Sandia-Separation of proteins by applying an electric field

  • by

The selective separation of biomolecules such as DNA and proteins through nanopores appears to be a promising technique for characterizing, counting, and sequencing these species. The patent describes a technique that can be used for this purpose, to separate proteins using a specific protein dependent electric field across a nanoporous polymer exclusion membrane. It states that at low electric fields, certain proteins do not pass through the membrane but at… Read More »Sandia-Separation of proteins by applying an electric field
