Cytiva's Whatman™ Grade P81 Ion Exchange Chromatography Paper
Cytiva's Whatman™ Grade P81 ion exchange chromatography paper is a thin cellulose phosphate paper which is also a strong cation exchanger of high capacity. For use with protein kinase assay with peptide substrates. Paper allows for simultaneous development of multiple samples on the same sheet under identical conditions. Sequential development of the same samples with different solvents or different concentrations of the same solvent is possible. Suitable for two dimensional chromatography (change in direction of the solvent front) with possible improved resolution. Used in enzyme assays to separate product from reactant by charge or polarity. Ion exchange capacity is 18.0µeq/cm2 and the flow rate is 125mm/30-Minutes. Thickness: 0.23mm.
