Method of Making a Pharmaceutical Composition Comprising a p80 Protein

Abstract

Present invention relates to a method of making a recombinant p80 polypeptide using an E. coli culture comprising a plurality of E. coli host cells each transformed or transfected with an expression vector containing a DNA fragment encoding a recombinant p80 polypeptide; and inducing the E. coli culture by adding a 0.2% L-Arabinose. The isolated, recombinant p80 is added to a pharmaceutical composition, wherein it binds to a therapeutic agent comprising one or more of: drugs, dyes, small molecules, biomolecules, proteins or a combination thereof. The p80 polypeptide enhances the transportation of the therapeutic agent into the bloodstream by the p80 functioning as a tight junction modulator to enhance the permeability of the intestinal epithelium to the therapeutic agent.
