Product Information
| Description: | Carboxymethyl cellulose is a carboxymethyl group substitution product of cellulose. Depending on its molecular weight or degree of substitution, it can be a completely soluble or insoluble multimer, the latter of which can be used as a weakly acidic cation exchanger to separate neutral or basic proteins. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
