What are the advantages of SDS-PAGE electrophoresis?

Advantages of SDS PAGE

• Involves a simple operation that simplifies more complex tasks 
• Enables detection of specific proteins based on mass and characters
• Enables identification of different species based on mass of the protein
• Offers high resolution and advanced separation of protein molecules based solely on mass
• Enables determination of molecular weight of protein in a sample
• Analyzes post-translational modifications
• Is used in peptide-mapping, estimating protein size, identifying purity of proteins, and separating HIV proteins in HIV tests
