ABSTRACT:
Immunochemical composites consisting of saturating amounts of radio-labelled triiodothyronine (T.sub.3) or thyroxine (T.sub.4) complexed respectively to anti-T.sub.3 or anti-T.sub.4 antisera covalently coupled to suspendable porous glass particles via an intermediate silane coupling agent. The composites are pre-loaded into individual tubes used in solid phase radioimmunoassay of T.sub.3 or T.sub.4, requiring the addition of only test serum or standard, thereby minimizing chances of erroneous assay.
