    摘要: An immunoassay method involves the use of one or preferably two enzyme amplification steps to increase assay speed or sensitivity. In a first step, a first enzyme is generated in an amount related to the concentration of an analyte in a sample. In a second step, the first enzyme acts on a first substrate to reveal antigenic determinants of a first product. In a third step, the first product is reacted with an antibody. The extent of this immune reaction is determined, preferably by means of an enzyme signal system. Two assays for digoxin and one for 17α-­hydroxyprogesterone all using beta-galactosidase as the first enzyme are described.
