The Toxin Probes and Assays Core will provide analytical support to each of the four projects. Support will be in the form of (1) toxin standards, (2) anti-toxin antibodies and synaptosomes as reagents for specific binding assays, (3) toxin derivatives that may encompass metabolites, conjugates, and photolysis products, (4) Fourier transform infrared and nuclear magnetic and proton and carbon) resonance spectrometry of standards and synthetic metabolites or proto-products, and (5) high performance liquid chromatographic analysis. For Research Project 1, the core anticipates support items (1), photolytic (3), and (5) to be the most important. For Research Project 2, support items (1), (2), (3) and (5) will be essential. For Research Project (3) toxin derivatives that may encompass metabolites, conjugates, and photolysis products, (4) Fourier transform infrared and nuclear magnetic (proton and carbon) resonance spectrometry of standards and synthetic metabolites or proto- products, and (5) high performance liquid chromatographic analysis. For Research Project 1, the core anticipates support items (1), photolytic (3), and (5) to be the most important. For Research Project 2, support items (1), (2) , (3) and (5) will be essential. For Research Project 2, 3, support items (1) and (2) will provide the most benefit. For Research Project 4, support items (1) and (2) will be the most important. The core will also provide antibodies and reagent toxins to Facilities Core 2, the Immunocytochemistry Core, so that immunoperoxidase assays an be carried out relative to phagocytic accumulation and biomarker assay development. This relative to phagocytic accumulation and biomarker assay development. This latter effort will require synthesis of antibody- HRP conjugates and measurement of specific enzymatic activity per binding unit. To carry out this Program efficiently, Dr. Baden will oversee the core s functions, determine the level of effort to be expended on each project, identify the standards assays, and derivatives that will be of most use, and work with the 2 research associates to provide the materials and assay logistics and a timely manner. The two research associates will receive samples, isolate quantitatively and identify the components, develop synthetic methods to produce sufficient quantities for controlled experiments, and provide advice to individual projects pertaining to amounts of material to collect, methods of preservation, and methods of transport.

毒素探针和检测核心将为这四个项目提供分析支持。支持的形式包括 (1) 毒素标准品，(2) 作为特异性结合测定试剂的抗毒素抗体和突触体，(3) 可能包含代谢物、缀合物和光解产物的毒素衍生物，(4) 傅里叶变换标准品和合成代谢物或原始产品的红外和核磁以及质子和碳）共振光谱分析，以及（5）高效液相色谱分析。对于研究项目 1，核心预计支持项目 (1)、光解 (3) 和 (5) 是最重要的。对于研究项目 2，支持项目 (1)、(2)、(3) 和 (5) 是必不可少的。对于研究项目 (3) 可能包含代谢物、缀合物和光解产物的毒素衍生物，(4) 标准品和合成代谢物或原产物的傅里叶变换红外和核磁（质子和碳）共振光谱测定，以及 (5) 高高效液相色谱分析。对于研究项目 1，核心预计支持项目 (1)、光解 (3) 和 (5) 是最重要的。对于研究项目 2，支持项目 (1)、(2)、(3) 和 (5) 是必不可少的。对于研究项目 2、3，支持项目 (1) 和 (2) 将提供最大效益。对于研究项目 4，支持项目 (1) 和 (2) 将是最重要的。该核心还将为设施核心 2（免疫细胞化学核心）提供抗体和试剂毒素，以便进行与吞噬细胞积累和生物标志物测定开发相关的免疫过氧化物酶测定。这与吞噬细胞积累和生物标志物测定的发展有关。后一项工作需要合成抗体-HRP 缀合物并测量每个结合单位的特异性酶活性。为了有效地执行该计划，巴登博士将监督核心功能，确定每个项目的工作量，确定最常用的标准分析和衍生品，并与 2 名研究助理合作及时提供材料和化验物流。两名研究助理将接收样品，定量分离并鉴定成分，开发合成方法以生产足够数量的受控实验，并为各个项目提供有关收集材料量、保存方法和运输方法的建议。
