Costimulatory signal(s) in addition to engagement of T cell receptor is important for optimal activation of T lymphocytes. During last decade several dozens of new costimulatory molecules, including 4-1BB, CD40, OX40, CD27, and ICOS, have been identified. It is likely that in Post-Genome Era more molecules with potential costimulatory properties will be brought to our attention. We describe here a simple and reliable strategy for evaluating the functional activities of potential costimulatory molecules using soluble fusion protein between extracellular portion of costimulatory ligand and Fc portion of mouse IgG2a.
