Grade DE81
A thin (0.20 mm) DEAE cellulose paper – a weakly basic anion exchanger with diethylaminoethyl functional groups. The ion exchange capacity is 1.7 µeq/cm2 and wicking flow rate is 95 mm/30 min. For use with reverse transcriptase assays and DNA polymerase. Also available in multiwell filter plates (Mesh Bottom UNIFILTER). Grade P81
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). Grade SG81
A novel paper (0.27 mm thick) combining cellulose and large pore silica gel. Not charged, but binds polar molecules from less polar solvent. Suitable for separations in which both partition and adsorption are important, including the separation of phospholipids, steroids, phenols and dyes. Flow rate is 110 mm/30 min. Ion Exchange Celluloses are also available as microgranular and fibrous media. |
