Cultured mouse myeloma cells grow in suspension and synthesize and secrete large amounts of immunoglobulin. Mouse myeloma cells which attach to a plastic substratum have been obtained by mutagenesis and subsequent selection. Normal mouse myeloma cells will also attach to plastic tissue culture dishes pre-treated with poly-L-lysine. The attached cells synthesize and secrete the same large amounts of immunoglobulin as the suspended cells.
