Serine peptidase inhibitor Kazal type 5 (SPINK5), also known Lympho-epithelial Kazal-type inhibitor (LEKTI) which is highly expressed in the thymus and stratum corneum, protects mucous epithelia against microbial attack and inflammation. SPINK5 is found in the oral mucosa, parathyroid gland, Bartholin's glands, tonsils, and vaginal epithelium. Very low levels are detected in lung, kidney, and prostate. SPINK5 is a marker of epithelial differentiation and expresses strongly in the granular and uppermost spinous layers of the epidermis and differentiated layers of stratified epithelia. Defects in SPINK5 are the cause of Netherton syndrome (NETH), a severe autosomal recessive disorder characterized by atopic dermatitis, hayfever and other conditions. (Shipping Cost: €200.00)

Thyroglobulin [SPM517]

Thyroglobulin (TG) is a dimeric glycoprotein specific to the thyroid gland which belongs to the type-B carboxylesterase/lipase family. It is the precursor of the iodinated thyroid hormones triiodothyronine (T3) and thyroxine (T4). Variations in TG are associated with susceptibility to autoimmune thyroid disease type 3, and defective or impaired TG synthesis usually results in congenital goitrous hypothyroidism, virtual absence of TG in thyroid tissue, and the presence of an elevated concentration of iodoalbumin. The final result of these abnormalities is a decreased rate of T3 and T4 synthesis. Thyroglobulin is found in normal thyroid and differentiated thyroid carcinoma cells but not undifferentiated thyroid. Thyroglobulin is a useful marker for identification of tumors with thyroid origin.
