Thyroglobulin Antibody (TGB24) - IHC-Prediluted Summary

• Description: The prediluted antibody does not require any mixing, dilution, reconstitution, or titration; the antibody is ready-to-use and optimized for staining.
• Immunogen: Human thyroid follicular cells
• Localization: Cytoplasmic, Secreted
• Marker: Thyroidal Cell Marker
• Specificity: Thyroglobulin is a 660kDa dimeric pre-protein with multiple glycosylation sites. It is produced by and processed within the thyroid gland to produce the hormone thyroxine and triiodothyronine. Prior to forming dimers, thyroglobulin monomers undergo conformational maturation in the endoplasmic reticulation. The vast majority of follicular carcinomas of the thyroid will give positive immunoreactivity for anti-thyroglobulin even though sometimes only focally. Poorly differentiated carcinomas of the thyroid are frequently anti-thyroglobulin negative. Adenocarcinomas of other-than-thyroid origin do not react with this antibody. This antibody is useful in identification of thyroid carcinoma of the papillary and follicular types. Presence of thyroglobulin in metastatic lesions establishes the thyroid origin of tumor. Anti-thyroglobulin, combined with anti-calcitonin, can identify medullary carcinomas of the thyroid. Furthermore, anti-thyroglobulin, combined with anti-TTF1, can be a reliable marker to differentiate between primary thyroid and lung neoplasms.

Applications/Dilutions

• Dilutions:
  • Immunohistochemistry
  • Immunohistochemistry-Paraffin
• Application Notes: Hu-chromosome location: 8q24.22 Molecular weight of antigen: 660kDa (Dimeric Form) Immunohistochemistry-Paraffin 0.5 - 1.0 ug/ml for 30 minutes at RT; Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10 - 20 min followed by cooling at RT for 20 minutes. The 7mL size is a pre-diluted size and no additional dilutions are required before using this item for the intended application.
• Theoretical MW: 660 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background

Thyroglobulin is synthesized by the follicular epithelial cells of the thyroid. Thyroglobulin is the glycoprotein precursor to the thyroid hormones. Its synthesis and metabolism have seemingly wasteful features. It has a molecular weight of 660,000, with 2 identical subunits of MW 300,000 and 10% sugars; yet its complete hydrolysis yields only 2 to 4 molecules of the iodothyroxines T4 and T3. Baas et al. (1986) showed that the TG gene encodes an 8.7-kb mRNA, covers at least 300 kb of genomic DNA and contains at least 37 exons separated by introns as large as 64 kb. A striking structural difference between the 5-prime and 3-prime parts of the gene suggested that it is composed of 2 evolutionarily different regions. The first 30 kb of DNA encodes 3 kb of the mRNA yielding an exon:intron ratio of 1:10, whereas the remaining 270 kb encodes 5.7 kb of the mRNA with a ratio of 1.47.
