  "description": "The curve was fitted with a tetramer obtained with CORAL from the unit cell tetrameric structure of the pdb code 1N26 with a Chi-squared-value of 2.49.  Since the experimental MW appeared smaller than a tetramer (confirmed by a not-fitting tetrameric  model) we tried to fit a mixture of tetramer-dimer using OLIGOMER. Two possible dimers were possible: a compact and an extended one. With the compact dimer mixture OLIGOMER estimated a volume fraction of 65% tetramer and 35% dimer and a corresponding Chi-squared-value of 1.92. With the extended dimer mixture OLIGOMER estimated a volume fraction of 47% tetramer and 53% dimer and a improved Chi-squared-value of 1.33.",
