The mission of the SAXS Core facility is to provide support to research projects from CCR principal investigators (PIs), NIH intramural PIs, and extramural academic research groups/laboratories. The support includes providing routine access to the APS PUP SAXS/WAXS beamline and in-house SAXS instrument, and expertise in experimental design, data collection, processing, analysis, and interpretation. Our main focus is to determine the structure of biomacromolecules and their complexes in solution. The research subjects includes but not limited to structural studies of nucleic acids, proteins, protein assemblies, virus particles, lipid membranes, protein/DNA, and protein/RNA complexes. The COVID-19 pandemic has had a negative impact on the operation of the SAXS facility, because of laboratory shutdowns nationwide that prevents in-lab sample preparation and SAXS experiment for most of 2021. In-person SAXS experiments were only allowed to start by the SAXS beamline in May 2022.

SAXS 核心设施的使命是为 CCR 首席研究员 (PI)、NIH 校内 PI 和校外学术研究小组/实验室的研究项目提供支持。该支持包括提供对 APS PUP SAXS/WAXS 光束线和内部 SAXS 仪器的常规访问，以及实验设计、数据收集、处理、分析和解释方面的专业知识。我们的主要重点是确定溶液中生物大分子及其复合物的结构。研究课题包括但不限于核酸、蛋白质、蛋白质组装体、病毒颗粒、脂质膜、蛋白质/DNA、蛋白质/RNA复合物的结构研究。 COVID-19 大流行对 SAXS 设施的运营产生了负面影响，因为全国范围内的实验室关闭，导致 2021 年大部分时间无法进行实验室样品制备和 SAXS 实验。直到 2022 年 5 月，SAXS 光束线才允许进行现场 SAXS 实验。
