Method to Produce Monoclonal Antibodies to Human T-Cell Receptor Elements
Tech ID: 91-02
Summary - The specificity of T-cell receptor to an antigen is determined by the five variable elements of the a and ß chains. Research scientists at National Jewish Health have developed a method to produce monoclonal antibodies against any of the five variable elements of human T-cell receptor. This method relies on the transfection of human/mouse hybrid T-cell receptor a or ß chains genes into a mouse T-cell hybridoma lacking an endogenous a or b chain gene.
Potential Applications
- Research reagents.
- Monoclonal antibodies for therapeutic use.
Advantages of Invention
- Simple method
- Method adaptable to any of the five variable elements of the human T-cell receptor.
State of Development - Scientists have demonstrated that using this method:
- hVß elements can be expressed on the surface of mouse T-cell hybridomas.
- The transfected T-cell hybrids are excellent immunogens in mice for hVß.
- Monoclonal antibodies against hVß13.1 and -13.2 can be raised and be used for the measurements of Vß13.1 and -13.2 in humans.
