    摘要: A protein or peptide is treated by a vapor containing an organic acid represented by the following general formula CF.sub.3 --(CF.sub.2)n--COOH (n is zero or more integer). The resulting reaction mixture is processed by a mass spectrometer to obtain a mass spectrum to measure a mass of respective chemical species contained in the reaction mixture. Alternatively, the reaction mixture is processed by an amino acid analyzer to determine an amino acid sequence of the protein or peptide from the carboxy-terminal. According to another method, the protein or peptide is treated by an anhydride of the organic acid represented by the following general formula CF.sub.3 --(CF.sub.2)n--COOH (n is zero or more integer). The resulting reaction mixture is processed by a mass spectrometer to obtain a mass spectrum to measure a mass of respective chemical species contained in the reaction mixture to determine an amino acid sequence of the protein or peptide from the carboxy-terminal.

    摘要: A method for detecting amino acid derivatives in which 2-anilino-5-thiazolinone derivatives of amino acids are reacted with an amino compound of fluorescein or rhodamine derivative amino compounds to form phenylthiocarbamyl amino acids derivatives. The phenylithiocarbamyl amino acids derivatives are detected with a high level of sensitivity by a fluorescence spectrophotometer.
