Human-mouse chimeric monoclonal antibody against human platelet membrane glycoprotein Ib alpha and applications of human-mouse chimeric monoclonal antibody

The invention belongs to the biotechnology field and particularly relates to a chimeric monoclonal antibody which is capable of being combined with high specificity and high affinity of platelet membrane glycoprotein and has an antithrombotic bioactivity and applications of the chimeric monoclonal antibody. The human-mouse chimeric monoclonal antibody against human platelet membrane glycoprotein Ib alpha is characterized by comprising a mouse heavy chain variable region and a mouse light chain variable region, wherein amino acid sequence of the mouse heavy chain variable region is represented as SEQ ID No.1, and amino acid sequence of the mouse light chain variable region is represented as SEQ ID No.2. Immune reactivity of antibody molecules is mainly produced by a constant region, so that the chimeric antibody containing a human constant region is not easy to generate an anti-mouse immune reaction in human bodies. The monoclonal antibody against platelet glycoprotein (GP) Ib alpha is capable of being combined with high specificity and high affinity of human and rhesus monkey platelet membrane glycoprotein Ib alpha (GP Ib alpha), and the antithrombotic effect is achieved.
