Peptide and protein preservation method

A method for preserving or storing tagged peptides or proteins by means of their reversible binding to solid or semi-solid derivatized matrices, said method comprising:

• (a) passing a fluid or solution that contains the tagged peptide or protein through a solid or semi-solid porous matrix having functional groups, wherein the tag of the peptide or protein binds by affinity to functional groups that are present in the matrix,
• (b) passing a cleaning solution through the matrix to eliminate biological material, peptides or proteins, or other substances of the fluid or solution not bound to the solid or semi-solid derivatized, porous matrix,
• (c) partially or totally drying the matrix comprising the tagged peptide or protein at moderate temperature from 12° to 60° C.
• (d) placing the partially or totally dried matrix comprising the tagged peptide or protein inside a wrapping that is clean and septic during the time required prior to its user, and
• (e) recovering the tagged peptide or protein from the matrix by passing a solution through the matrix that comprises specific compounds that interrupt the affinity binding between the peptide or protein tag and the functional groups of the solid or semi-solid porous matrix.
