    摘要: An instrument (50) automatically determines the concentrations of HDL cholesterol, LDL cholesterol, total cholesterol and triglycerides for a sample (80) of whole, anticoagulated blood placed in a doughnut shaped container (10). The sample (80) is first separated into its blood cell and plasma (84) constituents using high speed centrifugation (54) and a thixotropic gel (82). Part of the plasma (84) is then deposited in an HDL separation chamber (14) where LDL cholesterol and VLDL cholesterol are precipitated by a reagent and the precipitant is sedimented by high speed centrifugation (54) against V-shaped grooves (40) in the outermost wall (38) of the HDL separation chamber (14). Part of the plasma (84) is diluted ten-fold. The supernatant in the HDL separation chamber is then placed in a cuvette reaction chamber (b 18) where it reacts with a cholesterol reagent. The diluted plasma is placed in two other cuvette reaction chambers (18) where it reacts with chloesterol and triglycerides reagents, respectively. Calibration reagents, stored in storage chambers (20), react in two other cuvette reaction chambers (18) to establish a reference absorbance. A pipettor (58) handles all the fluid transfers in the doughnut shaped container (10) and operates in conjunction with a slow speed motor (56) that precisely moves the spindle (52) on which the doughnut shaped container (10) is mounted. A colorimetric measuring system (70, 72, and 74) monitors the absorbance of chemical reactions occurring in the cuvette chambers (18).

    摘要: An improved pipette probe in an automated chemical analysis system is provided, along with a pipette tip wash protocol to reduce carryover. The pipette tip comprises an elongated stainless-steel barrel which houses a polytetrafluoroethylene tube. The non-wettable properties of polytetrafluoroethylene inhibit fluid adhesion and thereby reduce carryover. The pipette tip is swaged at a fluid dispensing end to a restrictive diameter for good pipetting precision and accuracy. A novel wash protocol is also provided which includes a novel wash solution comprising quantities of Triton X-100 nonionic detergent, Diethanolamine, and NaCl.

    摘要: An automated immunoassay analyzer includes a computer controlled instrument (10) and display (16). The display (16) provides a real-time presentation of all operations being performed within the instrument (10). A large number of samples can be loaded into the instrument (10), and the order of testing the samples can be rearranged according to a priority determined by the operator at any time. A wide variety of immunoassays can be performed on each sample and several different immunoassays can be performed on any one sample. Information related to the type of immunoassays being performed on particular samples is collected by a bar code reader (44) and this information is conveyed to the computer (12) for presentation on the display (16). The computer (12) tracks the progress of each immunoassay through the reaction circuit to the detection station (46). The time to completion for particular immunoassays as well as the concentration information for recently completed immunoassays is provided in a readily usable format. The immunoassay automation process is improved by performing the washing operation with an assay tube (26) which allows water to be expelled by centrifugal forces generated by rotating the tube about its longitudinal axis; rather, than by using more conventional aspirating equipment. Bound label is detected by chemiluminescence using a photomultiplier tube (96).

    摘要: A method for conducting immunoassays in an automated fashion is disclosed. A biological fluid under test is placed in a tube (11) which has a solid support (18) therein to which a specific analyte in the biological fluid will be selectively bound. After the analyte in the biological fluid is bound to the solid support (18), the tube (11) is rotated at high speed about its longitudinal axis causing the biological fluid to be transported up the inside walls of tube (11), over the open terminal end (16), and into waste chamber (15). The solid support (18) with the bound analyte may easily be washed by flushing the inside of tube (11) with water or other suitable fluids and rotating the tube (11) at high speed about its longitudinal axis.

    摘要: A centrifuge vessel for performing immunoassays, affinity chromatography, and like experiments includes a center tube and an outer waste chamber. A biomaterial is held within the center tube and is capable of binding specific analytes in test samples. In operation the centrifuge vessel is rotated at high speed about its longitudinal axis, thereby causing all fluid within the center tube to be transported into the outer waste chamber while the analyte of interest remains bound to the biomaterial positioned within the center tube In the centrifuge vessel, a cap connected to the outer waste chamber and extending over the center tube includes structure for preventing waste fluid expelled to the waste chamber from re-entering the center tube. In a first embodiment, the cap is either constructed from or the inside surface is coated with a hydrophobic material which repels fluids back into the waste chamber. In a second embodiment, the cap includes a dam which allows fluid to pass into the waste chamber but blocks the migration of waste fluid back to the center tube. In a third embodiment, the cap includes a sponge that allows fluids in the center tube influenced by the intense centrifugal forces generated during high speed rotation to pass into the waste chamber, but which prevents fluids in the waste chamber, which are influenced by relatively weaker forces, from returning to the center tube.
