美国戴安Dionex ProPac SAX ａnd WAX Protein Column 生物色谱柱
High-Resolution, Strong ａnd Weak Anion-Exchange Columns for the Separation of Proteins
The ProPac® SAX-10 is a nonporous, strong anion-exchange column （quaternary amine functional group）. The ProPac WAX-10 column is a weak anion exchanger （tertiary amine functional group）. Both are based on a nonporous core particle that provides pressure stability. A hydrophilic layer prevents unwanted secondary interactions ａnd a grafted anion exchange surface provides pH control, selectivity, ａnd fast mass transfer for high efficiency separation, as well as moderate capacity.
ProPac SAX-10 ａnd WAX-10 columns can resolve protein isoforms that differ by as little as one charged residue. Differences in selectivity between the WAX-10 ａnd SAX-10 provide flexibility in maximizing resolution of closely related species.
All ProPac columns are manufactured ａnd tested under the strictest specifications, resulting in unmatched column-to-column ａnd lot-to-lot reproducibility. Dionex also offers these columns as lot ｓelect packages, containing three columns from one lot or three columns from three different lots, to assist quality control scientists in method validation.
