BioCAT is offering its ninth intensive HOW-TO course in BioSAXS. Students will have four days of virtual lectures and hands-on software tutorials on the basics of BioSAXS data collection and processing from expert practitioners in the field. Students will also be able to mail in samples for data collection on the BioCAT beamline (Sector 18 at the APS) before the course, and there will be time during the workshop to get help with analysis of their own data.
The course will take place from 2/28/23 to 3/3/23 and is entirely virtual (via Zoom). See the schedule below for details.
Registration
All participants this year will be remote participants. The course will provide a virtual set of lectures and tutorials via Zoom, and participants will be able to mail in samples for SAXS data collection at BioCAT the week before the workshop. Participants will be able to ask questions during both lectures and tutorials, and will have time to get help with analysis of the data collected from their mail-in samples. They will also receive downloads of all course materials, including lecture slides and tutorials.
Note: This course is intended for researchers interested in scattering from monodisperse biological macromolecules in solution. It is NOT for soft matter, materials, or systems which are polydisperse.
Registration will be limited to 30 participants in order to allow for data collection and one-on-one and/or small-group interactions between participants and instructors. We will offer 10 participants the opportunity to supply samples for the workshop. These participants will mail in samples for data collection on the BioCAT beamline (Sector 18 at the Advanced Photon Source) before the course. There is no cost associated with the workshop and registration is on a first-come first-served basis.

More information
Course topics:
- Basic principles of SAXS
- Critical sample preparation and data collection procedures, including online size-exclusion chromatography (SEC-SAXS)
- Evaluating data quality
- Basic data processing including size (Rg, Dmax), molecular weight, the P(r) function, and real space reconstructions
- What you need to know for publication
- Overview of several advanced and emerging methods
- Hands-on tutorials with data processing software
While the primary purpose of the course is educational, participants may mail-in a limited number (1-2) of their own research samples for data collection the week before the course.
While BioCAT supports SEC-SAXS, SEC-MALS-SAXS, and batch mode SAXS, due to time constraints students will be limited to only SEC-SAXS data collection. Please read our guide on how to design a SAXS experiment and how to prepare your SAXS samples.
If you have questions, please contact Jesse Hopkins (jhopkins1@iit.edu).
