A tine-resolved immunofluorometric assay for human serum B_2-mi-crogloblin / 中国免疫学杂志

In the article, we report to introduce biotin-avidin system (BAS) into time-resolved im-munoflurometric assay (TRIFMA) and first with success established human serum ?_2-mG solidphase sandwich BAS-TRIFMA. The mean intra and inter C. Vs are 8. 0% and 11.7% respectively. The detection sensitivityis 0.6ug/ml. The average recovery is 101.2%. 42 serum samples are measured with TRIFMAand RIA,the results are giving satisfactory correlation coefficient of 0.9614,P
