Abstract
The present invention provides an apparatus for retaining solid state reagents and/or for processing sample for a diagnostic test, where the apparatus avoids liquid “hang-up” that would otherwise result in loss of sample or fluid volume during sample transfer. The invention further provides diagnostic methods that employ the apparatus, so as to provide sensitive and accurate analyte detection.
Claims23
An apparatus retaining solid-state reagents, comprising a compartment containing the solid-state reagents in bead or pellet form, the compartment having an opening formed by a rib design sufficient to retain the solid-state reagents while reducing hang-up of liquid sample.
4-5. (canceled)
8-9. (canceled)
A method for detecting an analyte, comprising:
- applying a liquid sample suspected of containing the analyte to an apparatus retaining solid-state immunoreagents, the apparatus comprising a compartment containing the solid-state immunoreagents reagents in bead or pellet form, the compartment having an opening formed by a rib design sufficient to retain the solid-state reagents while reducing hang-up of liquid sample, thereby solubilizing the immunoreagents in the compartment;
- and
- delivering the liquid sample to a lateral flow membrane configured to interface with the apparatus.
