Core analytical requirements include: Primary structure confirmation using LC-MS/MS to verify intact mass, sequence integrity and detect modifications Impurity profiling (e.g., sequence variants, degradation products) using high-resolution techniques such as UHPLC-HRMS Aggregation and molecular weight analysis using orthogonal methods like SEC-MALS and sedimentation velocity analytical ultracentrifugation (SV-AUC)
