Abelson and Rawson , using a stepwise elution scheme , fractionated whole sera containing ABO and Rh_antibodies on diethylaminoethyl DEAE_cellulose and carboxymethyl_cellulose .

Speer and coworkers , in a similar study of blood_group antibodies of whole sera , used a series of gradients for elution from DEAE-cellulose .

In the present work whole sera have been fractionated by chromatography on DEAE-cellulose using single gradients similar to those described by Sober and Peterson , and certain chemical and serological properties of the fractions containing antibodies of the ABO and Rh systems have been described .

Serum samples were obtained from normal group A , group B and group O donors .

Three of the anti - Rh sera used were taken from recently sensitized individuals .
