Western Blot

Uses antibodies to accurately detect and measure specific proteins in biological samples.


  • Highly specific for a particular protein
  • Detects antigen as a protein, rather than peptides
  • Can confirm presence and quantity of a specific protein
  • Minimal sample processing necessary in most cases


  • Must have a known target protein
  • Some detergents may interfere
  • Not cost effective for very small sample sizes
