的詳細(xì)介紹
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.
-
Unequalled resolution
-
High-efficiency peaks with excellent recovery
-
Higher capacity than other columns based on nonporous particles
-
Useful for characterization and quality control assessment of closely-related protein variants
-
Supports separation of proteins that differ by as little as one amino acid residue
-
Neutral hydrophilic coat that eliminates protein-resin hydrophobic interactions
-
Superior lot-to-lot and column-to-column reproducibility
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.
