Introduction
The Thermo Scientific™ Zeba™ Spin Desalting Columns contain a high-performance resin that offers exceptional desalting
or buffer-exchange for protein samples. Samples volumes between 2µL-4mL and containing as low as 20µg of protein/mL
can be processed with unsurpassed protein recovery and ≥ 95% retention of salts and other small molecules (< 1000Da).
These columns require no chromatography system. The spin-column method eliminates waiting for samples to emerge by
gravity flow and the subsequent monitoring of fractions for protein recovery.
Important Product Information
• The Zeba Spin Desalting Columns and Plates contain a size-exclusion chromatographic resin to separate proteins from
small molecules. As with all size exclusion-based separation, the amount of small molecule removed and protein
recovered are affected by the nature of the molecules and volume of sample. The sample volumes recommended provide
exceptional removal of a variety of small molecules (typically > 95% for molecules < 1000Da); however, proteins and
small molecules often behave differently than predicted because of a variety of factors such as hydrophobicity,
secondary structure and interactions. Therefore, some optimization of sample volume might be required to achieve
optimal performance for each specific sample. In general, reducing the sample volume added to the column increases
small molecule removal, and increasing sample volume maximizes protein recovery.
• Also available are Zeba Spin Desalting Columns and Plates with a 40K MWCO, which enable removal of salts and other
small molecules < 2000Da and recovery of proteins and other macromolecules > 40,000Da.
