THE MOLECULAR WEIGHT OF ANTIBODIES [PDF]
Journal of Experimental Medicine, 1939 1. Highly purified preparations of homogeneous antibody can be made by the salt dissociation methods (6, 7) without any change in sedimentation due to the method of purification. 2. Antibodies prepared from sera of various animal species fall into two groups as regards molecular weight; in one group cow, horse, and pig, a heavy molecule ...
