A cartridge includes a male end, a female end and an internal chamber defined by a filter adjacent the male and female ends. The cartridge is specifically designed to be stackable with additional cartridges, as the male end of one cartridge can close the female end of a different cartridge. The cartridges are useful in holding samples for analysis.

Cartridge assembly

The presence of an antigenic analyte ligand in a liquid sample is determined by (1) mixing the sample with a fluorescently labeled ligand immunologically complexed onto a solid phase supported antibody capable of exchanging the fluorescently labeled ligand with the analyte ligand in the sample and (2) measuring the fluorescence of the resulting liquid phase without measuring the fluorescence of the resulting solid phase and without separating the resulting solid phase from the resulting liquid phase.

Integrated solid-phase immunoassay

A cartridge assembly useful as a sampling or test device includes a cartridge and a closure tubing adapted to close either or both ends of the cartridge and to serve as a conduit for liquids eluted from the cartridge.
