Iontosorb CM
Weakly acidic cation exchanger
A weakly acidic cation exchanger based on Bead Cellulose with carboxylic functional groups:
 |
The total volume capacity can be in the range 0.005 - 0.25 mmol/ml, the adequate mass capacity is 0.1 to 1.3 mmol/g dry matter. According to the customer's demands the sorbent volume capacity can be varied in the range given by the mass capacity and water content. The water content of Iontosorb CM moves in the connection with the volume capacity in the range 74 to 89 %.
Iontosorb CM is suitable for chromatographic separations of basic proteins, basic amino acids, peptides, lipids and similar substances. Beside that, it may be used for enzyme immobilization.
Applications
| Column 2 x 8 cm equilibrated with 10 mM Tris-HCl pH 6.0 buffer, containing 10 mM calcium chloride Adsorbed fractions were elued with 1 M NaCl in starting buffer after washing-out the unadsorbed proteins. |
