• Semi-dry blotting
  • Tank blotting
  • Vacuum blotting

Blotting techniques allow the transfer of proteins and nucleic acids (DNA, RNA) from polyacrylamide or agarose gels onto carrier membranes. Additional these techniques allow immobilization of those components from solutions onto carrier membranes. On the membrane the proteins and nucleic acids offer open access (compared to in-gel techniques) for detection methods for specific molecules (e. g. antibodies).
