Hemagglutination inhibition by noncorresponding antibodies. Hemagglutination inhibition was performed on several antibodies not corresponding to Gp.Mur antigen, i.e., anti-Le^b, anti-E, anti-D, and anti-S. (A) Visual grading from the conventional tube method. (B) Densitometric-based quantification of hemagglutination. On the X axis are the cell concentrations (cell conc.) of the adsorbing cells (WT-td or 6H-Gp.Mur-6C) and on the Y axis are the signal intensities of the RBC agglutinates.
