P81 Cellulose

A thin (0.23 mm) cellulose phosphate paper. Strong cation exchanger of high capacity. Ion exchange capacity is 18.0 µeq/cm² and the flow rate is 125 mm/30 min. For use with protein kinase assay with peptide substrates. Also available in multiwell filter plates (Protein Kinase and Mesh Bottom UNIFILTER).

• 2.5CM 100/PK
• P81 ion exchange circles
• Used in enzyme assays to separate product from reactant by charge or polarity
• Suitable for two-dimensional chromatography (change in direction of the solvent front) with possible improved resolution
• Sequential development of the same samples with different solvents and/or different concentrations of the same solvent
• Simultaneous development of multiple samples on the same sheet under identical conditions
