title: Isoelectric focusing of the human TSH receptor A subunit.
abstract: The water soluble A subunit of the human TSH receptor has been shown to have an isoelectric point of 5. As both TSH and TSH receptor antibodies have isoelectric points in the region of 8-10, charge-charge interactions must be of major importance in the binding of hormone or antibody to the TSH receptor A subunit.
