Quaternary Structure Characterisation

Quaternary structure characterisation determines multi-subunit protein assembly affecting therapeutic potency. Native mass spectrometry preserves quaternary structure enabling analysis. Size exclusion chromatography measures oligomeric state. Cross-linking studies identify inter-subunit contacts. Conformational dynamics affect functional assembly.

Regulatory submissions include quaternary structure documentation. Aggregate formation indicates structural instability. Post-approval monitoring confirms structure maintenance. Emerging cryo-EM reveals atomic quaternary details. Manufacturing consistency ensures proper assembly.
