Many structural genomics (SG) programmes rely on the design of soluble protein domains. The production and screening of large libraries to experimentally select these soluble protein-encoding constructs are limited by the technologies and efforts that can be devoted to a single target. Using basic technologies available in any laboratory, a method named `boundary shuffling' was devised to generate orientated libraries for soluble domain selection without impeding the target flow.
Keywords: boundary shuffling; soluble protein domains.
