Summary Points about Biological SAXS

1. This a structure method that does not require crystals and works with proteins that might be difficult to crystallize (e.g., containing disordered domains).

2. SAXS enables the study of biological macromolecules in a variety of solution conditions ranging from near physiological to highly denaturing.

3. Ab initio structure reconstruction methods enable the making a 3-D molecular envelopes from 1-D scattering data.

4. The modeling of protein:protein and protein:nucleic acid complexes is a valuable application of SAXS. High resolution structures of individual components can be placed inside the SAXS molecular envelope by rigid body fitting.

5. SANS facilitates the study of complexes with one or more deuterated components.

6. Mobile surface loops and domains that move too much to be seen in crystal structures can be visualized by SAXS.

7. Ensembles of partly or fully unfolded proteins or RNAs can be studied by SAXS.

8. The size range for biological SAXS to 5 KDa to 50 MDa.

9. The samples must be aggregate-free (check with dynamic light scattering or multi-angle light scattering). The samples should also be free of interparticle effects.

10. To test for interparticle interactions, scattering data are typically collected at three or four concentrations ranging from 1 to 10 mg/ml. The sample volume per measurement is 30 microliters. Data are collected from a matching buffer sample that should be obtained by dialysis. The interparticle interactions can be weakened by increasing the buffer concentration.

11. Avoid inorganic buffers like phosphate and cacodylate. Use MOPS, MES, or TRIS which scavenge free radicals generated by X-ray damage. 1-5 mM DTT, TCEP, and 2-mercaptoethanol also protect proteins from excessive radiation damage. So does glycerol but you must have a matching concentration in your buffer sample.

12. Take care with detergents. Some detergents scatter X-rays very strongly.

13. Methods of working membrane proteins using SAXS are summarized on pages 313-317 of the following review: Lipfert, J. and Doniach, S. (2007) Small-angle X-ray scattering from RNA, proteins, and protein complexes. Annu. Rev. Biophys. Biomol. Struct. 36, 307-27.

Advantages of Access to a Local Instrument

1. Many samples are stable only for a one week or two after purification. Scheduled time at a beam line has to be arranged a minimum of two weeks in advance for a rapid access program and several months for regular programs.

2. Many samples are to hard transport without freezing. Many samples lack freezing protocols.

3. Many samples need the solution conditions optimized to eliminate aggregation or interparticle effects. There is not much time during a trip to a beam line to optimize solution conditions.

4. Interparticle effects are hard to detect by other methods.

          APS guide to writing a winning beam line proposal

          The APS has a large number of SAXS beam lines with most of them dedicated to materials science. Attending the Beyond Rg Workshop at APS is a good way of becoming familiar with the capabilities of the beam lines as well as by talking to the beam line scientists which is strongly encouraged. Only Biocat beam line 18 is committed to doing bioSAXS and fiber diffraction (Tom Irving ( is the local expert on fiber diffraction). It is currently unique in having liquid chromatography SAXS (LC-SAXS) as an option. The beam line scientist Srinivas Chakravarthy is advocating this technique. The sample volume requirement is 300 microliters with 100 mls of dialysis buffer. The rising and falling shoulders of the peak coming off a 25 ml size exclusion column provide two dilution series and thus lots of data for determining Rg with extrapolation to infinite dilution. It takes an hour to run one sample, but only one sample is required per molecule or molecule* buffer combination. There is a talk of an even smaller SEC column that will enable the collection of data on six samples per hour if they have the sample buffer. The three stations at beam line 12 can be configured to do bioSAXS. 12-ID-C and -D can do time resolved and anomalous SAXS on biological samples. Xiaobing Zuo ( is a beam line scientist at 12-ID-C and -D who has written software for calculating SAXS profiles that is unique in being able to allow the inclusion of heavier atoms in the calculated SAXS profile. This software is unpublished. It is available by writing to him. He also has published a number of papers on SAXS studies of RNA. Beam lines 12 and 18 have time-resolved capabilities with time resolution down to the 20 microsecond scale. One station at ID-5 can do bioSAXS with a flow cell. It requires 250-300 microliter samples per dilution, about 10x the sample requirement of a station with a liquid handling robot. ID-5 is the Dupont-Northwestern-Dow CAT. It has 25% general user access. Steven Weigand at this beam line has co-authored several bioSAXS papers.
