Abstract: Described herein is an analyte detection device and method related to a portable instrument suitable for point-of-care analyses. In some embodiments, a portable instrument may include a disposable cartridge, an optical detector, a sample collection device and/or sample reservoir, reagent delivery systems, fluid delivery systems, one or more channels, and/or waste reservoirs. Use of a portable instrument may reduce the hazard to an operator by reducing an operator's contact with a sample for analysis. The device is capable of obtaining diagnostic information using cellular- and/or particle-based analyses and may be used in conjunction with membrane- and/or particle-based analysis cartridges. Analytes, including proteins and cells and/or microbes may be detected using the membrane and/or particle based analysis system.

Abstract: A bag holder assembly is provided for suspending a storage bag and maintaining the orifice of the bag in the open position. The bag holder includes a base member, a plurality of bag support members, and a bag attachment means. The base member is preferably comprised of multiple beams joined together by a connecting means. The bag support members attach to and extend from the base member. Each bag support member comprises a bag attachment means for grasping and securing a portion of the bag to the bag support member. Once the opposing lips of the bag are secured against opposing bag support members, the orifice of the bag will remain open due to tension generated by the respective bag support members, thus allowing the use of two hands to place items in the bag or remove contents from the bag.

Abstract: The present invention provides a metal ion scavenging procedure and antibody compositions for radioimmunoscintigraphy and cytotoxic radioimmunotherapy having chelator concentrations of greater than about 10.sup.-4 M which are optimized with respect to their metal binding capacity such that highly efficient labelling of the antibody is achieved in a simple one step procedure using readily available sources of radiometal ions.
