PD MidiTrap G-10 columns are prepacked, single-use gravity columns for buffer exchange and cleanup of biological samples, for example peptides, small proteins, and oligosaccharides.

• Easy cleanup of peptides, small proteins, or carbohydrates larger than Mr 700, before downstream analysis such as liquid chromatography, electrophoresis, and MS
• Efficient removal of contaminants such as salts, dyes, and radioactive labels
• High desalting capacity
• Preparation of samples in the volume range 400 to 1000 μl

PD MidiTrap G-10 gravity columns give fast and simple desalting and buffer exchange without any need for a purification system, PD MiniTrap G-10 columns are prepacked and designed for rapid, convenient sample clean-up of small proteins, peptides, oligo-saccharides and other small biomolecules (>700 Mr).

For smaller scale please use PD MiniTrap G-10 columns (300 μl).
