  • Method for purifying and isolating two ionic forms of somatomedin C
    Patent number: 4769361
    Abstract: Two different ionic forms of somatomedin C (pI 6.4-7.0 and pI 8.3-8.6) are separated and isolated by applying an aqueous solution of somatomedin C to a strong cation-exchange column, eluting the somatomedin C from the column by applying a salt concentration gradient at constant pH and recovering the two ionic forms in different eluant fractions.
