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.

To enable accurate analysis of a base sequence even in an electrophoretic pattern containing a degraded part. The base sequence of a nucleic acid is determined by conducting the following steps (A) to (C) in this order: (A) a basic peak extracting step wherein basic peaks are extracted from electrophoretic data involving the respective peaks of the four bases obtained by electrophoresing a sample nucleic acid; (B) a condition determining step wherein a basic peak at the search starting point, from which the search is started, and a standard peak-to-peak distance are determined based on the time-series data composed of the basic peaks extracted above; and (C) a base sequence determining step wherein peak-to-peak intervals are successively scanned forward and backward in the above-described time-series data starting from the basic peak at the search starting point and then the peak-to-peak distance is compared with the standard peak-to-peak distance as determined above so as to add an interpolation peak to a peak-missing area.
摘要:
Disclosed herein is a method for assessing the degree of reliability of a nucleic acid base sequence, by which a higher-accuracy assessment result of the degree of reliability can be obtained as compared to a case where the degree of reliability is assessed based on only the evaluation of analytical data. The method includes the steps: (A) when measured data is processed into analytical data, computing a processing evaluation value E1i for evaluating quality of measured data of an i-th base and contents of processing having been performed on the measured data of the i-th base; (B) computing an analytical data evaluation value E2i of the i-th base based on the processed analytical data; and (C) computing a degree of reliability by a predetermined calculation formula using the processing evaluation value E1i and the analytical data evaluation value E2i.

An electrode plate of a sample plate is set on the body of an electrophoretic apparatus, while a plug is inserted into a migration high voltage line connection hole and connected to a high-tension distribution cable. Each well of a base plate is inserted into a through hole of a well guide and further press-fit and engaged into a cavity of an electrode plate, for fixing the base plate to the electrode plate. Thereafter a sample is introduced into each well of the base plate and an end of a capillary column is dipped into each well for applying a migration voltage and electrophoretically injecting the sample into the capillary column.
