Abstract
A method of stabilizing .beta.-galactosidase peptide fragments against storage degradation for use in a complementation assay which comprises storing the peptide fragment in a storage medium containing an ionic surfactant or a surfactant derived from a sugar residue and adding a cyclodextrin to the storage medium after storing the peptide fragments but before using them in a complementation assay.
