introduction: the present study was undertaken to produce alkaline phosphatase anti- alkaline phosphatase (apaap) complex and to use it in one of the most practical methods of determining the site of antigen in tissue or in cell, i.e. apaap technique, and its comparison with similar foreign products. materials and methods: in this basic and applied study the secreted antibodies of the two hybri...

Alkaline phosphatase from human first trimester placentas was purified, characterized, and compared with alkaline phosphatases from term placenta and liver. Three forms of first trimester placental alkaline phosphatase (I, IIa, and IIb) were isolated; their relative amounts were 35%, 39%, and 26%, respectively. Phosphatases I and IIa were found to be dimers, whereas phosphatase IIb appeared to ...

introduction: this study was performed to establish a complementary method to the diagnosis of complete hydatidiform mole and its differentiation from the other cases of gestational trophoblastic disease by measuring the total (alp) and placental alkaline phosphatase (plap) specific activity. materials and methods: serum and tissue extracts from 13 patients, 13 normal non-pregnant and 30 pregna...

The optical response of an alkaline phosphatase (ALP) probe was evaluated against various bacterial species.

In rabbit skeletal muscle the polycation-stimulated (PCS) protein phosphatases [Merlevede (1985) Adv. Protein Phosphatases 1, 1-18] are the only phosphatases displaying significant activity toward the deinhibitor protein. Among them, the PCSH protein phosphatase represents more than 80% of the measurable deinhibitor phosphatase activity associated with the PCS phosphatases. The deinhibitor phos...

A cytosolic phosphoprotein phosphatase of M, = 95,000 purified from bovine cardiac muscle, which contains a catalytic subunit of M, = 35,000, is known to be associated with a Mg2+-activated p-nitrophenyl phosphatase activity. We have found that the enzyme preparation is also active toward phosphotyrosyl-IgG and -casein phosphorylated by pp60"", the transforming gene product of Rous sarcoma viru...
