Autoantibody Profiles Of Myasthenia Gravis, Thymoma, and Lambert-Eaton Myasthenic Syndrome

Single Assay Detects AChR Modulating and AChR Blocking Antibody

May 2012

A single assay detects the acetylcholine receptor modulating and blocking antibody. Both lower the number of surface binding sites for radiolabeled alpha-bungarotoxin. Acetylcholine receptor modulating antibody accelerates endocytosis and degradation of the acetylcholine receptor. Acetylcholine receptor blocking antibody inhibits alpha-bungarotoxin binding to acetylcholine receptors.
