Radioimmunoassay of serum ferritin.
Purified human spleen ferritin was labelled with 125I. On Sepharose 6-B gel filtration four species of labelled products were separated: a component with a higher molecular weight than ferritin; a component which is eluted in the same volume as unlabelled ferritin; and two labelled compounds with molecular weights lower than ferritin. When these labelled materials were used in a double antibody...
متن کاملImplications of using different tissue ferritins as antigens for ferritin in serum: four radioimmunoassay kits compared.
We compared three serum ferritin radioimmunoassay kits and one noncommercial RIA for ferritin quantitation, with regression analysis of results for sera from 35 ostensibly healthy subjects. There was a good correlation (p less than 0.001) between these various RIAs, but the slope of the regression line varied widely, most probably because of lack of standardization of the serum ferritin assay. ...
متن کاملRadioimmunoassay of serum estrogen.
Radioimmunoassay of serum estrogen (sum of estrone and estradiol-17f3) in 0.5 ml of human serum is described. After dilution of the serum, the estrogens are adsorbed on a Sephadex G-15 column in the presence of dilute HC1 and then eluted with benzene. After evaporation of the benzene eluate, the estrogens are dissolved in bovine serum albumin (5 g/. liter solution, at pH 8.0). An aliquot of thi...
متن کاملPositive interference in Radioimmunoassay determination of serum total T3
Introduction: Determination of thyrotropin, total and free thyroxine and triiodothyronine are widely used as diagnostic methods for thyroid function evaluation. There have been numerous reports of interferences in thyroid hormone immunoassays. Herein, a prominent positive interference is reported for a radioimmunoassay kit of total triiodothyronine. Materials and Methods: In this study, a total...
