Use of polyethylene glycol in radioimmunoassay of human placental lactogen.
نویسندگان
چکیده
We describe a rapid radioimmunoassay for human placental lactogen in biological fluids, with use of polyethylene glycol to separate free from antibody-bound placental lactogen. The standard curve obtained, easily fitted to a logit-log transformation, is useful over a concentration range of 6 to 400 ug/liter. Within-assay variability is 1.97%, between-assay variability 2.20%. The relation is linear when lactogen added is plotted against that accounted for analytically, the actual recovery being 100.26%.

Discrete modular system for automation of radioimmunoassay of serum choriomammotropin.
We describe a discrete automated radioimmunoassay system for determining choriomammotropin (placental lactogen) in human serum. With the present system it can be measured in as many as 37 unknown sera (50 muL) and three quality-control sera, in duplicate, within 1.5 h. The time required for sample preparation, incubation (15 min), and separation of free and bound radioactivities (a 150 mL/L pol...
متن کاملColumn affinity chromatography for bound/free separation in ligand assays. I. Radioimmunoassay of choriomammotropin (human placental lactogen).
A method is described for separating antibody-bound from free fractions in ligand assays by column affinity chromatography, and its application to radioimmunoassay of choriomammotropin. In the method, 70 x 10 mm (i.d.) polypropylene columns containing about 150 mg of immunosorbent (goat anti-rabbit gamma-globulins covalently linked to Sepharose CL-4B) are used. Standards or unknowns, tracer and...
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 کاملPlacental lactogen levels as guide to outcome of threatened abortion.
The clinical value has been assessed of circulating placental lactogen levels as a pointer to the outcome in a patient with vaginal bleeding in early pregnancy. By using a semiautomated radioimmunoassay the normal range of values for the first and second trimesters has been established. In patients admitted with vaginal bleeding after the eighth week of gestation estimation of plasma human plac...
متن کاملMulticomponent radioimmunoassay: simultaneous measurement of choriomammotropin and pregnancy-specific beta1-glycoprotein in pregnancy serum.
We describe a receptacle for use in the simultaneous radioimmunoassay of two serum constituents in a single sample, and the application of this principle for the measurement of human pregnancy serum choriomammotropin and pregnancy-specific beta 1-glycoprotein. The analytical performance of this multicomponent radioimmunoassay approaches that of conventional radioimmunoassays. By following the p...
