The invention provides a hybridoma cell line 1C11 and an anti-aflatoxin general monoclonal antibody secreted by the same as well as the applications thereof. The hybridoma cell line 1C11 can be used for preparing a high-titer aflatoxin antibody, and a mouse hydroperitoneum antibody is measured to reach 5.12*106 by using an ELISA (Enzyme-Linked Immunosorbent Assay). The anti-aflatoxin general monoclonal antibody has high sensitivity, respectively reaches the IC50 (50% inhibiting concentration) of aflatoxin B1, B2, G1 and G2 to be 1.2, 1.3, 2.2 and 18.0 pg/mL, is the antibody with highest sensitivity among currently reported four aflatoxin antibodies, is used for measuring the total aflatoxin amounts, i.e. the total amounts of the aflatoxin B1, B2, G1 and G2 and has great practical application values.
