Biological analysis method for antibody against thyroid stimulating hormone receptor, measurement kit for antibody, and genetically modified cell modified for use in the biological analysis method or in the measurement kit

摘要

The present invention provides a method and a kit for assaying a TSH receptor antibody, which are easy to manipulate and are safe. Specifically, the present invention provides a composition comprising a genetically modified cell forced to co-express a TSH receptor, a cyclic nucleotide responsive calcium channel, and a luminescent protein aequorin. Use of the composition enables the assay of a TSH receptor antibody contained in a sample.
