Thyroglobulin Antibody Staining Protocol for Immunohistochemistry

 

Description: Antibody to thyroglobulin has been shown to be useful in positive identification of thyroid carcinomas of the papillary and follicular types. Demonstration of thyroglobulin in a metastatic lesion establishes the thyroid origin of the tumor. Adenocarcinomas of non-thyroidal origin are not reactive.

Additional Information:

Species Reactivity: Human, mouse, rat

Fixation: Formalin fixed paraffin sections

Positive Control: Thyroid, colon
