摘要： The invention relates to a method of detection, a sensor and a test-kit which find application in immunological detection (e.g. immunoassay). The invention provides, inter alia, a method of dtection, suitable for use in immunological detection of an entity, which method includes the use of a secondary species (as defined in the Specification), the use of a first detectable species, and the use of a second detectable species. The method may include, for example, the use of a primary species, a secondary species, a first detectable species and a second detectable species. The primary species may be, for example, an antibody or a ligand. The secondary species may be, for example, an auxiliary species such as an auxiliary binder or an auxiliary ligand, or a species which has a part which is an auxiliary function. The entity to be detected may be an analyte species as such or may be an entity which carries or includes analytes species.

摘要： The invention relates to a separation method which finds application in immunological detection (e.g. in immunoassay and in immunosensors), to a method suitable for use in detection, to a sensor, to apparatus for use in detection, and to a test-kit. The invention provides, inter alia, a separation method, suitable for use in an immunological method for the detection of a plurality of entities, which method includes the use of a plurality of auxiliary ligand-binder pairs, the auxiliary ligand of each of the plurality of auxiliary ligand-binder pairs being provided on a support material. The invention also provides, inter alia, a separation method, suitable for use in an immunological method for the detection of a plurality of entities, which separation method includes the use of a plurality of auxiliary ligand-binder pairs, an auxiliary ligand of one auxiliary ligand-binder pair being provided on a support material and a binder of another auxiliary ligand-binder pair, which pair comprises an auxiliary ligand-auxiliary binder pair, being provided on a support material. In accordance with the invention multi-entity detection (e.g. multiple-analyte species detection) may be effected.
