Applications: Lower crosslinkage resins are used for separation or concentration of peptides, nucleotides, and amino acids. Higher crosslinkage resins are useful for separations of smaller peptides and amino acids, removal of cation, and separation of metal ions.


AG MP-50 Resin
Resin Crosslinkage Approx.
MW Exclusion
Operating Stability/pH Range Min. Wet Capacity (meq/ml) Nominal Density (g/ml) Ionic Forms
Type: Strong cation Macroporous >1,000,000 0-14/0-14 1.5 0.8 Hydrogen
Functional group: R-SO3-
Matrix: Styrene divinylbenzene
Applications: Macroporous equivalent of AG 50W resin. Its effective surface area is approximately 35 m2 per dry gram, which is equivalent to 30-35% porosity. It can be used for adsorption of Ca2+, Mg2+, Na2+, and antibiotics.
Analytical Grade Resin Selection Guide
Analytical Grade Resin Selection Guide


The AG 50W resin, AG MP-50 macroporous resin, and the biotechnology grade AG 50W resin all offer strong acid cation exchange capabilities. The AG 50W resin has been exhaustively sized, purified, and converted to provide accurate, reproducible analytical results. Biotechnology grade AG 50W resin is analytical grade resin that is certified to contain less than 100 microorganisms per gram of resin.

AG 50W and AG MP-50 strong acid cation exchange resins are useful for single-step purification methods, for concentrating cationic solutes, and for analytical determinations of various mixed cationic solutes. They are composed of sulfonic acid functional groups attached to a styrene divinylbenzene copolymer lattice. The amount of resin crosslinking determines the bead pore size: a resin with a lower crosslinkage has a more open structure that is more permeable to high molecular weight substances than a highly crosslinked resin.

AG MP-50 resin is the macroporous equivalent of AG 50W resin. Its effective surface area approximates 35 square meters per dry gram, or 30–35% porosity.

Larger volumes and special packaging for industrial applications are available on request.
