Use of superparamagnetic beads for the isolation of a peptide with specificity to cymbidium mosaic virus.

A modified method for the rapid isolation of specific ligands to whole virus particles is described. Biopanning against cymbidium mosaic virus was carried out with a commercial 12-mer random peptide display library. A solution phase panning method was devised using streptavidin-coated superparamagnetic beads.
