Specific Anti-Thyroxine Antisera Induced by Thyroxine Sensitized Liposomes

Abstract
Specific anti-thyroxine rabbit antisera were generated from complete Freund's adjuvant with liposomes consisting of sphingomyelin, cholesterol, dicetylphosphate and 5-N-thyroxine-2,4-dinitrophenyl-phosphatidylethanolamine (T4-Dnp-PE). Spin membrane immunoassay technique was used to measure the sensitivity and specificity of these antisera. Addition of 10 to 70 ng of Lthyroxine produced significant inhibition of immune lysis. Addition of L-3,3′ 5-triiodothyronine (T3) up to 800 ng showed no cross reaction.
