Polyclonal Rabbit Anti-Human
Thyroglobulin
Thyroglobulin is the precursor of thyroid hormones.
It is synthesized by thyrocytes and transported to the apical surface where it is secreted into the lumen of thyroid follicles and stored as the major component of colloid. The antibody is useful for the detection of thyroglobulin in thyroid tissue and is a useful tool for the identification of well-differentiated thyroid carcinomas.
Papillary thyroid carcinoma (FFPE) stained with FLEX Anti-Thyroglobulin, IR509/IS509.
Papillary thyroid carcinoma. The neoplastic cells show a strong cytoplasmic staining reaction.
Clinical application for IR509/IS509 For identification of tumors of thyroid origin such as thyroid follicular carcinoma, papillary thyroid carcinoma, Hürthle cell tumor of thyroid, and anaplastic carcinoma of thyroid.
Disclaimer: Due to variances among color computer monitors, the colors you see on your screen may not be the exact colors of the stain. The image you see should be considered close renditions to the actual stain.
- Optimized staining performance of both high- and low-expression structures
- Crisp and clear staining with no background
- Optimal laboratory efficiency with ready-to-use antibodies on Dako Autostainer Plus
FLEX Polyclonal Rabbit Anti-Human Thyroglobulin, Ready-to-Use (Dako Autostainer/Autostainer Plus), is intended for use in immunohistochemistry together with Dako Autostainer/Autostainer Plus instruments. This antibody is useful for the identification of thyroglobulin in thyroid tissue and is a useful tool for the identification of well differentiated thyroid carcinomas (1, 2). The clinical interpretation of any staining or its absence should be complemented by morphological studies using proper controls and should be evaluated within the context of the patient's clinical history and other diagnostic tests by a qualified pathologist.
In crossed immunoelectrophoresis using 12.5 µL concentrated antibody per cm2 gel area against 2 µL of human thyroid gland extract, only one precipitate corresponding to Tg appears. With 2 µL of human plasma, no precipitate appears. Staining: Coomassie Brilliant Blue.
In human thyroid cell cultures, the antibody labels intracellular Tg (4).
