POLYPEPTIDES HAVING A TRIGGERING NK ACTIVITY AND BIOLOGICAL APPLICATIONS

摘要

The invention relates to polypeptides having a triggering NK activity and an aminoacid sequence that is at least 80 identical over its entire length to the polypeptide having SEQ ID N DEG 1, and any immunogenic fragments thereof, as well as to the polyclonal and monoclonal antibodies directed against said polypeptides, and immuno-reactive fragments thereof. Application for detecting NK cells in a sample, for their removal from a sample or for enrichment of NK cells, and for NK cell natural cytotokicity regulation.
