The radius of gyration of crotamine is determined by the small angle x-ray scattering technique. Several molecular solutions have been studied to correct for concentration effects. The apparent molecular radius of gyration is also determined as a function of pH. An important change between pH 9.5 and 12.5 is attributed to a dominant effect of molecular aggregation.
