phosphatase were examined in extracts of bovine tissues. The value of isoenzyme analysis of alkaline phosphatase activity in bovine serum as a diagnostic aid was studied. Three techniques were compared for routine determination of alkaline phosphatase activity in bovine serum.

SERUM ALKALINE PHOSPHATASE ACTIVITY IN SHEEP
Australian Journal of Experimental Biology and Medical Science, 1974SummaryThe influence of age and the R‐r‐i blood group system upon serum alkaline phosphatase activity is described.Changes in isoenzyme patterns of alkaline phosphatase activity, as determined by use of amino acid inhibitors and heat, were seen from birth to day 1 of life, with increasing age and between animals of the R and r blood group.

ALKALINE PHOSPHATASE ACTIVITY IN MOUSE LYMPHOMA TISSUE
Australian Journal of Experimental Biology and Medical Science, 1962SUMMARYAlkaline phosphatase (AP) levels were low (2 K.A. units/gm.) in normal AKR thymuses and the enzyme activity was not localised in the lymphoid cells. AP levels were slightly elevated in preleukaemic AKR thymuses. In AKR thymic lymphomata, AP levels were usually elevated, but the levels in individual mice were highly variable (0·3–88·5 K.A, units ...

Colchicine increases hepatic alkaline phosphatase activity
Biochimica et Biophysica Acta (BBA) - General Subjects, 1977In vivo administration of colchicine increases the activity of alkaline phosphatase significantly in the livers of rats. Prior treatment with cycloheximide prevented the induction of the enzyme by colchicine suggesting that de novo protein synthesis was essential for the effect of colchicine on alkaline phosphatase activity. Bilateral adrenalectomy did

Alkaline phosphatase activity in cultured meningioma cells
Acta Neuropathologica, 1982The specific activity of alkaline phosphatase in cultured human meningioma cells varies over a relatively wide range. There is no correlation between the levels of activity and the histological type of meningioma from which the cultures were derived.

Measurement of Alkaline Phosphatase Activity
1979This chapter will discuss some practical aspects of alkaline phosphatase assays. While the remarks are based predominantly on experience gained with human blood serum, many of the points raised are also applicable to the assay of alkaline phosphatases from other sources.

Albumin Preparations and Placental Alkaline Phosphatase Activity*
Transfusion, 1973A 68‐year‐old male with nephrotic syndrome due to diabetic glomerulosclerosis was found to have high serum alkaline phosphatase after albumin infusions. By examining several albumin preparations, certain products were found to contain as high as 200 Sigma units of alkaline phosphatase per ml. By disc electrophoresis and heat treatment (56 C for 30 min),
