摘要: An reaction vessel 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 and positioned within a reaction chamber. Edman reagent is applied to the sample to effect amino acid sequence analysis of protein or peptide from amino-terminal. By such construction, reaction efficiency is increased to produce sequentially thiazolinon amino-acid derivatives to thereby increase number of identified remaining amino acids, thereby enabling microanalysis of sample.

摘要: To easily detect an amino acid derivative with high sensitivity in carrying out amino acid sequence analysis of a protein from an amino terminal, 2-anilino-5-thiazolinone amino acid derivative is reacted with a volatile primary amine represented by the general formula X-NH.sub.2, wherein X denotes a hydrocarbon containing a halogen to form a phenylthiocarbamyl amino acid derivative, and the phenylthiocarbamyl amino acid derivative is detected by using a gas chromatograph provided with an ECD. Accordingly, amino acid sequencing may be performed with high sensitivity without the need to use harmful radioisotope labeled or fluorescent amino compounds.
