Subunit heterogeneity of thyroglobulin.
The subunit structure of thyroglobulin has been investigated by gel filtration and polyacrylamide electrophoresis in sodium dodecyl sulfate (SDS) of the native and the S-carboxymethylated proteins. When the thyroglobulins from several species (calf, sheep, pig, man, rat, and guinea pig) were examined by polyacrylamide electrophoresis in SDS in the absence of reducing agents, most of the protein...
متن کاملSubunit heterogeneity in human serum beta lipoprotein.
The apoprotein of human serum beta lipoprotein has been prepared in a lipid-free and soluble form by a technique of interfacial extraction in the presence of guanidinium hydrochloride and nonionic amphiphile. Gel permeation chromatography of maleylated apobeta lipoprotein separates two protein fractions with different amino acid compositions. The smaller particle has a molecular weight of 2.6 x...
متن کاملHeterogeneity of the native ribosomal subunit fraction in HeLa cells.
Ribosomal particles, protein synthesis The cytoplasm of growing HeLa cells contains a certain quantity of native ribosomal subunits. They constitute a heterogeneous fraction consisting of at least two categories of particles. The first category comprises the newly emerging native 40S subunits whidi do not form 80S couples under any in vitro condition tried. It is postulated that these native su...
متن کاملThe Properties of Thyroglobulin VIII. THE IODINATION OF THYROGLOBULIN
It has been shown that when thyroglobulin is iodinated, a marked intensification occurs in its absorption spectrum in the region of 300 to 3fXl rnp in alkaline solution (1). It is also well known that the absorption peaks of iodinated tyrosine and thyronine derivatives occur in this spectral zone (2). A procedure based on these factors has been developed which permits the simultaneous determina...
متن کاملHETEROGENEITY OF MACROPHAGE POPULATIONS: ANTIBODIES DETECTING VARIOUS POPULATIONS OF MACROPHAGES
Two groups of antibodies against mouse resident alveolar and peritoneal macrophages have been raised individually in rabbits by immunization with whole cell suspensions of lavaged alveolar and peritoneal macrophages. The whole antisera reacted positively with neutrophils and lymphocytes. However, upon extensive absorptions with these cells the activity became restricted to macrophages. The...
