An apparatus for simultaneous manual solid-phase synthesis of multiple peptide analogs.

A new design of reaction vessel for simultaneous manual solid-phase synthesis of multiple peptide analogs is described. Simultaneous use of four of these vessels attached to a single rotary mixer has been successfully applied to synthesis of two sets of four decapeptide amide analogs. Efficient coupling was indicated by chemical determination at the end of each synthesis cycle and overall final yields of between 78 and 84% were obtained. The products obtained were of a high quality, as assessed by high-performance liquid chromatography and amino acid analysis. This system allows expeditious synthesis of multiple peptide analogs for structure-function studies with economical use of efficiently ventilated laboratory space.
