MONOCLONAL ANTIBODY AGAINST ENDOTHELIN, HYBRIDOMA CAPABLE OF PRODUCING THE SAME AND RADIOIMMUNOASSAY FOR ENDOTHELIN BY USING THE SAME.

摘要

A monoclonal antibody against endothelin having the association constant Ka not less than 1 X 10<1><0>M<-><1>, a hybridoma capable of producing the same and a radioimmunoassay for endothelin, which is characterized by using the same. In accordance with the monoclonal antibody, the hybridoma and the radioimmunoassay of the present invention, endothelin can be selectively determined with high precision.
