GeneChip Automation and MegAllele System for Microarray Analysis at Yale Univ.

描述（由申请人提供）：Affyscore基因芯片微阵列技术在新阵列、表达和基因分型测定以及改进的仪器的开发方面不断发展。阵列的大小和种类的增加以及它们的指数增长的使用极大地加剧了对更先进和更高度自动化的仪器的需求。微阵列分析的自动化方法劳动密集度较低，每个样品的成本较低，可重复性更好，并且更容易在不同的实验室中标准化。凯克基因芯片设备被大量用于分析基因表达和基因型DNA。自2003年成立以来，基因芯片设施已经分析了来自耶鲁大学和其他22个机构的115名研究人员的4,000多个样本。在过去三年中，对服务的需求每年增长50%以上。此外，凯克基因芯片资源是新资助的耶鲁大学神经系统研究微阵列中心的一部分。作为负责为NIH神经科学蓝图中15个研究所的10，000名神经科学家提供微阵列技术的四个实验室之一，最近的这一奖项将大大增加对Keck基因芯片服务的需求，并将确保所要求的仪器被充分利用。在这方面，所要求的基因芯片自动化平台和MegAllele系统将使凯克实验室能够满足对现有服务的预期需求增长，使其用户能够进行定制基因分型，并通过减少操作员之间的差异来提高所得数据的可靠性。资助这一应用将使基因芯片资源能够将最先进的微阵列技术应用于几种重要疾病，包括癫痫、精神疾病、自闭症、心血管疾病和癌症。该提案的优势包括非常多样化和富有成效的研究者用户群; PI在监督Keck Affyoung Lab及其相关的耶鲁/NIH微阵列中心方面的经验; Co-PI，K.威廉姆斯，在监督许多大型，多研究者NIH合同和中心; PI和其他关键人员的生物技术，统计和数据库专业知识;以及广泛的基础设施和补充支持凯克实验室及其相关的NIH资助的中心（例如，耶鲁/NIDA神经蛋白质组学中心和新的生物医学高性能计算中心）。如果有机会，PI和关键人员将尽一切努力确保所要求的仪器对生物医学研究产生非常积极和持久的影响，这种影响将远远超出耶鲁大学。

DESCRIPTION (provided by applicant): Affymetrix GeneChip microarray technology is constantly evolving with regard to the development of new arrays, expression and genotyping assays, and improved instrumentation. The increase in the size and variety of arrays coupled with their exponentially increasing use has greatly exacerbated the need for more advanced and more highly automated instrumentation. Automated methods for microarray analysis are less labor-intensive, less costly on a per sample basis, more reproducible, and are much easier to standardize across different laboratories. The Keck GeneChip facility is very heavily used to analyze gene expression and to genotype DNA. Since its founding in 2003, the GeneChip facility has analyzed >4,000 samples from >115 investigators at Yale and at 22 other institutions. The demand for services has increased by >50% in each of the last three years. Additionally, the Keck GeneChip Resource is part of the newly funded Yale Microarray Center for Research on the Nervous System. As one of four laboratories responsible for providing microarray technologies to 10,000 neuroscientists from 15 institutes in the NIH Neuroscience Blueprint, this recent award will very substantially increase the demand for Keck GeneChip services and will ensure that the requested instrumentation is used to its full capacity. In this regard, the requested GeneChip Automation Platform and MegAllele System would allow the Keck Lab to meet the anticipated increase in demand for existing services, to bring custom genotyping within reach of its users, and also would improve the reliability of the resulting data by reducing operator-to-operator variability. Funding this application would enable the GeneChip Resource to bring state-of-the-art microarray technologies to bear on several important diseases including epilepsy, psychiatric disorders, autism, cardiovascular disorders, and cancer. The strengths of this proposal include a very diverse and productive investigator user base; the experience of the PI in overseeing the Keck Affymetrix Lab and its associated Yale/NIH Microarray Center; the experience of Co-PI, K. Williams, in overseeing numerous large, multi-investigator NIH contracts and Centers; the biotechnological, statistical and database expertise of the PI and other key personnel; and the extensive infrastructure and complementary support from the Keck Lab and its associated NIH-funded Centers (e.g., the Yale/NIDA Neuroproteomics Center and the new Center for High Performance Computation in Biomedicine). If given the opportunity, the PI and key personnel will do absolutely everything in their power to ensure that the requested instrumentation has a very positive and long-lasting impact on biomedical research that will extend well beyond Yale.
