    Abstract: Respective monoclonal antibodies are fixed into respective wells of a microplate one by one, and bonded with labeled analogs of PTH amino acid derivatives. A solution containing PTH amino acid derivatives obtained by Edman degradation is dripped on to the microplate for causing competitive reaction to the monoclonal antibodies with the analogs, and thereafter non-bonded PTH amino acid derivatives and liberated analogs are washed out. Then enzyme-labeled antibodies against the analogs are added and the quantity of bonded enzyme-labeled antibodies is measured thereby determining the types and quantities of the PTH amino acid derivatives. Constitutive amino acid can be detected in high sensitivity.

    Abstract: The present invention provides a novel internal standard for amino acid sequencing which contains a peptide consisting of unnatural amino acid residues, such as ornithine, norvaline, norleucine and .alpha.-aminobutyric acid, that is capable of being sequenced simultaneously with an unknown peptide or protein without interfering with the analysis. The internal standard peptide has an amino acid sequence containing at least two different unnatural amino acid residues having retention times distinct from the corresponding retention times for natural amino acid residues. Information derived from the sequencing of the internal standard allows determination of repetitive yield, lag, N-terminal blockage and discrimination between blank cycles caused by missed injection and blank cycles caused by faulty delivery of chemicals during the sequencer reactions. The present invention further provides novel synthetic control peptides containing from about 3 to 100 natural amino acid residues that are designed for use in monitoring the proper operation of amino acid sequencers and to monitor peptide or protein cleavage reactions. The control peptide, or mixture of control peptides, are designed to obtain data for many or all common, uncommon and difficult to measure amino acids within 15 sequencer cycles and to provide cleavage sites for at least 4 different amino acid cleavage reactants.

    Abstract: A novel reactor for reacting and subsequently analyzing sub-picomole quantities of a sample organic molecule. The reactor includes a continuous capillary connected between two valves that control fluid flow in the capillary. One part of the capillary forms a reaction chamber where the sample may be immobilized for subsequent reaction with reagents supplied through the valves. Another part of the capillary passes through or terminates in the detector portion of an analyzer such as an electrophoresis apparatus, liquid chromatographic apparatus or mass spectrometer. The apparatus may form a peptide or protein sequencer for carrying out the Edman degradation reaction and analyzing the reaction product produced by the reaction. The protein or peptide sequencer includes a reaction chamber for carrying out coupling and cleavage on a peptide or protein to produce derivatized amino acid residue, a conversion chamber for carrying out conversion and producing a converted amino acid residue and an analyzer for identifying the converted amino acid residue. The reaction chamber may be contained within one arm of a capillary and the conversion chamber is located in another arm of the capillary. An electrophoresis length of capillary is directly capillary coupled to the conversion chamber to allow electrophoresis separation of the converted amino acid residue as it leaves the conversion chamber. Identification of the converted amino acid residue takes place at one end of the electrophoresis length of the capillary.
