Radiation grafting of a range of monomers allows a diversity of surfac
e characteristics to be generated on a common plastic support. Taken t
ogether with the modular 8-column, 12-row format used with the multipi
n method of peptide synthesis, many thousands of peptides can be gener
ated not only for epitope mapping and other solid-phase applications b
ut also to produce larger quantities of cleaved peptides.
