RESIN, G-SEP-50 SUPERFNE, 500G

G-Sep™ is a gel filtration resin comprised of ultrapure cross-linked dextran for desalting and buffer exchange in industrial applications. It exhibits high selectivity, superb resolution, low non-specific adsorption and robust chemical stability. Quickly desalts, removes contaminants and transfers to a new buffer in a single step. Excellent recovery and minimum sample dilution Available in prepacked SpinOUT™ Desalting columns for fast and convenient desalting Molecules purified with G-Sep™ are separated according to size. Smaller molecules pass significantly slower through the column than larger molecules. Two different G-Sep™ resins are available, G-Sep™ 25 and G-Sep™ 50. They differ in their degree of cross-linking and hence in their degree of swelling and their molecular fractionation range. G-Sep™ 25 is better suited for smaller molecules and G-Sep™ 50 is better suited for larger molecules. G-Sep™ 25 and G-Sep™ 50 are both available in 3 different particle sizes (Superfine, Fine, and Medium). The molecular weight cut-off (MWCO) for G-Sep™ 25 is 5 kD for proteins and 10 bases for nucleic acids. The molecular weight cut-off (MWCO) for G-Sep™ 50 is 25 kD for proteins and 20 bases for nucleic acids. Buffer and pH effects on resolution are minimal and purified biomolecules are not significantly diluted (1.5-fold) when processed using G-Sep™. G-Sep™ is autoclavable at 121°C, pH 7 for 30 minutes and is stable in all commonly used buffers, including: 0.2M NaOH; 0.2M HCl; 1M acetic acid; 8M urea; 6M guanidine HCI; 1% SOS, 24% Ethanol; 30% Propanol; and 30% Acetonitrile.
