A Radioimmunoassay for Placental-type Alkaline Phosphatase1
نویسندگان
چکیده
Rabbit antiserum was raised against preparations of placental alkaline phosphatase (AP) extracted from human term placentae. The antiserum precipitated AP from the placenta and from the intestine, but it was inactive against AP from bone and liver. The concentration of antiserum required to precipitate intestinal AP was about 10 times higher than that necessary to precipitate placental AP. Placental AP was labeled with iodide-1251 and was

Use of monoclonal antibodies to detect human placental alkaline phosphatase.
Convenient, sensitive, and specific solid-phase immunoassays involving monoclonal antibody are described for the determination of human placental alkaline phosphatase (hPLAP). An endogenous enzyme immunoassay combined the specificity of the immunological and the enzymatic reactions. Alternatively, a solid-phase "sandwich" radioimmunoassay involving immobilized polyclonal rabbit anti-hPLAP in co...
متن کاملIsolation, purification, and characterization of mouse placental lactogen.
Mouse placental lactogen was purified 1840-fold from BALB/c placentae from days 14-18 of gestation with an overall yield of 29%. The purification procedure included alkaline homogenization and extraction, ammonium sulfate precipitation, hydrophobic interaction chromatography on Phenyl-Sepharose, ion-exchange chromatography on CM- and DEAE-cellulose, and gel exclusion chromatography on Sephadex ...
متن کاملCharacterization of the placental alkaline phosphatase-like (Nagao) isozyme on the surface of A431 human epidermoid carcinoma cells.
A431 human epidermoid carcinoma cells monophenotypically express the placental alkaline phosphatase (PLAP)-like enzyme shown by its catalytic and antigenic characteristics, properties which are shared by the Nagao isozyme. More specifically, it is L-leucine sensitive just as is the rare placental D-variant of PLAP and the testicular heat-stable enzyme. Collectively, these are all referred to as...
متن کاملSerum placental type alkaline phosphatase in cigarette smokers.
By means of enzyme immunoassays based on two monoclonal antibodies with specificities for distinct forms of placental type alkaline phosphatase (Pl-ALP), together with L-leucine inhibition studies, it has been possible to distinguish the Nagao type carcinoplacental enzyme from other placental type alkaline phosphatases. This approach has shown that it is the Nagao type (placental like) enzyme w...
متن کاملStudies of the Regan alkaline phosphatase isoenzyme in plasma from a lung-carcinoma patient.
We compared an alkaline phosphatase (EC 3.1.3.1) isoenzyme from a plasma sample of a patient with carcinoma of the lung, who was suspected of having the Regan-type isoenzyme, with placental serum alkaline phosphatase and with tissue preparations from placenta, liver, bone, and intestine. The placental and Regan phosphatases responded similarly to heat treatment and modification by various inhib...
