Shimadzu, one of the worldwide leading manufacturers of analytical instrumentation, introduces both PPSQ 30A and 33A Edman Sequencer models to the European market. Great demand, proprietary reasons and changes in competitive environment have strengthened Shimadzu\'s decision. Shimadzu has included Edman sequencers in its product program for more than 20 years and, having installed several hundred instruments in Asia, is highly experienced in this product segment.
Edman degradation has been developed by Pehr Edman and is a longstanding established method whereby an amino acid is sequentially cleaved from the N-terminus of a protein, derivatized and separated via HPLC to determine its retention time. By comparing the retention times with those of standard amino acids, the N-terminal sequence can be determined.
