Disposable/reusable size-exclusion chromatography columns packed with a porous matrix that allows unwanted salts and other small molecules to be removed from a sample due to their size. Desalting columns are often used to purify proteins and nucleic acids.
Rapidly desalt protein and biological samples for manual or automated liquid chromatography (LC) with Thermo Scientific Zeba Spin Desalting columns, plates, and cartridges, which enable ≥95% retention of salts and other small molecular contaminants (<1,000 Da).
Thermo Scientific Pierce Dextran Desalting Columns are ready-to-use, disposable, gel-filtration columns for separating proteins and other macromolecules from low molecular-weight buffer salts and reagents.
Pierce 1.8K MWCO Polyacrylamide Desalting Columns are pre-packed with porous polyacrylamide beads and provide for buffer-exchange and desalting of proteins and other macromolecular samples based on a molecular-weight cutoff (MWCO) of 1800.
Desalting and buffer exchange are two of the most widely used applications in resin filtration chromatography. Thermo Scientific Pierce Polyacrylamide Spin Desalting Columns, 7K MWCO (molecular-weight cutoff), are ready-to-use, disposable, gel-filtration columns for the separation of proteins and...
The new and enhanced Thermo Scientific Zeba Spin and Micro Spin Desalting columns and plates are specifically designed for efficient desalting and buffer exchanging proteins with a molecular weight >40 kDa and removing small molecules less than 2 kDa.
Quickly remove non-reacted fluorescent dyes, biotin, reducing agents, and crosslinkers from protein samples with a 7K MWCO in fewer than 15 minutes with Thermo Scientific Pierce Zeba Dye and Biotin Removal columns and filter plates.
