Drug DiscoveryProtein Kinase AssayUNIFILTERThe <strong>Whatman</strong> Protein Kinase Assay filterplate incorporates a P81 filter in each well.P81 is a cation exchanger that bindspeptides but does not bind unincorporatedATP, resulting in low non-specificbackground noise and high sensitivity inkinase assay. The filter plate is produced toANSI/SBS standards in rigid whitepolystyrene or Barex to eliminate opticalcrosstalk problems during Liquid ScintillationCounting. The 150 µL UNIFILTER has shallowwells enabling higher detection sensitivity.Glass MicrofiberUNIFILTER<strong>Whatman</strong> GF/C (1.2µm) and GF/B (1.0µm)Glass Microfiber Filters are widely used forliquid scintillation assay and cell harvest. The<strong>Whatman</strong> Glass Microfiber UNIFILTER has a350 µL well volume and mesh bottomconfiguration.Solvent RetentionUNIFILTER forCombinatorial ChemistryThe Solvent Retention UNIFILTER,constructed from rigid and chemicallyresistant polypropylene, incorporates aunique oleophobic PKP filter which aids theprocess of parallel synthesis. The PKP filterhas been treated to retain a large number oforganic solvents as well as water withoutleakage, so there is no need for bottomclamping procedures.Features and Benefits:ORDERING INFORMATIONCatalog Well Well Plate Filter Drip Quantity/Number Format Volume Material Media Director CasePROTEIN KINASE ASSAY UNIFILTER7700-3312 96 350 µL White Polystyrene <strong>Whatman</strong> P81 Short 507700-4312 96 350 µL White Polystyrene <strong>Whatman</strong> P81 Mesh 507700-0512 96 150 µL White Barex <strong>Whatman</strong> P81 Mesh 50GLASS MICROFIBER UNIFILTER7700-4301 96 350 µL White Polystyrene GF/C Mesh 507700-4303 96 350 µL White Polystyrene GF/B Mesh 50SOLVENT RETENTION UNIFILTER7700-7228 96 2 mL Glass Filled <strong>Whatman</strong> Long 10PolypropyleneOleophobic PKP7701-6200* 96 2 mL Multi-Chem — — 107701-5200* 96 2 mL Polypropylene — — 25* Collection Plates• Solvent retaining filter bottom – noclamping necessary.• Filtration achieved only upon theapplication of vacuum or centrifugation.• Long drip directors ensure nocontamination from well to well.Liquid Retained:Water, Concentrated Ammonium Hydroxide,DMSO, Methanol, Ethanol, 1-Propanol,Iso-Propanol, 1-Butanol, AcN, DMF,n-Hexadecane, Mineral Oil, Toluene, p-Xylene,DCM, Chloroform, 1,1,2,2-TetrachloroethaneLiquid Partially Retained:Acetone, MEK, HeptaneLiquid Not Retained:THF, Ethyl Acetate, Pentane, Hexanes,Iso-Octane<strong>Microplate</strong> <strong>Product</strong> <strong>Guide</strong>7
