| Abstract: | Ghosts produced from erythrocytes collected from six different cattle were degraded with butanol and pyridine. Of a total of 38 different antigenic determinants available for investigation among the six cows, F, V, J and L were the only specificities detected in the subfractions resulting from either method of degradation. After butanol degradation V, J and L antigens were found in the soluble protein fraction, while F was found in the insoluble protein. Pyridine digestion resulted in all four determinants being detected in the sialoprotein layer, while J was found in the lipoprotein as well. All antigens were relatively weak, being detected in inhibition strengths of 10.0 to 1.25 mg/ml. |
