Abstract
1. A method is described for the isolation of certain of the α1-globulins of rat plasma that are known to increase in concentration after tissue damage (acute-phase globulins). 2. Although apparently homogeneous when examined by disc electrophoresis at pH9, these proteins could be subdivided further by isoelectric fractionation. 3. Treatment with neuraminidase removed approx. 60% of the sialic acid originally present in these proteins and gave almost completely homogeneous material of decreased mobility when examined by disc electrophoresis in polyacrylamide gel. When subjected to immunoelectrophoresis this material gave a single arc. 4. The homogeneity of the isolated materials was examined by ultracentrifugation. The single peak thus found is consistent with molecular weights of 45000–46000. 5. The isolated materials were shown to be glycoproteins containing approx. 15% of carbohydrate, and to have isoelectric points in the range pH4·4–4·8.Keywords
