2D PAGE maps for identified proteins
  • How to interpret a protein map
  • You may obtain an estimated location of the protein on various 2D PAGE maps, provided the whole amino acid sequence is known. The estimation is obtained according to the computed protein's pI and Mw.
  • Warning 1: the displayed region reflects an area around the theoretical pI and molecular weight of the protein and is only provided for the user's information. It should be used with caution, as the experimental and theoretical positions of a protein may differ significantly.
  • Warning 2: the 2D PAGE map is built on demand. This may take some few seconds to be computed.
