METHODS FOR THE IDENTIFICATION OF PEPTIDYL COMPOUNDS INTERACTING WITH EXTRACELLULAR TARGET MOLECULES

摘要

The present invention provides libraries expressing peptide libraries on the extracellular cell surface of host cells and methods for identifying peptides that bind extracellular target molecules under the physiological conditions encountered in biological fluids and secretions. The present invention is also directed to vectors for expressing gene fusion proteins and for targeting those fusion proteins to the extracellular cell surface.
