Description

General description

Sephadex® G-25 is well established gel filtration medium for desalting and buffer exchange in industrial applications.

Sephadex® is a gel filtration medium prepared by crosslinking dextran with epichlorohydrin. Different types of Sephadex® differ in their degree of cross-linking and hence in their degree of swelling and their molecular fractionation range. Sephadex® G-25 is one of five different G-types ranging from G-10 for small molecules to G-75 for larger molecules. Sephadex® G-25 is available in 4 different particle sizes (Course, Medium, Fine & Superfine).

Sephadex® G-25 is available in different bulk pack sizes and convenient pre-packed formats.
As a BioProcess medium, Sephadex® G-25, meets industrial demands with security of supply and comprehensive technical and regulatory support.

Features and Benefits

• Quickly desalts, removes contaminants and transfers to a new buffer in a single step.
• Excellent recovery and minimum sample dilution
• Available in prepacked HiPrep Desalting and HiTrap® Desalting columns for fast and convenient desalting
• BioProcess medium supported for industrial applications and well-established for desalting and buffer exchange in industrial applications

Storage and Stability

Store at 4 to 30 °C (4 to 8, Used Media 20% Ehtanol or 0.01 M NaOH)
