Abstract:
This invention presents novel assay devices employing a capture reagent, involving a specific binding member attached to a charged substance, and a porous material containing a capture or reaction zone that is oppositely charged with respect to the capture reagent. In one embodiment, a test sample suspected of containing the analyte of interest is contacted with the capture reagent to form a charged capture reagent/analyte complex. The complex is then contacted to the oppositely charged capture or reaction zone to attract, attach, and immobilize the capture reagent/analyte complex. With an appropriate indicator reagent, both sandwich and competitive assays can be performed.
Abstract:
A method and a kit for the isolation and quantitative detection of a selected target nucleic acid sequence from solution employing two probes. A first probe is complementary to one portion of the target and is covalently attached to a first complexing agent (e.g., either an antigen or an antibody). The second probe is complementary to a different portion of the target and is associated with a reporter group. Following hybridization of the target and two probes in solution, a solid support coated with a second complexing agent (i.e., a corresponding antibody or antigen) capable of binding to the first complexing agent on the first probe is employed to immobilize the target-probe hybrid complex. A plurality of types of first probes may be used. Each type is attached to the same sort of complexing agent but each includes a nucleic acid sequence which is complementary to a different portion of the target.
Abstract:
A set of contiguous and partially overlapping cDNA sequences and polypeptides encoded thereby, designated as PCIGF and transcribed from prostate tissue, is described. These sequences are useful for the detecting, diagnosing, staging, monitoring, prognosticating, in vivo imaging, preventing or treating, or determining the predisposition of an individual to diseases and conditions of the prostate, such as prostate cancer. Also provided are antibodies which specifically bind to PCIGF-encoded polypeptide or protein, and agonists or inhibitors which prevent action of the tissue-specific PCIGF polypeptide, which molecules are useful for the therapeutic treatment of prostate diseases, tumors or metastases.
Abstract:
A set of contiguous and partially overlapping cDNA sequences and polypeptides encoded thereby, designated as BS247 and transcribed from breast tissue, are described. These sequences are useful for the detecting, diagnosing, staging, monitoring, prognosticating, in vivo imaging, preventing or treating, or determining the predisposition of an individual to diseases and conditions of the breast, such as breast cancer. Also provided are antibodies which specifically bind to BS247-encoded polypeptide or protein, and agonists or inhibitors which prevent action of the tissue-specific BS247 polypeptides, which molecules are useful for the therapeutic treatment of breast diseases, tumors or metastases.

Abstract:
Nouveaux procédés d'analyse faisant appel à un réactif de capture, mettant en jeu un premier membre de fixation normalement associé à une substance anionique polymérique, un matériau en phase solide contenant un lieu de réaction constitué d'une substance cationique polymérique d'une teneur en azote d'au moins environ 2 %. Dans un mode de réalisation, un échantillon à analyser dans lequel on soupçonne la présence de l'analyte recherché peut être mis en contact avec le réactif de capture pour former un complexe chargé contenant le réactif de capture et l'analyte. Le complexe est ensuite mis en contact avec la phase solide de charge opposée pour attirer, fixer et immobiliser le complexe réactif de capture/analyte. L'utilisation d'une substance polycationique, d'une teneur en hydrogène d'au moins environ 2 % (à l'exclusion des contre-ions), dans la préparation d'une phase solide correctement chargée fournit une phase solide qui peut être soumise à un plus grande nombre de manipulations, tels que les lavages multiples, sans perdre la capacité d'attirer et de retenir le réactif de capture.
