Abstract
Disclosed and claimed are methods and apparatus for performing a binding assay for an analyte of interest present in a sample based upon measurement of electrochemiluminescence at an electrode. The method uses magnetically responsive particles. The method and apparatus call for a plurality of electromagnets or permanent magnets in north-south orientation for imposing a magnetic field so as to collect the particles.
