    摘要: The present invention provides monoclonal antibodies specific to and distinguish between hemoglobin S and hemoglobin A and methods for their production and use. These antibodies are capable of distinguishing between two hemoglobin types which differ from each other by only a single amino acid residue. The antibodies produced according to the present method are useful as immunofluorescent markers to enumerate circulating red blood cells which have the property of altered expression of the hemoglobin gene due to somatic mutation in stem cells. Such a measurement is contemplated as an assay for in vivo cellular somatic mutations in humans. Since the monoclonal antibodies produced in accordance with the instant invention exhibit a high degree of specificity to and greater affinity for hemoglobin S, they are suitable for labeling human red blood cells for flow cytometric detection of hemoglobin genotype.

    摘要: Methods are described for making specific monoclonal antibodies useful for detection of cyclodienes in foods and environmental samples. Monoclonal antibodies specifically reactive with cyclodienes can detect accumulated pesticides in food, tissue or environmental samples. Extraction and preparation of organic samples for immunoassay in a polar-nonpolar reaction medium permits detection of halogenated organic ring structures at concentrations in samples.

    摘要: Monoclonal antibodies are described which have specific affinities for halogenated nucleoside analogs and are preferentially selective for one particular halogen. Such antibodies, when incorporated into immunochemical reagents, may be used to identify and independently quantify the cell division character of more than one population or subpopulation in flow cytometric measurements. Independent assessment of division activity in cell sub-populations facilitates selection of appropriate time and dose for administration of anti-proliferative agents. The hybridomas which secrete halogen selective antibodies and the method of making them are described.

    摘要: Hybridoma cell lines have been generated which produce and secrete monoclonal antibodies which selectively bind to the ceftiofur. These hybridomas may be obtained by using as an immunization agent or immunogen, desfuroyl ceftiofur which has been conjugated to an immunogenic carrier. Ceftiofur in biological samples may be detected and quantified by contacting the sample with the antibodies to form a ceftiofur/antibody immunocomplex when ceftiofur is present, which immunocomplex may then be detected. The monoclonal antibodies may also be incorporated into kits for the detection and quantification of ceftiofur.
