An antigen and antibodies prepared based on peptidylarginine deiminase (PADI4) serving as a tumor marker, and application thereof are disclosed. The antigen has an amino acid sequence shown as SEQ ID NO.1. Specific antibodies prepared by using the antigen are also disclosed. The protein PADI4 monoclonal antibodies include a protein PADI4 monoclonal antibody coated onto an ELISA plate and a biotin-labeled protein PADI4 monoclonal antibody. A kit prepared by using the antibodies of the present disclosure can effectively and stably determine a protein PADI4 level of a human serum, and has a broad spectrum, detectability, and high test repeatability. |
