A hybridoma obtainable by fusing a spleen cell or lymphocyte of an animal immunized by a complex of a surfactant compound for synthetic detergent and protein with a myeloma cell, which produces a monoclonal antibody against the compound or its degradation product. A monoclonal antibody against a surfactant compound for synthetic detergent or its degradation product which is produced by the hybridoma, a kit for immunoassay of detergent, its degradation product or a mixture thereof containing as an essential constitutional component the monoclonal antibody, and an immunoassay method, in particular, ELISA of detergent, its degradation product or a mixture thereof in a specimen by reacting the specimen with the monoclonal antibody supported on a carrier and the detergent, its degradation product or the mixture thereof labeled with a labeling agent are also disclosed.
