摘要 |
The present invention provides methods of detecting analytes using particles having different physico-chemical properties, such as buoyancy, size, density, spectral characteristics, and/or binding properties, in solution-based sandwich assays and solution-based competition assays. The methods can be performed using rotors and bench-top centrifuges and provide for rapid, qualitative and quantitative detection of analytes. The present invention also provides kits that can be used to perform the methods, and mixtures containing particles suitable for the methods.
