Prioritization of reagents (tools) to be produced will be established by surveying the larger scientific community and cooperating with other similar international efforts to avoid redundancy and target the most useful reagents for research scientists. Commercial companies will also be surveyed. Bioactive cytokines and chemokines and cell surface CD molecules, antibodies, and T cell receptors will be produced in expression systems in two main labs for poultry and mammals and by the two co-PDs for fish. The expression of these proteins will depend upon provision of cDNA from appropriate cells or tissues from the co-PD labs who are specialists in particular species. RT-PCR using primers based on available sequences or from homologous genes in other related species will be done to obtain the entire gene sequence. The recombinant molecules will be used to prime mice for production of monoclonal antibodies or rabbits for polyclonal antibodies in a centralized lab. After identifying reactive antibodies initially, both the recombinant molecules and the antibodies to them will be evaluated for efficacy in the species specialist labs in a variety of in vitro assays. This project will have oversight by an advisory board composed of industry partners, USDA national program directors and other international reagent-generating groups. The reagents will be provided to the scientific community by depositing in commercial cell banks and encouraging generation and distribution through commercial vendors. BL-1, 9/27/06.
