    摘要: Sacs comprising a compound having a hydrophilic peptide radical are prepared and are believed to have improved stability as a result of hydrogen bonding. The sacs, including a detectable marker and derivatized with a ligand may be used as a tracer in an assay.At least a portion of the sac is formed from a compound having the following structural formula:X-Y-Z,whereinX is a hydrophobic radical;Y is a hydrophilic peptide; andZ is a radical which includes a non-hydrolyzable polar group.

    摘要: Novel non-competitive assay techniques have been developed which not only improve sensitivity, but also are convenient and less susceptible to interfering factors. They are compatible with existing instruments and can be run in one or more test tubes. The analyte is reacted with labeled specific binder, after which the mixture is reacted with (1) an insoluble material attached to an analyte derivative and (2) a solid phase carrying a binder. The solid phase is then separated, and the label attached to the solid phase is measured. Variations of the procedure include the use of a reversible bridge for attaching the insoluble material to the analyte mimic and the conduct of the assay in various porous media, such as paper, chromatographic and electrophoretic media, and dipsticks.

    摘要: A method for processing multi-phasic dispersions is provided. The method comprises providing a multi-phasic dispersion, the dispersion including dispersed and continuous phases, the dispersion comprising solid microparticles, providing a non-solvent, combining the multi-phasic dispersion and the non-solvent, and selectively effecting migration of the dispersed phase into or through the non-solvent such that the microparticles are separated from the dispersion.
