    摘要: A process for determining the presence of an antigen or antibody in a sample wherein said antigen or antibody exists in the form of an immune complex which comprises:

    A. contacting the immune complex originating from the sample suspected of containing immune complex with a dissociating buffer whereby said immune complex, if present, is dissociated into antigen and antibody;
    B. contacting a solid support which binds proteins with said dissociating buffer suspected of containing antigen or antibody and removing said buffer;
    C. washing said solid support;
    D. adding protein to fill unoccupied sites on said solid support;
    E. adding radioactively labeled or enzyme labeled antibody or antigen to said support, said labeled antibody or antigen corresponding to antigen or antibody on said solid support, incubating the resultant mass and washing the same;
    F. measuring the radioactivity or enzymatic activity associated with the solid support.

    摘要: Serum thymic factor (STF) occurs in minute amounts in blood, making its determination difficult. It has been found that peptides having a primary structure represented by the formula: wherein

    (1) X is H-Tyr-Gln-Ala-Lys and Y is a hydroxyl group,
    (2) X is pGlu-Ala-Lys(N e- Tyr-H) and Y is a hydroxyl group, or

    (3) X is pGlu-Ala-Lys and Y is TyrOH, can be radioactively labelled and used to determine STF. These peptides can be synthesized by bonding a predetermined amino acid or peptide to the N-end of H-Asn-OH, H-Asn-Tyr-OH or a peptide of the appropriate primary structure and terminating in -Asn-OH or -ASn-Tyr-OH at its C-end without protecting the carboxyl group at the C-end of said H-Asn-OH, H-Asn-Tyr-OH or peptide terminating in -Asn-OH or -Asn-Tyr-OH at its C-end, and as desired elongating the resulting peptide chain from the N-end by the bonding of further predetermined amino acid(s) and/or peptide(s), to obtain the desired peptide.

    摘要: Apparatus and method are provided for performing solid phase tests for mobile components in fluids, especially in vitro diagnostic tests. A solid phase device is used having a fixed component immobilized on its surface which is in contact with a fluid sample when inserted therein. The improvement involves utilizing a receptacle, into which the device is inserted, having the same fixed component immobilized on the inner surface of the receptacle. The test is performed by placing a fluid sample, having a mobile component reactive with the fixed component, into the receptacle and in contact with the insert for a period of time and measuring a change which is a function of the concentration of the mobile component.
