Patent number: 5089383Abstract: Methods and compositions are provided for assays involving members of a specific binding pair ("sbp members") and members of a signal producing system ("sps members"). The signal producing system is capable of producing a detectible signal in relation to the presence or amount of an analyte in a sample suspected of containing the analyte. Exemplary of sps members are enzymes and enzyme substrates, which react with each other to produce a signal. The improvement of the present invention comprises temporarily delaying the production of the signal without subsequent reagent addition. The delay can be achieved by employing an inhibitor which can be an alternate substrate for the enzyme or a compound which reacts with the product of the enzyme and its substrate in an effective amount.Type: GrantFiled: December 1, 1988Date of Patent: February 18, 1992Assignee: Syntex (U.S.A.)

Patent number: 5076950Abstract: A method is disclosed for separating a substance from a liquid medium. The method comprises combining the liquid medium containing the substance with magnetic particles under conditions for non-specific chemical binding of the magnetic particles. Thereafter, the medium is subjected to a magnetic field gradient to separate the particles from the medium. The preferred non-specific binding is achieved as the result of charge interactions between the particles usually by means of a polyionic reagent. The method of the invention has particular application to the separation of cells and microorganisms from aqueous suspensions and also to the determination of an analyte in a sample suspected of containing the analyte. The analyte is a member of a specific binding pair (sbp). The sample is combined in an assay medium with magnetic particles and a sbp member complementary to the analyte.Type: GrantFiled: June 5, 1990Date of Patent: December 31, 1991Assignee: Syntex (U.S.A.)

Patent number: 5071774Abstract: A method for determining the presence of a specific binding member bound to first particles in a liquid medium is disclosed. The method comprises providing in combination (1) a liquid medium suspected of containing a specific binding member bound to first particles, (2) means for agglutinating the first particles in relation to the presence of the specific binding member, and (3) second particles having the same or a different specific binding member for said means for agglutinating bound thereto, thereby providing for said means to agglutinate the second particles. Agglutination of the first and second particles are separately detectible and distinguishable by spectroscopic measurement. The medium is incubated and agglutination of each of the particles is determined spectroscopically without separating the first and second particles.Type: GrantFiled: June 23, 1988Date of Patent: December 10, 1991Assignee: Syntex (U.S.A.)

Patent number: 5068198Abstract: Assay methods and compositions are provided for determining an analyte in a sample suspected of containing the analyte. The composition comprises in a novel single liquid reagent at least one specific binding pair (sbp) member and its complementary member wherein at least one sbp member is reversibly confined in a material that temporarily renders the confined sbp member incapable of binding with its complementary sbp member. At least one of the sbp members is bound to a member of a signal producing system capable of producing a detectable signal in relation to the amount of analyte in the sample. The confinement is reversed, any remaining members of the signal producing system are added, and the signal produced in relation to the amount of analyte is measured. Examples of the confining material are lipid bilayers, cells and gels.Type: GrantFiled: January 13, 1989Date of Patent: November 26, 1991Assignee: Syntex (U.S.A.) Inc.Inventors: Ian Gibbons, Edwin F.
