标题:Effect of Spacer Groups Connecting Insulin with Fluorophore in Gly(A1)-sulfobenzoxadiazole-Labeled Insulins on the Immunoreactivity toward Anti-insulin Antibody
摘要:The immunoreactivity (specific binding) of three Gly(A1)-sulfobenzoxadiazole-labeled insulins which have different spacer groups, Gly(A1)-[3-(4-sulfobenzoxadiazol-7-ylthio)propanoyl]-insulin, Gly(A1)-[2-(4-sulfobenzoxadiazol-7-ylthio)acetyl]-insulin, Gly(A1)-[3-carboxy-2(or 3)-(4-sulfobenzoxadiazol-7-ylthio)propanoyl]-insulin, toward an antiporcine insulin monoclonal antibody was investigated, where solid-phase fluoroimmunoassay technique was utilized. The immunoreactivities of three labeled insulins were 2.1, 1.8 and 1 in that order.
