Structural Biophysics, Niels Bohr Institute Exercise on data analysis of Small-angle scattering data from Bovine Serum Albumin in solution Lise Arleth, Professor Structural Biophysics, Niels Bohr Institute University of Copenhagen, Faculty of Life Sciences 1
Non-trivial structure/shape! Bovine serum albumin M = 66 000 Da Non-trivial structure/shape! 2
Exercise: SAXS analysis of Bovine Serum Albumin (BSA) Use Svergun’s PRIMUS -Plot data -Make background subtractions -Normalize by sample concentration – what do you see? -Make Guinier plots and determine Radius of Gyration for the different concentrations – what do you see? Try to explain -Make Indirect Fourier Transform using GNOM. Discuss. What would be the next steps? Next steps: Kør dammin53qw.exe on 4 mg/ml sample and try to determine the shape.
