| abstract |
The invention discloses a mouse anti-human IgG monoclonal antibody, which has the amino acid sequences of heavy chain variable region CDR1, CDR2 and CDR3 shown in SEQ ID NO.26, 28 and 30, and the amino acid sequences of light chain variable region CDR1, CDR2 and CDR3 shown in SEQ ID NO.42, 44 and 46. The invention also provides a nucleic acid molecule for encoding the monoclonal antibody, an expression vector containing the nucleic acid molecule and a host cell. The monoclonal antibody of the invention has higher sensitivity and specificity when being applied to immunoassay. |
