    摘要: Surfactants bound to a ligand and dissolved in a single phase aqueous solution form a precipitate when a multivalent antiligand is added to the solution. This invention can be used in an affinity precipitation test procedure (and kit) for detecting the presence or absence of a multivalent antiligand in a sample suspected of containing the multivalent antiligand, in an affinity precipitation inhibition test procedure (and kit) for detecting the presence or absence of a target ligand in a sample suspected of containing the target ligand, and in a process for separating a multivalent antiligand from a crude material containing the multivalent antiligand.

    摘要: A method of immunoassay for analyzing a bodily fluid for the presence of an analyte relies on observing substantially the entire course of a precipitin reaction from initiation to substantial completion of the precipitation, defining a mathematical function which represents the amount of precipitation versus time and contains constants which can be adjusted so that the function matches the observed precipitation versus time curve, and fitting the observed data to the mathematical function by adjusting the constants so that the mathematical function matches the observed precipitation versus time curve as closely as possible. Values for the maximum rate of precipitation and for the time interval from initiation of the precipitation to the time of maximum rate of precipitation are calculated from the mathematical function. A reference curve is generated using standard containing known concentrations of analyte according to conventional analytical procedures. The values so calculated for the parameters of the precipitation can then be used to determine whether a given sample presents a condition of antigen (analyte) excess and must be discarded or a condition of antibody excess which can be used in conjunction with the reference curve to report a valid concentration of analyte.

    摘要: A sensitive radioimmunoassay for chlorpromazine is described. To prepare the chlorpromazine selective antiserum, an antigen is made comprising chlorpromazine covalently bonded to an immunogenic carrier material through a diazo containing linking group and the antigen is injected into a suitable host mammal to elicit the desired antiserum. A preferred linking group is diazophenylcarbonyl while bovine serum albumin is a preferred immunogenic carrier material.

    摘要: A trifunctional conjugate is providing having three chemical moieties attached through a spacer moiety. At least two of the chemical moieties are relatively small molecules, usually less than about 7,000 Daltons in size. The spacer moiety is selected to impart certain steric properties to the conjugate. In one embodiment, the binding of a macromolecular specific binding partner to one of the chemical moieties sterically inhibits the binding of a different macromolecule to another chemical moieties. In another embodiment, the binding of a first chemical moiety to a macromolecule restricts the subsequent binding of a second tridentate member to a proximate location on the same macromolecule. The three chemical moieties are preferably a nitrophenylazido residue, a phenyl boronic acid residue, and a solid support or a label such as biotin. The spacer is preferably cysteine, lysine, glutamic acid, pyroglutamic acid, S-acetylmercaptosuccinic anhydride or .omega.-carbobenzoxylysine. The conjugate is useful in immunoassays and for targeted labeling of proteins.
