| Igs | immunoglobulins |
| kappa | a light chain of human immunoglobulins [chain] |
| SmIg | Surface membrane immunoglobulins |

| TSI | Thyroid Stimulating Immunoglobulins |
| TBII | Thyrotrophin binding inhibiting immunoglobulins |
| immunoglobulins, light-chain | Polypeptide chains, consisting of 211 to 217 amino acid residues, isolated from immunoglobulins and having a molecular weight of approximately 22 kD. There are two major types of light chains, kappa and lambda. In man they are found in a ratio of 60% to 40%, respectively. Both chains consist of linear repeating, similar, but not identical, segments of about 110 amino acid residues. In each segment a disulfide bond establishes a tightly folded approximately 60-membered loop or domain. Adjacent domains are linked by less tightly folded regions. Both light chains contain two such domains. Two light and two heavy chains make one immunoglobulin molecule, but both light chains in one ig are of the same type. (12 Dec 1998) |

| immunoglobulins, mu-chain | Heavy chains found in the fab and fc fragments of IgM and having a molecular weight of approximately 72 kD. They contain about 57 amino acid residues arranged in five domains and have more oligosaccharide branches and a higher carbohydrate content than the heavy chains of IgG. (12 Dec 1998) |
| immunoglobulins, surface | Immunoglobulins bound to the surface of lymphocytes. (12 Dec 1998) |
| immunoglobulins, thyroid-stimulating | Autoantibodies that bind to the thyroid-stimulating hormone (tsh) receptor (receptors, thyrotropin) on thyroid epithelial cells. The autoantibodies mimic tsh causing an unregulated production of thyroid hormones characteristic of graves' disease. (12 Dec 1998) |
| thyroid-stimulating immunoglobulins | In Graves' disease, the antibodies to TSH receptors in the thyroid gland. These antibodies are produced by B-lymphocytes and stimulate the receptors, causing hyperthyroidism. Formerly known as LATS (long-acting thyroid stimulator). (05 Mar 2000) |
