Preparation and properties of thyroxine-binding alpha globulin (TBG).
Thyroxine-binding alpha globulin (TBG) in human serum was isolated from Cohn fractions IV-5,6 and IV-4 by (1) chromatography on carboxymethyl (CM) cellulose, (2) gel filtration on Sephadex G-200, (3) chromatography on diethylaminoethyl-Sephadex, (4) a novel procedure of "double-gel" electrophoresis, and (5) preparative polyacrylamide gel electrophoresis. The protein was homogeneous by analytica...
متن کاملStudies on human thyroxine-binding globulin (TBG). I. Purification of TBG and immunologic studies on the relationship between TBG from normal persons and those with TBG "deficiency".
A method for obtaining highly purified thyroxine-binding globulin (TBG) from whole human serum is presented. The method employs relatively simple procedures of step-wise ammonium sulfate precipitation followed by column chromatography on DEAE cellulose and DEAE Sephadex. The final product produces a single protein band on disc electrophoresis. The sedimentation constant of the TBG thus purified...
متن کاملThyroxine-protein interactions. Interaction of thyroxine and triiodothyronine with human thyroxine-binding globulin.
The effect of temperature on the binding of thyroxine and triiodothyronine to thyroxine-binding globulin has been studied by equilibrium dialysis. Inclusion of ovalbumin in the dialysis mixture stabilized thyroxine-binding globulin against losses in binding activity which had been found to occur during equilibrium dialysis. Ovalbumin by itself bound the thyroid hormones very weakly and its bind...
متن کاملThyroxine-Binding Globulin Concentrations
Plasma thyroid hormone concentrations may be abnormal in non-thyroid disease and pose diagnostic problems. For example, concentrations of triiodothyronine (T3) in the blood decline in acute illness with a reciprocal increase in reverse triiodothyronine (reverse T3), but thyroxine (T4) concentrations are usually normal or only slightly decreased (1, 2). However, McLarty et al. (3) reported that ...
متن کاملFamilial thyroxine-binding globulin deficiency.
Genetically determined thyroxine-binding globulin deficiency is described in two families in the United Kingdom. All subjects in both pedigrees were euthyroid. Transmission was by sex-linkage; males showed low serum protein bound iodine and high thyroxine (T4) resin uptake due to complete absence of serum thryroxine-binding globulin; females were less severely affected. The distinctive biochemi...
