    • A process and apparatus for the conversion of anilinothiazolino amino acid derivatives of peptides and proteins for use with conventional sequencers in the overall Edman degradation process. The apparatus comprises a modular unit separate from the sequencer having an independently programmable control and flow actuating and directing means including a source of pressurized nitrogen, a conversion reagent container, a wash solvent container, a reaction vessel, and a plurality of interconnecting tubes and valves controlled so as to regulate the amounts and durations of all fluids entering and leaving said reaction vessel under gas pressure.The process comprises performing the steps of conversion, sample recovery, drying and washing at temperatures below but near to the respective boiling points of both the reagent and the solvent, and under reflux tower conditions. A specific embodiment employs anhydrous methanolic hydrogen chloride for the reagent and dichloroethane methanol (7:3) for the solvent, and both the conversion and the washing are done at 65.degree. C., in a reaction vessel comprising a lower, heated portion, and an upper, cooled portion where the reflux action takes place both during the conversion and washing steps.
    • 用于在总体Edman降解过程中用于与常规测序仪一起使用的肽和蛋白质的苯酰噻唑啉氨基酸衍生物的方法和装置。 该装置包括与定序器分离的模块化单元,其具有独立可编程控制和流动致动和引导装置,其包括加压氮源,转换试剂容器,洗涤溶剂容器,反应容器和多个互连管和阀 控制以调节在气体压力下进入和离开所述反应容器的所有流体的量和持续时间。
