Abstract:
An apparatus for assaying one or more lateral flow test devices. The apparatus comprises at least one support device for supporting one or more lateral flow test devices in use and at least one sample receptacle configured to receive, in use, a respective liquid sample to be dispensed onto a corresponding lateral flow test device. The apparatus further comprises a dispensing apparatus configured to dispense a known volume of the received liquid sample from the sample receptacle onto the corresponding lateral flow test device supported by the support device.
Abstract:
There is provided a pipette tip disposal assembly. The assembly comprises a receiving element adapted to support an end of at least one pipette tip, the at least one pipette tip being toppled in use from the receiving element along a first direction; and a container positioned to receive the at least one toppled pipette tip, the at least one pipette tip falling towards a base of the container on being received by the container. The base of the container has a first linear dimension aligned with the first direction corresponding to the length of a pipette tip.
Abstract:
A substrate comprising a coating of a masking material, and a plurality of discrete reaction zones onto which one or more binding agents are intended to be attached, wherein said zones are uncoated areas on the substrate.
Abstract:
The present invention describes methods for screening for cancer in a subject, by measuring the level of dimeric IL-18 in a sample obtained from the subject, and comparing that level with the level in a normal control sample.The present invention also describes an assay for screening for cancer in a subject, by measuring the level of dimeric IL-18 in a sample obtained from the subject, whereby an elevated level of dimeric IL-18 is indicative of cancer.

Abstract:
There is provided an assay fluid delivery system comprising an array of fluid reservoirs (62), each of which is selectively actuatable to deliver a respective fluid to a fluid channel structure; and a fluid delivery control system (50) comprising a plurality of reciprocally mounted actuators, each associated with a respective reservoir and being movable between a retracted position and an actuating position at which it causes fluid to be delivered from the corresponding reservoir, a plurality of cams (22) with different profiles mounted on a common, rotatable cam shaft (6), each cam being engaged with a respective one of the actuators whereby rotation of the cams causes movement of the corresponding actuators between the retracted and actuating positions, and a motor coupled to the cam shaft for rotating the cam shaft, wherein the cams are shaped relative to one another so as to cause the corresponding actuators to actuate the reservoirs in a predetermined sequence and for predetermined respective times.
Abstract:
The present invention provides biomarker-based methods for diagnosing stroke in a patient suspected of having suffered a stroke, and also for discriminating between ischemic stroke and transient ischemic attack. Substrates comprising probes for specific combinations of biomarkers useful in the methods of the invention are also described.
Abstract:
A capacitive liquid level sensor is provided comprising a capacitive probe having a capacitance and comprising a sensing tip wherein the capacitive probe is configured such that the capacitance of the probe changes when the sensing tip is exposed to liquid. A signal generator operates to supply an electrical signal alternating between a high and low state to the capacitive probe, the electrical signal being configured such that the probe is alternately charged and discharged when the signal is high or low respectively. A comparator operates to detect the magnitude of an electrical signal across the capacitive probe and provides a first output signal value when the detected signal magnitude is greater than a predetermined threshold value and a second output signal value when the signal magnitude is less than the threshold value. A timer operates to receive an output signal from the comparator and measures a time period starting when the comparator output signal transitions to the first output signal value and ending when the comparator output signal transitions to the second output signal value. Liquid detection means also operate to utilise the time period measured by the timer to determine if the sensing tip is exposed to liquid.
