Methods and apparatuses for performing immunoassays

摘要

Methods and apparatuses are featured for preconcentrating immunological reactants prior to their contact and reaction to enhance the rate of reaction for separating reacted and unreacted reactants and, also, to increase the sensitivity at the detector-measuring system. The preconcentration of the reactants finds particular use in immunoassays, where very often an immunospecies is very dilute causing a time consuming and/or insensitive assay. The preconcentration and separation are accomplished within the reaction medium resulting in a simplified and compact apparatus.
