The Journal of Peptide Science is a cooperative venture of John Wiley & Sons Ltd and the European Peptide Society undertaken for the advancement of international peptide science by the publication of original research results and reviews. Two types of original article are accepted full papers and rapid communications. Full papers which make up the greater part of the Journal are definitive reports on substantial experimental (or occasionally theoretical) investigations in the field which have reached maturity. They are of the traditional kind comprising discussion and evaluation of the results at appropriate length together with experimental detail. If deemed necessary by the Editors full papers will be treated as accelerated publications. Rapid communications of two to four printed pages are either preliminary reports of important work meriting urgent publication or concise definitive reports on specific points. Reviews are usually by invitation but we shall welcome suggestions from anyone and especially offers from potential contributors who should contact the Editor-in-Chief or one of the Editors before starting work. The scope of the Journal embraces the whole range of peptide chemistry and biology: the isolation characterisation synthesis properties (chemical physical conformational pharmacological endocrine and immunological) and applications of natural peptides; studies of their analogues including peptidomimetics; peptide antibiotics and other peptide-derived complex natural products; peptide and peptide-related drug design and development; peptide materials science; combinatorial peptide research; the chemical sysnthesis of proteins; and methodological advances in all these areas. The spectrum of interests is well illustrated by the published Proceedings of the regular international Symposia of the European American and Japanese Peptide Societies.
