The Ultrastructure of Human Thyroglobulin
Thyroglobulin molecules purified in a single step procedure by gel filtration were studied in the electron microscope using the negative staining technique. The molecule had the shape of a flexible helix with two turns. Its length was about 220 A and the maximal diameter of the coiled part of the molecule was estimated to be 110 A. The pitch varied between 40 and 50 A. Thyroglobulin molecules d...
متن کاملCharacterization of a hormonogenic domain from human thyroglobulin.
A polypeptide domain of molecular mass near 22 kDa was purified from CNBr-digest of iodine poor human thyroglobulin (hTgb). This fragment represents the N-terminal part of the hTgb molecule and consequently contains the preferential hormonogenic tyrosine 'acceptor' of the protein. This fragment could correspond to the non-iodinated and unreduced form of the thyroxinyl-containing 26 kDa peptide ...

متن کاملProduction of anti-human thyroglobulin and anti-thyroid hormone antibodies in rabbits immunized with human thyroglobulin.
Two rabbits (TG-1, TG-2) were immunized with human thyroglobulin (HTg) and bled serially. Antisera were obtained at different times after the first immunization and kept separately and studied. In both rabbits production of anti-HTg, and anti-thyroid hormone antibodies such as anti-thyroxine (T4) and anti-triiodothyronine (T3) antibodies was observed. Binding parameters of anti-HTg antibodies w...
متن کاملPrimary mediastinal goiters
BACKGROUND Primary mediastinal goiters (PMG) are very uncommon; few cases were reported in the literature. PATIENT DESCRIPTION We report here two cases of mediastinal goiters that met all criteria of PMG. Transternal approach was necessary for complete removal and pathological diagnoses confirmed their adenomatous goiter nature. The rarity of their occurrence, their clinical characteristics a...
