Abstract
A reaction chamber utilizes a sample carrier composed of a magnetic core and a surface coating effective to support sample of protein or peptide. The sample carrier is floated magnetically by means of electromagnets positioned within a reaction vessel. Edman reagnet is applied to the sample to effect amino acid sequence analysis of protein or peptide from amino-terminal. By such construction, reaction efficiency of repeated production of thiazolinon amino-acid derivatives is increased so as to increase number of identified amino acids, thereby enabling microanalysis of sample.
