    摘要: In an automated solid-phase peptide synthesizing apparatus comprising at least one reaction vessel containing particulate resin as an insoluble support matrix which anchors elongating peptide chains yielded through coupling-assembly formation of peptide bonds, mixing agitation of reagents, as well as circulation agitation of washing solvents flushing the coupling-associated reaction solutions, introduced in peptide chain-assembly process steps into the reaction vessel, is effected by the bubbling of an inert gas forcibly passed through the reagents or washing solvent via a drainage port of the reaction vessel, in order to promote peptide synthesis. A removable agitation stabilizer is inserted into the reaction vessel as a barrier for inhibiting extra-vessel escape, due to action of the bubbling inert gas, of the reagents as well as the washing solvents, and of the support matrix anchoring the elongating peptide chains. The stabilizer also breaks clumping and coagulative skinning of elongated peptides bound to the support matrix, as effects further consequent of the action of the bubbling inert gas and levitated thereby toward the mouth of the reaction vessel during peptide synthesis. The stabilizer additionally acts as a baffle furthering mixing agitation, to promote dispersive mixing of the peptidyl resin with the reagents and washing solvents during peptide chain assembly; and It also serves to distribute washing solvents evenly along the inner surface of the reaction vessel.

    摘要: In connection with an automated peptide synthesizer, an apparatus and associated method through which peptides produced in simultaneous multiple synthesis are together isolable. Cleavage to liberate the peptides from linkage to the support matrix of the solid phase is carried out in the same vessels in which the synthesizing reactions took place. Prior to cleavage, a drainage port of each reaction vessel is closed off by a cap. The reaction vessel is inserted into a centrifuge tube, which in turn is put into a rack supporting a number of tubes equal to the number of channels of the peptide synthesizing apparatus. After the peptides are cleaved and dissolved into cleaving solution added into each of the reaction vessels, the caps are removed from the drainage ports of each reaction vessel, and the vessel is returned into the centrifuge tube. A plastic jet-fitting attached to the nozzle tip of a blow unit pressure gun is inserted into and pressed into contact against the supply opening of the reaction vessel. Operating a trigger of the pressure gun releases pressurized inert gas into the reaction chamber. The peptide-dissolved cleaving solution is thereby passed through the drainage port, and is thus transferred in liquid phase into the centrifuge tube as filtrate. Associated with the blow unit pressure gun, a needle tube fitting is provided for localized desiccation of wetted peptide following precipitation and centrifuging.

    摘要: The present invention relates to a method for peptide C-terminal fragment sequence analysis, in which the fragment collection is carried out on an allylamine group-derivatized polymer membrane or on allylamine group-derivatized glass fiber filter paper; the collected C-terminal fragment is immobilized thereon using a water-soluble carbodiimide etc.; and the obtained immobilized product is subjected directly to amino acid sequence analysis. The present invention also relates to an apparatus for collecting a peptide fragment. According to the method of the present invention, peptides which are rich in hydrophobic groups in their C-terminus and are therefore difficult to trap with polyvalent ion carriers, currently used in the gas-phase sequencer, can be completely analyzed up to their C-terminus. Also, amino acid sequence analysis can be made even when the amount of C-terminal fragments is very small. In addition, since collection and immobilization of fragments can be done in the same bottle, the risks of contamination and mechanical loss are very low.

    摘要: The present invention relates to an apparatus for collecting a peptide fragment, wherein a C-terminal peptide fragment is collected from a peptide fragment mixture resulting from specific cleavage of the peptide bond between a lysine residue and the C-terminal amino acid residue adjacent thereto. The apparatus has an immobilizing means, a cleaving means, a recovering means and a control means. According to the present invention, since the control means sequentially executes the immobilizing means, cleaving means and recovering means, no skillful work is required in peptide fragment collection, making it possible to collect the carboxyl-terminal peptide fragment with simple operation and high reproducibility.

    摘要: Disclosed is an antioxidant which can exhibit a higher antioxidant ability than known antioxidative peptides. The antioxidant according to the present invention comprises mimosine and/or a mimosine-containing peptide(s). The mimosine-containing peptide is a peptide which comprises at least one mimosine residue in its amino acid sequence. Mimosine has stronger antioxidant potency than known antioxidative tripeptides even when used as it is alone, and therefore is useful as an antioxidant. In addition, the antioxidant action of a peptide can be increased by introducing mimosine thereinto, thereby obtaining a peptide with higher antioxidant potency than the original one.

    摘要: The present invention is directed to a compound represented by the following formula (I), ##STR1## and a linker for peptide synthesis using the above compound. When the linker of the present invention is used for the solid-phase peptide synthesis, it is possible to synthesize those peptides which are sensitive to acid and difficult to synthesize by conventional methods. Also, side reactions can be prevented, and the desired product is produced at a high purity because cleavage can be achieved under milder conditions or in shorter times. In other words, efficient peptide synthesis is possible.
