LabPak products are multi-milliliter containers of TOYOPEARL and TSKgel bulk media products. Typically they contain 3 or 4 different ligand types offered for a particular chromatography mode. They are useful for developmental engineers who wish to familiarize themselves with resin physical properties in different buffer systems. The larger resin amounts in LabPak products allow the packing of wider ID and longer columns than available in the ToyoScreen products. This helps the developmental chemist or engineer to better measure under actual packing conditions such properties as dynamic binding capacity, selectivity and column efficiency.
Application
TOYOPEARL® Size Exclusion LABPAK Samplers allow the use of several TOYOPEARL® resins to determine which works best for a particular application. TOYOPEARL® resins are used in separation media and resins.
A novel cation-exchange resin, Eshmuno™ S, was compared to Fractogel® SO3(-) (M) and Toyopearl GigaCap S-650M. The stationary phases have different base matrices, and carry specific types of polymeric surface modifications. Three monoclonal antibodies (mAbs) were used as model proteins
