Abstract
An instrument and method for accelerating the solid phase synthesis of peptides are disclosed. The method includes the steps of deprotecting a protected first amino acid linked to a solid phase resin by admixing the protected linked acid with a deprotecting solution in a microwave transparent vessel while irradiating the admixed acid and solution with microwaves, activating a second amino acid, coupling the second amino acid to the first acid while irradiating the composition in the same vessel with microwaves, and cleaving the linked peptide from the solid phase resin by admixing the linked peptide with a cleaving composition in the same vessel while irradiating the composition with microwaves.
Claims3
An instrument for microwave assisted solid phase peptide synthesis (SPPS) comprising:
- a magnetron;
- a cavity that supports a single mode at frequencies produced by said magnetron;
- a microwave transparent vessel in said cavity;
- a source of inert gas for agitating SPPS compositions in said cavity;
- a passageway in communication with said inert gas source and said vessel;
- a plurality of amino acid containers;
- at least one passageway between said amino acid containers and said vessel;
- and
- a processor that controls the addition of amino acids to said vessel at appropriate points in an SPPS synthesis.
