Abstract
The present disclosure relates to a liquid handling device, methods of operating a liquid handling device, a method of performing a diagnostic test, a computer program and a system. In particular, the liquid handling device is capable of controllable bi-directional or multi-directional flow of reagents across one or more reaction zones allowing rapid, precise and controllable quenching of reactions and/or biological interactions.
Claims7
A method of performing a diagnostic assay comprising sequentially moving a sample liquid from a sample chamber to a measurement chamber and moving a first liquid reagent into the measurement chamber from an alternate flow direction, the method including:
- filling the sample chamber with the sample liquid;
- moving the sample liquid from the sample chamber to the measurement chamber;
- retaining the sample liquid in the measurement chamber for a predetermined period of time;
- moving the first liquid reagent from a first liquid reagent chamber into the measurement chamber in an alternate flow direction to the sample chamber liquid;
- and
- taking a measurement, optionally wherein the first liquid reagent is retained in the measurement chamber for a predetermined period of time,
- wherein the first liquid reagent is removed from the measurement chamber before the measurement is taken.
A method of performing a diagnostic assay comprising sequentially moving a sample liquid from a sample chamber to a measurement chamber and moving a first and second liquid reagent into the measurement chamber from an alternate flow direction, the method including:
- filling the sample chamber with the sample liquid;
- moving the sample liquid from the sample chamber to the measurement chamber;
- retaining the sample liquid in the measurement chamber for a predetermined period of time;
- moving the first liquid reagent from a first liquid reagent chamber into the measurement chamber in an alternate flow direction to the sample liquid;
- moving the second liquid reagent from a second liquid reagent chamber into the measurement chamber in an alternate flow direction to the sample liquid and performing a measurement, optionally wherein the first and second liquid reagents are each retained in the measurement chamber for a predetermined period of time, wherein the second liquid reagent is removed from the measurement chamber before the measurement is taken.
