摘要: Solid supports for chemiluminescent assays are provided. The solid support includes a plurality of probes covalently or physically attached to the support surface and a chemiluminescent enhancing moiety incorporated onto the surface or into the bulk of the support. The solid support can be a multi-layered support including an upper probe binding layer (e.g., an azlactone polymer layer or porous functional polyamide layer) adjacent to a cationic microgel layer. The azlactone-functional polymer can be a copolymer of dimethylacrylamide and vinylazlactone crosslinked with ethylenediamine. The cationic microgel layer can be a cross-linked quaternary onium salt containing polymer. A method and a kit for conducting chemiluminescent assays using the solid supports is also provided. The kit comprises a dioxetane substrate, a biopolymer probe-enzyme complex, and a solid support. The solid support can be an azlactone functional polymer layer adjacent to a cationic microgel layer; a porous polyamide functional layer adjacent to a cationic microgel layer; or a quaternized azlactone functional polymer layer.

摘要: Fluorescent phenyl xanthene dyes are described that comprise any fluorescein, rhodamine or rhodol comprising a particular C9 phenyl ring. One or both of the ortho groups on the lower C9 phenyl ring is ortho substituted with a group selected from alkyl, heteroalkyl, alkoxy, halo, haloalkyl, amino, mercapto, alkylthio, cyano, isocyano, cyanato, mercaptocyanato, nitroso, nitro, azido, sulfeno, sulfinyl, and sulfino. In one embodiment, halo and/or hydroxy groups are used. Optimal dyes contain a lower C9 phenyl ring in which both ortho groups are the same and the lower ring exhibits some form a symmetry relative to an imaginary axis running from the phenyl rings point of attachment to the remainder of the xanthene dye through a point para to the point of attachment. The phenyl xanthene dyes may be activated. Furthermore, the phenyl xanthene dyes may be conjugated to one or more substances including other dyes. The phenyl xanthene dyes are useful for a number of purposes, including labels for use in automated DNA sequencing as well the formation of fluorescent “bar codes” for polymeric particles used in the multiplexed analysis of analytes.

摘要: The invention provides uncharged water-soluble silica-adsorbing polymers for suppressing electroendoosmotic flow and to reduce analyte-wall interactions in capillary electrophoresis. In one aspect of the invention, one or more of such polymers are employed as components of a separation medium for the separation of biomolecules, such as polynucleotides, polysaccharides, proteins, and the like, by capillary electrophoresis. Generally, such polymers are characterized by (i) water solubility over the temperature range between about 20° C. to about 50° C., (ii) concentration in a separation medium in the range between about 0.001% to about 10% (weight/volume), (iii) molecular weight in the range of about 5×103 to about 1×106 daltons, and (iv) absence of charged groups in an aqueous medium having pH in the range of about 6 to about 9. In one embodiment, polymers of the invention are selected from the group consisting of polylactams, such as polyvinylpyrrolidone; N,N-disubstituted polyacrylamides; and N-substituted polyacrylamides. In accordance with the method of the invention, a sufficient amount of polymer adsorbs to the capillary surface to establish a zone of high viscosity that shields the analyte from the wall and impedes the movement of an electrical double layer under an electric field.
