Method and apparatus for enabling resuspension wash and magnetic localization of sample components bound to particles with magnetic properties in reaction vessels during separation and wash for enhanced chemiluminescent signal generation in biomedical assays. The assays involve moving reaction vessels past magnetic arrays that partially localized the particles prior to passing a gap where washing occurs, with or without resuspension after, separating out the unbound particles and liquid. The band of particles is further localized by a focusing magnet at the end of the array prior to dosing the vessel with acid for chemiluminescent purposes. A block of soft magnetic material is employed in …

Why it's free to use
- Filed March 5, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 5, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 5, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
