Sp2/0-Ag14 Cells

The Sp2/0-Ag14 cell line, commonly referred to as Sp2/0, is a murine myeloma cell line used extensively for the production of monoclonal antibodies. Originating from the BALB/c mouse strain, this cell line was developed by fusing spleen cells from immunized mice with myeloma cells that lack the enzyme hypoxanthine-guanine phosphoribosyltransferase (HGPRT). This deficiency makes Sp2/0 cells unable to survive in HAT (hypoxanthine, aminopterin, thymidine) medium, a feature crucial for hybridoma selection when fused with spleen cells from immunized mice, as only the hybridoma cells can proliferate in this selective medium. The Sp2/0-Ag14 cell line is characterized by its stability and robustness in cell culture, making it a preferred host for hybridoma production. The absence of immunoglobulin production in these cells is a critical feature because it prevents the secretion of endogenous immunoglobulins that could interfere with the monoclonal antibody produced by the hybridomas. This cell line has been extensively used in scientific research and industrial applications for generating monoclonal antibodies against a wide array of antigens. The antibodies produced are used in research, diagnostics, and therapeutic applications, highlighting the significant utility of the Sp2/0 cell line in biotechnological and pharmaceutical industries.
