an aid in the diagnosis of prostate cancer since 1936 when Gutman et a!. (13) first reported the relationship between serum acid phosphatase and prostate cancer. They found that serum acid phosphatase activity markedly increased in patients with prostate carcinoma, especially in those with bone metastasis. Elevated serum acid phosphatase activity has been reported in 70 to 90% of the patients w...

Although acid B-glycerophosphatase (acid phosphatase, EC 3.1.3.2) has long been the chosen marker for lysosomes in cell fractionation (de Duve et al., 1955; Reid, 1972), there are differences in distribution between acid phosphatase and other hydrolases when rat liver is fractionated. In particular, acid-phosphatase-rich lysosomes sediment more slowly (Sellinger et a/., 1960; Rahman & Cerny, 19...

The objective of this research is to identify Arabidopsis thaliana genes encoding acid phosphatases induced by phosphate starvation. Multiple alignments of eukaryotic acid phosphatase amino acid sequences led to the classification of these proteins into four groups including purple acid phosphatases (PAPs). Specific primers were degenerated and designed based on conserved sequences of PAPs isol...

The activities of acid phosphatase and alkaline phosphatase were investigated in two varieties of ripening Carica papaya fruit; Oblong-shaped variety which is also known as ‘Agric pawpaw’ and Pear-shaped variety which is also known as ‘Local pawpaw’. Acid phosphatase activity decreased significantly (p < 0.01) throughout the ripening stages from 0.0186±0.0006 to 0.0037 ± 0.0002μmol/min/g fresh ...
