Rapid method for the quantitative determination of serum alkaline phosphatase.
S ERUM ALKALINE PHOSPHATASE ACTIVITY is the enzyme analysis most frequently made in clinical laboratories. It has long been a diagnostic tool and therapeutic index in both liver and osseous disease. Its usefulness could be expanded by a method which would measure alkaline phosphatase activity rapidly, accurately, and with a minimum of technical manipulation. Ideally, the substrate for such a me...
متن کاملInvestigation of enzymatic behavior of benzonase/alkaline phosphatase in the digestion of oligonucleotides and DNA by ESI-LC/MS.
We have developed an ion-pairing HPLC-MS method that has sufficient separation power, selectivity, and sensitivity to investigate the enzymatic behavior of benzonase/alkaline phosphatase upon digestion of oligonucleotides and DNA. Mass spectrometry revealed that this enzyme pair can nonspecifically digest oligonucleotides and DNA into fragments ranging from 2 to 10 nucleotides, i.e., sizes suit...
متن کاملComparison of alkaline phosphatase-conjugated oligonucleotide DNA probe with the Sereny test for identification of Shigella strains.
We compared an alkaline phosphatase-conjugated oligonucleotide DNA probe with the Sereny test to determine the sensitivity and specificity of the probe in detecting virulent Shigella strains. The probe hybridized with all 52 Sereny-test-positive strains (sensitivity, 100%) and 4 of 21 Sereny-test-negative strains (specificity, 81%). The probe did not hybridize with any of the Sereny-test-negati...
متن کاملRapid and highly sensitive electrochemical determination of alkaline phosphatase using a composite tyrosinase biosensor.
The use of an amperometric graphite-Teflon composite tyrosinase biosensor for the rapid monitoring of alkaline phosphatase (ALP), with no need of an incubation step and using phenyl phosphate as the substrate, is reported. Phenol generated by the action of ALP is monitored at the tyrosinase composite electrode through the electrochemical reduction of the o-quinone produced to catechol, which pr...
متن کاملFluoride and Alkaline Phosphatase
Since serum alkaline phosphatase increases in fluoride therapy for osteoporosis, it is generally accepted that fluoride stimulates bone formation. However, histochemical studies have shown that alkaline phosphatase is also increased in resorbing osteocytes. Fluoride is toxic to metabolically active bone cells, alkaline phosphatase is released, and serum alkaline phosphatase increases. We propos...
