Sephadex G-15 is well established gel filtration medium for desalting and buffer exchange of peptides and small biomolecules >1 500 molecular weight.

Quickly desalts, removes contaminants and transfers to a new buffer in a single step.

Suitable for buffer exchange and cleanup of biological samples, for example peptides, small proteins, and oligosaccharides larger than 1 500 molecular weight

Efficient removal of contaminants such as salts, dyes, and radioactive labels

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-15 is one of five different G-types ranging from G-10 for small molecules to G-75 for larger molecules. Sephadex G-50 is available in 4 different particle sizes (Coarse, Medium, Fine & Superfine) and Superfine has the smallest bead size for higher efficiency with shorter diffusion distances. Coarse and Medium are are preferred for large scale group separations at where high flow rates and low operating pressures are required.

Handbook

Size Exclusion Chromatography: Principles and Methods Summary This handbook describes the use of SEC for the purification and separation of biomolecules, with a focus on practical information for obtaining the best results. The media available, selection criteria and examples with detailed instructions for the most common applications are included, as well as the theoretical principles behind the technique. The first step towards a successful separation is to select the correct medium and this handbook focuses on the most up-to-date SEC media and prepacked columns. Close
