Ab(MT) was con.jugated to poly-N-isopropylacrylamide (p-NIPAAm) to form Ab(MT) bound thermally reversible hydrogel p-NIPAAm-Ab((MT) A competitive immunoassay method based on the competition of fluorescein isothiocyanate (FITC) labeled MT antigen (FITC-Ag(MT)) and free MT with limited amount of p-NIPAAm-Ab(MT) was established. The separation in the assay process was achieved by precipitation of the immuno-complex above its critical solution temperature. The detection limit for MT is 50ng/ml. The recoveries of MT from human serum are satisfactory.展开更多
