High-performance centrifuge desalting columns, microplates and cartridges, as well as traditional gravity-flow columns containing gel-filtration resins for efficient buffer-exchange of protein samples by size-exclusion chromatography.
Remove contaminants such as small peptides and crosslinking reagents from sample volumes ranging from 2µl to 4 ml with Zeba, 40K MWCO, Spin Desalting Columns
The effective removal of salt and small molecules from samples is a critical step in identifying and quantifying large number of proteins in biological systems.
Dextran Desalting Columns (5,000 MWCO), are pre-packed with cross-linked dextran. The wet bead diameter is 50-150 µm. The gel has good rigidity for easy handling and excellent flow properties.
Excellulose desalting resin is extremely stable to heat, freeze-thaw cycles, organic solvents and acidic or basic conditions. It also demonstrates excellent mechanical stability and offers excellent sample recoveries as a result of the slower flow rate.
Polyacrylamide Desalting Columns are pre-packed with porous polyacrylamide beads. The Polyacrylamide gel is not subject to enzymatic degradation and will not serve as a nutrient for microbial growth.
