reads as follows:
40. A flow immunosensor for performing a real-time
analysis of a sample which is to be analyzed and which is not
yet present, said flow immunosensor consisting essentially of;
an exchanger including:
a chamber having an inlet port for sample
introduction and an outlet port,
a support medium, comprising a bed having a volume
of 0.1 to 0.5 ml, in the chamber,
an antibody immobilized on the medium wherein the
antibody recognizes with specificity and sensitivity a
target,
a labelled antigen complexed to said immobilized
antibody and capable of being displaced by the
target, said labelled antigen saturating the antigen-binding
sites of said antibody;
a detection apparatus connected to the exchanger via
