[Biological properties of a synthetic sequence (10-24) of the gamma chain from sub-unit A of cholera toxin].

Abstract

The biological activity of a synthetic fragment of choleric toxin. gamma Chain A subunit, was studied in vivo. This pentadecapeptide (10-24) was synthesized by solid phase method and finally purified by HPLC. Associated with the B subunit, the peptide inhibits the tissue water loss induced by commercial choleric toxin.
