A simple modification on the vacuum system of the Beckman automated sequencer to improve the efficiency of edman degradation

Academic Article


  • A simple modification of the high-vacuum system of the Beckman automated sequencer is described. The air cylinder controlling the high vacuum to the reaction cup has been replaced with an electrically operated stainless-steel solenoid valve. The system maintains better high vacuum without the necessity for frequent oil changes. The efficiency has been demonstrated by the results of extended amino acid sequence analysis of various unknown proteins and peptides. © 1980.
