[Monoclonal antibodies to the human group-specific antigen]

Serologic description of murine monoclonal antibodies (H-86/44 and H-86/50) which are capable to detect a membrane-connected form of human H antigen is given. The antibodies are notable for ability (H-86/44) to be absorbed by salivary H substance of ABH secretors i.e. to detect a soluble form of H antigen. Highly specific, highly active and standard anti-H reagents may be produced on the basis of the anti-H monoclonal antibodies obtained.
