Symptoms of Hashimoto's Thyroiditis: Introduction. The types and severity of symptoms of Hashimoto's disease vary between individuals. Many people have no symptoms at all. If Hasimoto's disease leads to hypothyroidism, symptoms of an underactive thyroid may develop. At the onset of hypothyroidism, symptoms can be vague and develop slowly. They may not include weakness, weight gain, cold sensitivity, cold hands and feet, fatigue, dry skin, brittle nails, and thinning, brittle hair.
Ligand Binding Assays (LBA) is an assay, or an analytic procedure, whose procedure or method relies on the binding of ligand molecules to receptors, antibodies or other macromolecules.on specific binding refers to the binding of a ligand to something other than its designated receptor such as various other receptors, or different types of transporters in the cell membrane. For example, various antagonists can bind to multiple types receptors.
1 Not all cells have a hormoneâs compatible receptor. The ones that do are called target cells.  Once inside a target cell, the hormone (pink) binds to a receptor (purple) - similar to a hand sliding in a glove or mitten - and forms what is known as a hormone-receptor complex between the ligand and receptor. A ligand is any molecule that binds to a specific site on a protein or other molecule.
