Sephadex G-100, 100 g
Quickly desalts, removes contaminants and transfers to a new buffer in a single step.
Classic gel filtration medium.
Sephadex is a gel filtration medium prepared by crosslinking dextran with epichlorohydrin. Different types of Sephadex differ in their degree of crosslinking and hence in their degree of swelling and their molecular fractionation range. Sephadex G1NA is one of five different Gtypes ranging from G1NA for small molecules to G75 for larger molecules. Sephadex G5NA 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 where high flow rates and low operating pressures are required.
