Cat.no: G-15-001D
Product Overview: Dextran is a gel filtration medium prepared by crosslinking dextran with epichlorohydrin. Dextran G-15 is well established gel filtration medium for desalting and buffer exchange of peptides and small biomolecules >1 500 molecular weight.
Characteristics: 1. Quickly desalts, removes contaminants and transfers to a new buffer in a single step.2. Suitable for buffer exchange and cleanup of biological samples, for example peptides, small proteins, and oligosaccharides larger than 1500 molecular weight3. Efficient removal of contaminants such as salts, dyes, and radioactive labels
Size: 100 g
Matrix: Cross-linked dextran
Average particle size: particle wet: 60 μm-180 μmparticle dry: 40 μm-120 μm
Recommended flow rate: 20-47 cm/h
Chemical stability: Dextran is stable in all commonly used aqueous buffers and additives such as ionic and non-ionic detergents, denaturing agents (8 M urea or 6 M guanidine hydrochloride). The media are stable in short chain alcohols such as ethanol, methanol and propanol, but concentrations above 25% should not normally be used. Note that Dextran shrinks in alcohol solutions.
pH working range: 2-13
Warning: Avoid changes in temperature which may cause air bubbles in the packing.
