Patent number: 5939273Abstract: Compounds and libraries are labeled with a galactosyl epitope and then screened in accordance with an assay involving cells having a characteristic of interest. Conveniently, the screening may embody target cells, where the compounds are brought in contact with the cells. Each of the compounds carries with it the information of its identity or method of synthesis. After washing away non-specifically bound compounds, blood may be applied to the cells, whereby antibody binding to the galactosyl epitope initiates the complement cascade. Plaques are identified and the compound associated with the plaque identified. The formation of the plaque demonstrates that the compound has specific affinity for the target cell, binding of the compound to the cell does not interfere with binding of the antibody, and that the complex is capable of cytotoxic activity by means of the complement cascade.Type: GrantFiled: October 2, 1997Date of Patent: August 17, 1999Assignee: SangState Medical CorporationInventors: Alexander R.

Patent number: 5843440Abstract: Novel bifunctional reagents useful in reducing the biological effect of an undesirable blood-borne agent are provided. The reagents comprise conjugates of a first binding member specific for a blood-borne agent having a detrimental biological activity in a mammalina host, such as a growth factor, coagulation factor, enzyme, toxin, drug of abuse, microbe, autoreactive immune cell, infected or tumorous cell, joined to an second binding member specific for an anchor, where the anchor is a long-lived blood component, including cells, such as a erythrocyte, platelet or endothelial cell and serum proteins, such as albumin, ferritin, or steroid binding proteins. These conjugates find therapeutic use by coupling the agent and the blood component and thereby reducing the biological activity or effective concentration of free agent, modulating the volume of distribution of the agent, targeting the agent to sites of enhanced immune response, or facilitating agent clearance from the bloodstream.Type: GrantFiled: August 14, 1996Date of Patent: December 1, 1998Assignee: RedCell Canada, Inc.Inventors: Philippe Pouletty, Christine Pouletty

Patent number: 5534412Abstract: Methods and compositions are provided for the determination of cross-reactive alleles, where there is no antibody which will specifically distinguish between the two alleles. Particularly, the method employs an antibody which binds to the two alleles bound to a surface, an antibody specific for one of the alleles, a labeled conjugate which binds to a consensus sequence present in both alleles and positive and negative controls. By having an enhanced value where the interfering allele is present as compared to a value for the target allele, one can distinguish between the various alternatives involving the presence or absence of one or both alleles.Type: GrantFiled: September 29, 1994Date of Patent: July 9, 1996Assignee: SangStat Medical CorporationInventors: Philippe Pouletty, Chin-Hai Chang

Patent number: 5292641Abstract: The presence of alloantigen allelic products or antibodies to alloantigen allelic products is determined by employing a support to which alloantigen allelic products are bound, and combining a specimen which contains either the alloantigen allelic products or antibodies to alloantigen allelic products with a reagent comprising antibodies to the alloantigen allelic product(s) of interest. By combining the specimen, reagent and support, and determining the amount of antibody which binds to the support as compared to a negative control, the presence of the alloantigen antigen or anti-alloantigen is related to a reduced amount of antibody binding to the support. The amount of antibody may be determined by any convenient assay.Type: GrantFiled: December 13, 1991Date of Patent: March 8, 1994Assignee: SangStat Medical CorporationInventor: Philippe Pouletty
