Scientific Data Images for Human Serpin A7/TBG Antibody

Detection of Human Serpin A7/TBG antibody by Western Blot.

Detection of Human Serpin A7/TBG by Western Blot.

Western blot shows human plasma. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human Serpin A7/TBG Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8176) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Serpin A7/TBG at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Serpin A7/TBG

Serpin A7 (also TBG/Thyroxine-binding globulin and T4-binding globulin) is a secreted 54 kDa glycoprotein, non-inhibitory member of the serpin family of proteins. It is expressed by the liver and secreted in plasma. Mutations in the SERPINA7 gene can result in a whole spectrum of deficiencies, characterized by either reduced or increased TBG levels in the serum. A deficiency in TBG result in low serum total T4 and T3 count in clinically euthyroid subjects in the presence of normal serum TSH. Over aa21-415, human serpin A7 shares 76% aa sequence identity with mouse serpin A7.
