FAST 6000 - Rapid, Portable, Fluorometric Assay System

The Flow Assay and Sensing System (FAST) is a second-generation instrument, developed under contract to the Naval Research Laboratory (NRL) as a rapid, portable system for performing flow immunoassays with detection limits to 1 part per billion. The FAST 6000 can be configured either as a single channel, single analyte instrument or as a six channel, six analyte instrument, capable of performing six simultaneous assays for six different analytes on the same sample. The system is completely self-contained, needing only a bottle of buffer and a waste bottle for field operation.

In operation, this small-molecule assay system uses a fluorophore-labeled analyte, bound to analyte-specific antibody that is immobilized on a permeable membrane. When a sample containing analyte passes through the membrane an exchange reaction occurs, displacing the labeled analyte which is measured downstream. A typical assay requires two minutes to run and up to fifty assays can be performed before the instrument must be recharged.
