Abstract:
A method for replacing a first sample carried on a moving secondary conveyor onto a moving primary conveyor at a potential interference point while the primary conveyor is tranporting a second sample.
Abstract:
A system for automatically testing a sample aliquot retained in temporary storage in environmentally controlled conditions on an automated clinical analyzer for a period of time without requiring operator intervention.
Abstract:
An improved mounting clamp adapted to simultaneously secure flat ribbon cables and a number of fluid tubes to a surface and having a locking feature to facilitate assembly and release.
Abstract:
A fluid handling system adapted to provide storage and supply of a number of liquid solutions to an automatic clinical analyzer having three different bottle-like containers, a collapsible plastic-metal-plastic pouch having a mouth-like opening, a fitment to be sealed within mouth-tike opening, a septum within the fitment, and open meal band or cap to seal the septum into the fitment.
Abstract:
Methods and compositions are disclosed for reducing non-specific binding in a binding assay for the determination of an analyte in a sample where one of the reagents for conducting the binding assay comprises a solid support comprising a polysaccharide. The method comprises including in an assay medium for conducting the binding assay a soluble compound comprising a protein linked to a polysaccharide. Also disclosed are methods and compositions for determining the presence and/or amount of an analyte in a sample suspected of containing the analyte. The methods include as reagents a solid support comprising a polysaccharide and a soluble compound comprising a protein linked to a polysaccharide.
Abstract:
A re-sealing puncturable closure for use with vials having calibration or control solutions chemicals therein adapted for use in a manner that advantageously minimizes evaporation from a solution vial prior to and subsequent to aspiration of solution therefrom.
Abstract:
A liquid aspiration method which includes aspirating partial aliquots of liquid at a number of different depths of penetration of a pipette tip (20) into a liquid (14). The different depths (dashed lines 1-8) are selected so that partial aliquot segments are obtained throughout the entire depth of sample, optionally excluding the extreme top and bottom levels.
Abstract:
Methods, compositions and kits are disclosed. Enzyme conjugates of Formula (I) are employed in assays for the determination of an methylenedioxyamphetamine, a methylene-dioxyethamphetamine, and/or a methylenedioxymethamphetamine. Immunogenic conjugates of Formula I are employed to prepare antibodies for an methylenedioxyamphetamine, a methylenedioxyethamphetamine, and/or for a methylene- dioxymethamphetamine for use in assays for the determination of an methylenedioxyamphetamine, a methyl enedioxyethamphetamine, and/or a methylene-dioxymethamphetamine. The enzyme conjugates may also be employed to screen antibodies for use in such methods.
Abstract:
Methods, compositions and kits are disclosed. The methods are directed to determining the presence of entactogen analytes such as, for example, 3,4-methylenedioxamphetamine (MDA), 3,4-methylenedioxy-methamphetamine (MDMA), 3,4-methylenedioxy-ethylamphetamine (MDEA) and 4-hydroxy-3-methoxy-methamphetamine (HMMA). The method comprises providing in combination in a medium (i) a sample suspected of containing the compound and (ii) an antibody raised against a compound of Formula I that comprises a protein. The medium is examined for the presence a complex comprising the compound and the antibody where the presence of such as complex indicates the presence of the compound in the sample. In one aspect of the above embodiment, the combination further comprises a label conjugate of the compound Formula I.
