摘要

We have developed a two-site immunoassay for human prolactin using two monoclonal antibodies: one of them immobilized on the solid phase and the other labelled with biotin. The serum is incubated simultaneously with the antibody-coated bead, the biotinylated antibody and the tracer (streptavidin-isoluminol or avidin-peroxidase complex). Our experimental work has been directed towards a common set of reagents to capture the prolactin and then, with different tracers, towards obtaining on the calibration curve the same results for unknown samples. On the basis of the positive results we obtained, we have developed a kit that can be used by the customer or as an enzyme-immunoassay or as a chemiluminescent immunoassay, depending on instrumentation available, spectrophotometer or luminometer.
