Abstract: Novel assays for ligands and receptors employing novel compounds that are conjugates of squarates dyes and members of a specific binding pair (sbp) are disclosed. The sbp members are selected from the group consisting of ligand and its complementary receptor. The sbp member is covalently or non-covalently bound to the squarate dye, which usually has an absorption maximum greater than 600 nanometers. The novel conjugates are employed in assays for determining the presence or amount of an sbp member analyte in a sample suspected of containing such analyte. Kits comprising such novel conjugates are also disclosed.

Abstract: A method is disclosed for determining an analyte in a sample suspected of containing the analyte. The analyte is a member of a specific binding pair (sbp) consisting of ligand and complementary receptor. The method comprises combining in an aqueous medium (1) said sample, (2) a first reagent comprising a non-dispersed surface to which is bound an sbp member that becomes bound to the surface in relation to the amount of analyte in the sample. The volume of the aqueous medium containing the above reagents is sufficiently large to allow complete immersion of the first reagent therein and determination of the analyte but not so large to result in substantial interference in the determination upon addition of a second reagent reactive with the conjugate of enzyme and sbp member and capable of generating a signal. The second reagent is present in a medium of sufficient volume to substantially increase the volume of the liquid medium and reduce interference in the determination.

Abstract: The present invention is concerned with a method for determining the presence of a malignant condition at a locus of interest. An exfoliative cell specimen obtained from the locus is contacted with an antibody specific for an antigenic site that is usually only found in the specimen when a malignant condition is present. The contact is made under conditions for detectable binding of the antibody to such antigenic site. After contact, the presence of binding of the antibody to the antigenic site is observed. The binding of the antibody is related to the presence of a malignant condition at the locus. The invention finds utility, for example, in the detection of cervical carcinoma.
