Description

Use analytical grade AG 11 A8 Ion Retardation Resin for desalting, removing acid from nonionic molecules, and separating ions from ionic substances. Unlike ion exchange, ion retardation can be used to separate mixtures of highly ionized molecules since the mechanism is reversible adsorption. • Absorbs both anions and cations from solutions • Can be used to desalt amino acid solutions and peptides, and remove charged detergents, including SDS, from protein solutions • Ideal for rapid quantitative removal of acids due to H+ being held so strongly that it is not eluted by water • Can be used repeatedly without special regeneration; after most separations water elution is sufficient • Biotechnology grade resin is certified to contain less than 100 microorganisms per gram • Larger volume and special packaging available on request AG 11 A8 Resin contains paired anion and cation exchange sites which are in close proximity and partially neutralize each other (i.e. self-adsorb). This media is composed of a strong anionic resin with a weak cationic polymer trapped inside, so that beads are both cation and anion exchangers. Ions are weakly adsorbed and then desorbed repeatedly as they move through the column. The rate of retardation of an ion is proportional to the strength of adsorption of that ion. AG 11 A8 Ion Retardation Resin is stable in acid, base, and organic solvents and is autoclavable. Avoid exposure to strong oxidizing agents. Product Options *Biotechnology-grade resin is certified to contain less than 100 microorganisms per gram; molecular-biology-grade resin is certified to be endo- and exonuclease-free and contain no ligase inhibitors ** Irreversibly bound dye that turns from blue to gold when exchange capacity is exhausted Related Products • Poly-Prep ® Chromatography Columns hold up to 2 ml resin, polypropylene • Econo-Pac ® Chromatography Columns hold from 1 to 20 ml resin, polypropylene • Glass Econo-Column ® Columns Related Categories • Chromatography Systems, Components, and Accessories • BioLogic™ Low-Pressure Liquid Chromatography Systems • Chromatography Resins • Chromatography Columns Supporting Documents • AG 501-X8 and Bio-Rex MSZ 501(D) Mixed Bed Resin Instruction Manual • Analytical Grade AG 11 A8 Ion Retardation Resin Instruction Manual Online Resources • Chromatography
