Protein Characterization
     
Quality controls commonly proposed are:

• SDS-PAGE
• IEF
• Western-Blot
• HPLC
• mass spectrometry
• peptide mapping
• N-terminal sequencing
• endotoxin level
• ELISA
• Bradford assay
• bioassay
• circular dichroism
• analytical ultracentrifugation
• Surface Plasmon Resonance (Biacore)
• isotyping (ELISA)
• N-Glycan profiling
