DESCRIPTION (provided by applicant): The overall objective of this NCRR Shared Instrument Grant application is to upgrade and update a heavily-used Institutional Shared DNA Sequencing and Genotyping Core (DNAcore) with an ABI 3730xl DNA Analyzer to 1) lower costs of DNA sequencing and genotyping, 2) increase sequencing read-length and quality, and to 3) provide the new high-throughput ABI SNPlex method for SNP analysis. The requested ABI 3730xl DNA Analyzer is the current state-of-the-art capillary array analyzer that will fulfill all these goals and provide the economy and flexibility needed to satisfy the multitude of user projects requiring our shared resource facility. Of great importance to our investigators working on gene association projects, it will support low to high throughput genotyping utilizing a wide variety of approaches including STR-based linkage, single SNP analyses, allele quantitation by SNaPshot assays, and high throughput genotyping with 48-plex SNPlex assays. This upgrade to our busy shared sequencing, genotyping and oligonucleotide synthesis core facility at Mount Sinai will replace the ageing ABI 3700 platform that is too expensive to run due to its much greater use of reagents, its downtime due to hardware failures, its inability to support the SNPlex assay and its reduced signal sensitivity and uniformity relative to the new ABI 3730xl. This application is strengthened by the previous 10 years of experience of its Principal Investigator in providing high-quality DNA sequencing, genotyping, mutation detection and oligonucleotide synthesis for rapidly increasing numbers of NIH and other investigators at Mount Sinai. The DNAcore provides in-house expertise and consultation services for all sequencing, genotyping, positional cloning, mutation detection, and LOH projects. Equitable, cost-effective and responsive utilization of the requested instrumentation will be promoted through the DNAcore's Local Advisory Committee. They will also identify and recommend novel strategies, technologies, instrumentation, and resources to further facilitate and foster cutting-edge research. The Dean for Research will support service contracts and provide $100K towards the purchase of the requested ABI 3730xl, which with the $65K trade-in for the old ABI 3700 will make this request more cost effective. In addition, the Dean will support technician salaries after another grant terminates next year. With the requested ABI 3730xl DNA Analyzer, the DNAcore will continue to meet intense needs of our over 200 investigators with over 250 NIH grants for economical and accessible on-site sequencing and genotyping services to speed gene discovery, gene structure analysis, mutation characterization, analysis of vector constructs, linkage analysis, genome scanning, LOH studies, etc. In summary, the requested equipment upgrade will fit synergistically with existing resources and our Dean's major genomics initiatives to enhance research productivity by reducing costs of these key services to investigator's grant funds and providing higher quality sequencing and hitherto unavailable analyses to support high-throughput genomic scans.

描述（由申请人提供）：这项NCRR共享仪器拨款申请的总体目标是用ABI 3730xl DNA分析仪升级和更新一个被广泛使用的机构共享DNA测序和基因分型核心（dacore），以达到以下目的：1)降低DNA测序和基因分型的成本，2)增加测序的读长和质量，以及3)提供新的高通量ABI SNPlex方法进行SNP分析。所要求的ABI 3730xl DNA分析仪是当前最先进的毛细管阵列分析仪，将实现所有这些目标，并提供所需的经济和灵活性，以满足需要我们共享资源设施的众多用户项目。对于我们从事基因关联项目的研究人员来说，它将支持低通量到高通量的基因分型，包括基于str的连锁、单SNP分析、通过SNaPshot检测的等位基因定量，以及使用48-plex SNPlex检测的高通量基因分型。此次对我们繁忙的共享测序、基因分型和寡核苷酸合成核心设施的升级将取代老化的ABI 3700平台，该平台由于使用更多的试剂而过于昂贵，由于硬件故障而停机，无法支持SNPlex检测，并且相对于新的ABI 3730xl，其信号灵敏度和均匀性降低。在过去的10年里，我们的首席研究员为快速增长的NIH和西奈山的其他研究人员提供了高质量的DNA测序、基因分型、突变检测和寡核苷酸合成，这一应用得到了加强。dacore为所有测序、基因分型、定位克隆、突变检测和LOH项目提供内部专业知识和咨询服务。将通过DNAcore的当地咨询委员会促进对所要求仪器的公平、具有成本效益和反应迅速的利用。他们还将确定和推荐新的战略、技术、仪器和资源，以进一步促进和促进前沿研究。研究主任将支持服务合同，并提供10万美元用于购买所要求的ABI 3730xl，其中6.5万美元用于旧ABI 3700的交易将使该请求更具成本效益。此外，院长将在明年另一笔补助金终止后支持技术人员的工资。凭借ABI 3730xl DNA分析仪，DNAcore将继续满足我们200多名研究人员的强烈需求，并获得250多笔NIH拨款，为经济和可访问的现场测序和基因分型服务，以加快基因发现，基因结构分析，突变表征，载体构建分析，连锁分析，基因组扫描，LOH研究等。总之，所要求的设备升级将与现有资源和院长的主要基因组学计划协同配合，通过降低这些关键服务的成本来提高研究效率，研究者的资助资金，提供更高质量的测序和迄今为止不可用的分析，以支持高通量基因组扫描。
