[The carbohydrate component of immunoglobulin G peculiar to malignant growth]

The total amount of carbohydrates and some carbohydrate components was studied in total preparations of immunoglobulins of blood serum of healthy people and cancer patients as well as in immunoglobulin G subfraction peculiar to cancer and in the fraction isolated from immunoglobulin G of healthy people blood serum corresponding to the place of column elution. An insignificant increase is established in the content of carbohydrates in the protein peculiar to cancer as compared to their amount in immunoglobulin G of blood serum from healthy people (1.93 and 1.46 g per 100 g of protein, respectively). A conclusion is drawn that the content of the studied substances in the protein peculiar to cancer cannot determine the peculiarities of its physicochemical, immunological and biological properties.
