【Abstract】 Time-resolved fluoroimmunoassay (TrFIA) has been recognized as the most promisingone among the so-called nonisotopic immunoassays. It is well known for its inherentadvantages, high sensitivity, specifity and stability, rapid determination and widemeasurement range. We have developed a new TrFIA for determining microalbumin in urineby using monoclonal anti-HSA (human serum albumin) antibody and europium label. Thequality of the assay and its preliminary clinical application have been evaluated.更多还原
