Abstract
The method described coats the interior of a tube-like support with the binding partner of the analyte. Analyte and anti-analyte-label conjugate are added. When the tube-like support is rotated end-over-end, the thin layer of analyte and conjugate readily react with the binding partners to form an immobilized label complex. When rotation stops, the reaction quenches to provide precise timing. The label complex is released and measured.
