duction in neutrophils is induced by G-CSF, and NAP is released into the bloodstream, perhaps through leakage of ALP from damaged or dead neutrophils. Fossa et al. (9 ) reported leukocytosis and increased serum ALP in response to G-CSF treatment and suggested that increased serum ALP activity was related to release of the enzyme from the increased numbers of leukocytes. Neutrophils were reporte...

To separate liver and bone alkaline phosphatase (ALP) isoenzymes in human serum, we used high-performance affinity chromatography (HPAC) on a column of wheat-germ lectin conjugated to 7-microns-diameter silica particles and an eluent containing N-acetyl-D-glucosamine (NAG). On-line spectrophotometric detection of ALP involved pumping diethanolamine-buffered p-nitrophenyl phosphate solution post...

Diagnosis Serum alkaline phosphatase (ALP) measurement: Measurement of serum ALP activity has been used as a screening test for HAC. However, the best way to use measurement of ALP activity may be as a means to rule out the diagnosis of HAC. The sensitivity of this laboratory test is high, as ALP is above normal in 90% of dogs with HAC. 2 However, the specificity is very low. Scottish terriers ...

The ALP (alkyl-lysophospholipid) edelfosine (1-O-octadecyl-2-O-methyl-rac-glycero-3-phosphocholine) induces apoptosis in S49 mouse lymphoma cells. A variant cell line, S49AR, made resistant to ALP, was found previously to be impaired in ALP uptake via lipid-raft-mediated endocytosis. In the present paper, we report that these cells display cross-resistance to Fas/CD95 ligation [FasL (Fas ligand...

Objective: Alkaline phosphatase (ALP) is considered a biomarker of high bone turnover in hemodialysis (HD) patients with secondary hyperparathyroidism. This study was conducted to determine whether high serum ALP levels are associated with increased all-cause mortality of HD patients. Patients and Methods: This was a retrospective cohort study conducted at a single center. The subjects were 195...

The performance characteristics of two bone alkaline phosphatase (ALP; EC 3.1.3.1) assays, a wheat germ agglutinin (WGA) precipitation assay and a new immunoadsorption assay (IAA), were compared. The withinand between-run imprecision of the IAA (3.6-4.2% and 3.6-7.7%) was comparable with that of the WGA assay. The mean crossreactivity with liver ALP appeared to be 4% in the WGA assay and 11 % i...

Low-density polyethylene (LDPE) films cografted with vinylene carbonate (VCA) and Nvinyl-N-methylacetamide (VIMA) were studied as a matrix for the immobilization of the enzyme alkaline phosphatase (ALP) either by direct fixation or by inserting spacers. When water-soluble alkyldiamines such as diaminoethylene, diaminobutane, diethylenetriamine, and diaminohexane were used as spacers between the...
