Abstract: A medicament is disclosed for reducing the risk of cross-healing (“adhesions”) after surgery. The medicament is a dry powder comprising a surface active phospholipid which is capable of binding to mesothical membranes, and a spreading agent. The medicament is applied as a dry powder to the surgical wound site.

Abstract: A method for the separation of at least one specific binding entity from a mixture of binding entities by the steps of contacting a mixture of binding entities with immobilized peptides in which the peptides specifically bind to the specific binding entities and the peptides contain an amino acid which facilitates removal of the binding entities from the peptides, and separating the immobilized peptide/specific binding entity complexes from the mixture of binding entities. A change in incubation conditions facilitates removal of the binding entities from the immobilized peptides.
