Abstract:
The invention provides haptens, immunogens comprising such haptens coupled to an antigenicity-conferring carrier material, conjugates comprising such haptens bonded to a labelling agent as well as, antibodies raised against such immunogens and capable of binding with ketamine and its primary metabolite, norketamine.
Abstract:
An assay device incubator comprises a housing (46) defining a region within which at least one assay device is located in use, the housing defining laterally opposed sidewalls (48, 50) of at least one bay (33) in which an assay device can be located. The housing (46) includes one or more guides (49, 51) for supporting the assay device and enabling the assay device to undergo to and fro movement therealong. A vibration system (40, 60) is coupled to the at least one tray in use for vibrating the tray to and fro along the or each guide. A heating system (70) heats the region within the housing.
Abstract:
Novel haptens, which can be conjugated to form immunogens, are of formula I, II or III 1 wherein R is a divalent alkyl, cycloalkyl or aryl group having 1 to 10 carbon atoms, and X is a functional group.
Abstract:
A spin-trapping assay for nitric oxide, in a biological system such as whole blood, uses as the spin trap a lipid-soluble nitrobenzene compound such as 2,6-dimethylnitrosobenzene.
Abstract:
A biochip deposition system and method. The system comprises a deposit mechanism for depositing organic material in spots on a substrate; and a viewing system for detecting the spots on the substrate during a deposit operation and before the spots have dried, for determining if the spots have been correctly deposited, and if not, for generating a suitable output signal. The viewing system includes an illumination device for illuminating deposited spots at a relatively low angle relative to the substrate.
Abstract:
A method of manufacturing a diaphragm utilizing a precision grinding technique after etching a cavity in a wafer. A technique for preventing distortion of the diaphragm based on use of a sacrificial layer of porous silicon is disclosed.
Abstract:
An assay cartridge for use in a molecular diagnostics assay having an assay region; a first end comprising a first engagement member for engaging with a support housing; and a second end comprising a second engagement member for engaging with a support housing. The second engagement member has a clip, the clip being formed by a resilient element extending from the second end of the cartridge and a fastening element extending from said resilient element. The clip has a release element extending from the resilient element actuatable to release the clip from a caddy in use.
Abstract:
There is provided a sterilisation monitoring device for a molecular diagnostics analyser. The device comprises a sensor arranged in use to detect radiation; and an analysis unit connected to the sensor. The analysis unit is arranged in use to issue a signal when the radiation level incident on the sensor is lower than a threshold level.
Abstract:
A method of monitoring and controlling the processing of biological samples, the method comprising the steps of: receiving (101) a plurality of sample containers, each containing biological material; assigning (102) a priority to each of the sample containers; queueing (103) the sample containers for analysis based on the assigned priorities; extracting (104) a biological sample from each of the plurality of sample containers based on said sample container's position in the queue; analysing (105) each biological sample; providing (106) either a valid result or an inconclusive result for each of the biological samples based on said analysing; for each biological sample for which an inconclusive result has been provided, assigning (109) a new priority to the respective sample container and repeating the queueing, extracting, analysing, and providing steps.
Abstract:
Haematuria is a considerable burden within primary and secondary care; too many haematuria patients are referred to secondary care for invasive and expensive investigations that could be managed in primary care. The current invention has identified biomarker combinations with utility for the diagnosis of bladder cancer in males. Using gender specific biomarker algorithms in combination with clinical risks that are associated with bladder cancer, would allow clinicians to better manage haematuria patients in primary care setting.
