Beschreibung
Zusammenfassung:	A method of producing rat monoclonal antibodies to human T-cell lymphocyte antigen epitopes other than those epitopes defined by murine monoclonal antibodies directed to the same antigen comprising: (1) immunizing a rat or rat immunocompetent cells in vitro with an immunogenic amount of an antigen comprising T-cell lymphocyte markers; (2) fusing immunized cells from said rat or immunized rat immunocompetent cells with immunocytoma cells; (3) selecting hybridoma cells that produce antibody that binds to the human T-cell lymphocyte antigen epitopes other than those epitopes defined by murine monoclonal antibodies directed to the same antigen; (4) culturing the selected hybridoma cells; and (5) recovering said antibody. A method of producing rat monoclonal antibodies that bind to human CD4 antigen, the method comprising: (1) immunizing a rat or rat immunocompetent cells in vitro with an immunogenic amount of an antigen comprising CD4 molecule; (2) fusing immunized cells from said rat or immunized rat immunocompetent cells with immunocytoma cells; (3) selecting hybridoma cells that produce antibody that binds to human CD4 antigen; (4) culturing the selected hybridoma cells; and (5) recovering said antibody. A hybridoma that produces a rat monoclonal antibody that binds to human CD4 antigen. A rat monoclonal antibody that binds to human CD4 antigen. In a preferred embodiment the rat monoclonal antibody binds to a human CD4 antigen epitope other than those epitopes defined by murine monoclonal antibodies OKT4 and Leu3a. A rat monoclonal antibody that binds to human T-cell lymphocyte antigen epitopes other than those epitopes defined by murine monoclonal antibodies directed to the same antigen.
