The Thermo Scientific™ Zeba™ Spin Desalting Plates (40K MWCO) are high-throughput, centrifuge-compatible tools for rapid desalting and buffer exchange of protein samples. Designed specifically for macromolecules larger than 40 kDa, these 96-well filter plates remove small contaminants (<2 kDa) such as salts, dyes, excess labels, and crosslinkers from small-volume samples ranging from 20 to 100 µL.
Each well is pre-packed with a proprietary, high-efficiency size-exclusion resin that offers superior protein recovery while withstanding centrifugal force without bead deformation. These plates are ready to use—no hydration or resin packing required—making them ideal for processing multiple protein samples simultaneously in proteomics, antibody purification, enzyme assays, and biochemical research workflows.
Key Features & Benefits
-
High Molecular Weight Cut-Off (40K MWCO)
Effectively separates proteins and macromolecules (>40 kDa) from low molecular weight contaminants (<2 kDa). -
High Recovery, Even at Low Concentrations
Optimized resin formulation minimizes protein loss and maximizes desalting efficiency. -
Fast and Efficient Workflow
Complete desalting in 5 minutes without the need for dilution, fraction collection, or complex equipment. -
Flexible Throughput
Available in 2- and 4-plate packs; ideal for labs requiring reliable, repeatable results with small sample volumes. -
Pre-packed and Ready-to-Use
Eliminates the time and variability associated with manual plate preparation. -
Compatible with Standard Centrifuges
Designed for use in common laboratory plate rotors.
Applications
- Buffer exchange prior to mass spectrometry, ELISA, HPLC, or electrophoresis
- Removal of detergents, dyes, salts, and excess chemical reagents after labeling or conjugation
- Desalting of antibodies, enzymes, recombinant proteins, or protein complexes
- Sample cleanup before protein interaction studies or functional assays
- High-throughput preparation of protein samples in drug discovery and biotechnology research
