ABSTRACT:
A novel natural killer cell-specific molecule, designated as PEN5, consisting essentially of a glycoprotein pair called PEN5.alpha. and PEN5.beta., having apparent molecular weights of 120-150 and 210-245 kdal, respectively. Monoclonal antibodies, including immunoreactive fragments and derivatives thereof, that bind to unique epitopes present on this NK cell-specific molecule; hybridomas that produce the monoclonal antibodies; methods of using the antibodies and fragments and derivatives; and methods for detecting and/or removing natural killer cells from a sample containing a mixed population of cells are also provided.
