<p>ASSAYAn assay apparatus, assay method, assay card and an assay card controller aredisclosed. The assay apparatus comprises: an assay card comprising a substrate having aplurality of compressible reagent reservoirs thereon, each of the plurality of compressiblereagent reservoirs containing an associated reagent and each of the plurality of compressiblereagent reservoirs being coupled with a reaction chamber operable to receive a test sample;and an assay card controller comprising a compression mechanism operable to compress eachof the plurality of compressible reagent reservoirs to cause each associated reagent to beinjected in a predetermined order into the reaction chamber to react with the test sample. Suchan arrangement provides a sequential compression of the reagent reservoirs to enablesequential injection of reagent liquids into the reaction chamber in a pre-programmed mannerusing a very simple and reliable squeezing mechanism. This simple arrangement enablescomplex reagent reactions to occur which can be carefully controlled using a simple, low costand reliable device which is easy to operate with a low level of skill and provides a sensitiveand reproducible assay.Figure 2</p> |
