Thyroglobulin Antibody[P1054]

甲状腺球蛋白 thyroglobulin

脊椎动物甲状腺中大量存在的特异的含碘蛋白质。作为甲状腺激素的甲状腺素3， 5， 3′ -三碘甲腺原氨酸，是甲状腺内这种蛋白的酪氨酸残基经碘化所生成的碘化酪氨酸的两个残基，进一步缩合而生成的。这类激素需经蛋白酶作用于甲状腺球蛋白，使其变成游离态释放于血液中。由此可见，甲状腺球蛋白是甲状腺激素生成的场所，另也起着贮存型分子的作用。分子量约为 67万，等电点为 pH4.5左右。由于种属的不同，具有含碘量不相同的各种分子，其含量为 0.2-1%。除上述两种甲状腺激素含碘氨基酸残基外，还有二碘

Methods of Measuring Thyroglobulin and Peptide-Methylcoumarinamide Hydrolysis by Autoantibodies

Polyclonal antibodies often serve as the starting point for interesting studies of new antibody functions and their links with immunoregulation and autoimmune disease. For example, the catalytic activity of naturally formed antibodies
