Acid phosphatase (E.C.3.1.3.2) in a giant cell bone tumor and a spleen infiltrated with hairy cells was extracted by citrate buffer and then by 0.3 mol/L NaCl. The cationic acid phosphatase in the crude extract was isolated by CM-cellulose chromatography, and further separated by high pressure
Alkaline phosphatase (AP) activities of sera from guinea fowl infected with osteopetrosis virus strain PTS-56 were investigated. Enzyme activities in birds of infected and control groups varied. AP activities in control guinea fowls, 10 to 15 weeks of age, were twice as high as those of 1-year-old
Cultured rat osteosarcoma (UMR106) alkaline phosphatase was purified to apparent homogeneity by sequential application of polyclonal antibody affinity, DEAE-cellulose, and Sepharose CL-6B chromatography. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the enzyme preparation treated with
Using routinely processed, paraffin-embedded tissue specimens, osteoclast-like giant cells in giant cell tumour of bone (GCT), chondroblastoma, osteoblastoma and osteoblastic osteosarcoma were examined histochemically for osteoclast-specific enzymes tartrate-resistant acid phosphatase (TRAP) and
Bone tumors, which consist largely of fibroblast-like cells, were categorized into ALPase-positive (3 ossifying fibromas and 2 fibroblastic osteosarcomas) and negative (4 non-ossifying fibromas and 5 MFHs) groups. They were investigated as to their ultrastructure and immunophenotype using antibodies
Polyacrylamide gel electrophoresis utilizing sodium dodecyl sulfate followed by specific staining for alkaline phosphatase was accomplished using sera from patients with osteosarcoma, polyostotic fibrous dysplasia, metastatic bone tumor, and idiopathic hyper-alkalinephosphatasemia. Alkaline
