Development of a plasma 17α-hydroxyprogesterone time resolved-fluorescence immunoassay involving a new biotinylated tracer
摘要:
A biotinylated 17 alpha-hydroxyprogesterone probe (3) was prepared from 17 alpha-hydroxyprogesterone-3-carboxymethyloxime and conjugate obtained by acylation of biotinylaminopropylammonium trifluroacetate. This new tracer was used in the development of a 17 alpha-hydroxyprogesterone time-resolved fluoroimmunoassay using streptavidin-europium. The new method was compared to a long-standing radioimmunoassay method and found to be more sensitive and economical. (C) 2000 Elsevier Science Inc. All rights reserved.
