项目摘要
Project Summary
The ultimate goal in the field of proteomics is single-molecule, high-accuracy, de novo protein sequencing.
Unfortunately, current proteomics technologies are costly, and lack the sensitivity, dynamic range, throughput,
scale, and accuracy needed to meet this goal. During this project, we will begin examining the technological
components and methods required to enable state-of-the-art protein sequencing and characterization. More
specifically, we will develop methods for controllably translocating a protein through a nanopore reader such that
the protein can be sequenced. Nanopore-based sequencing provides a path to characterizing both high- and
low-abundance proteins by sequencing proteins one molecule at a time, but with high accuracy, sensitivity and
throughput needed to cover the wide dynamic range in protein abundance in the proteome. During this project,
we will develop a completely new nanopore-based technology for de novo protein sequencing. We will develop
and build a novel protein sequencing system prototype, fully assess and optimize the associated
workflow/methodology for highly controlled and versatile protein/peptide characterization, and demonstrate initial
sequencing for various proteins and peptides. At the conclusion of this project, we will have successfully
demonstrated feasibility for a practical nanopore-based protein sequencing concept.
项目摘要
蛋白质组学领域的最终目标是单分子、高精度、从头蛋白质测序。
不幸的是,目前的蛋白质组学技术是昂贵的,并且缺乏灵敏度、动态范围、通量,
规模和精度需要达到这一目标。在这个项目中,我们将开始检查技术
我们提供了实现最先进的蛋白质测序和表征所需的组件和方法。更
具体地,我们将开发用于通过纳米孔读取器可控地易位蛋白质的方法,
可以对蛋白质进行测序。基于纳米孔的测序提供了一种表征高分子和
低丰度蛋白质测序蛋白质一个分子的时间,但具有高准确性,灵敏度和
在蛋白质组中覆盖蛋白质丰度的宽动态范围所需的通量。在这个项目中,
我们将开发一种全新的基于纳米孔的技术,用于从头蛋白质测序。我们将开发
并建立了一个新的蛋白质测序系统原型,充分评估和优化了相关的
用于高度受控和通用的蛋白质/肽表征的工作流程/方法,并展示了初始的
各种蛋白质和肽的测序。在这个项目结束时,我们将成功地
证明了基于纳米孔的蛋白质测序概念的可行性。
