	Peptide/MHC tetrameric complexes are engineered molecules which will 
specificaaly bind to antigen specific cells and thus are capable of 
detecting these cells.  For example, gag specific tetramers will tag those 
cells in HIV infected persons which specifically see the gag antigen.  Most 
are MHC I restricted so will label the cytotoxic cells.  The ability to 
resolve the very small percentage of antigen speicific cells is an area of 
great interest.

For a reference try: Altman et al.,  Science 274: 94, 1996.

Tom
