Abstract: | Synthesis of the IgG-binding factor was estimated by the amount of labeled [14C]hydrolysate of proteins in the total synthesized de novo protein. The obtained data showed that the IgG binding factor which was synthesized by blood lymphocytes of the normal cattle and that suffered from chronic leukemia had a molecular weight of 72 kDa and was revealed before and after restoration of S-S bonds as one peptide. |
