Description:
A sensitive and specific radioimmunoassay for the insulin receptor has been developed employing receptor autoantibodies from the serum of a patient with insulin-resistant diabetes. The assay detects insulin binding sites at concentrations as low as 0.1 nanomolar; distinguishes between receptors originating from human placental membranes, human lymphoblastoid cells, and mouse liver membranes; and measures the receptor independently of its binding function. Down-regulation, or loss of binding after exposure to insulin, is associated with loss of immunoreactive receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harrison, L C -- Flier, J -- Itin, A -- Kahn, C R -- Roth, J -- New York, N.Y. -- Science. 1979 Feb 9;203(4380):544-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/83675" target="_blank"〉PubMed〈/a〉
