Anti-TSH alpha antibodies are protein reagents that detect specific antigens. The TSH alpha antigen is another term for the human protein glycoprotein hormones, alpha polypeptide, encoded by the CGA gene. The protein is known to function in GPCR signaling pathways and the regulation of cell migration, among other biological roles. Canonically, it has an amino acid length of 116 residues and a mass of 13.1 kilodaltons. It is a secreted protein and it is expressed in the pituitary gland and placenta. The TSH alpha protein is a member of the Glycoprotein hormones subunit alpha protein family. Other alias names for TSH alpha include CG-ALPHA, FSHA, and GPA1. ELISA is the most common application for the TSH alpha antibodies listed below. Western Blot and Immunohistochemistry are also common applications.
