  • PubMed Abstract: 

    Higher-order structure (HOS) assessment is an important component of biosimilarity evaluations. While established spectroscopic methods are routinely used to characterize structure and evaluate similarity, the addition of X-ray crystallographic analysis to these biophysical methods enables orthogonal elucidation of HOS at higher resolution.
