Cut and combine: An easy membrane-supported combinatorial synthesis technique

A combinatorial synthesis process involving sequential cycles of cutting a membrane support into pieces and combining these into groups and subjecting the groups to simultaneous solid-phase chemical reactions is demonstrated by the rapid assembly of four hundred N-terminally biotinylated, soluble, octameric peptide pools. Index patterns printed onto the synthesis membrane allowed a direct identification of the compounds. These were used to study protein kinase substrate selection in a parallel microplate adapted P-32-phosphorylation assay with subsequent spotting on a biotin-capture membrane, (C) 1998 Elsevier Science Ltd.
