ABSTRACT:
An apparatus is provided for automatically constructing a polypeptide of high purity, up to 50 amino acids in length, using only single couplings. The apparatus includes an activation system for receiving protected amino acids, one kind at a time, having a common vessel (an activator vessel) in which to activate each of the amino acids. Also included is a reaction vessel for containing a resin used in solid-phase peptide synthesis for attaching a peptide chain thereto. A transfer system is also provided, which operates under control of a computer, to transfer the activated species from the activation system to the reaction vessel and to transfer amino acids, reagents, gases, and solvents from one part of the apparatus to another. The activator system also includes a temperature controlled concentrator vessel in which an activator solvent is replaced by a coupling solvent to enhance the coupling of the activated species to the peptide chain in the reaction vessel. Also included in the synthesizer system is a vortexer for affecting total washing of materials in the reaction vessel and the reaction vessel itself, an automated peptide resin sampling system, and an autodelivery system for providing individual containers of amino acid to the synthesizer in the order desired in the peptide sequence. A liquid sensor system is also included to monitor transitions between gases and liquids in specific tubes in the synthesizer in order to provide input signals to the computer system for control purposes. The computer system software which controls the operation of the synthesizer is organized according to a series of menus which allows the user of the system to select individual cycles of operation for each vessel in the synthesizer. In addition, an algorithm has been developed which provides for optimum efficiency in the production of a peptide for any given selection of cycles.
