Shodex PROTEIN KW and PROTEIN LW SEC Columns

Shodex PROTEIN KW and PROTEIN LW are silica-based SEC columns for the separation by size of proteins and enzymes. The range consists of the PROTEIN KW-800 series, PROTEIN KW-400 series, and the PROTEIN LW series.

PROTEIN KW-800 series is based on silica particles whose surface is coated with a hydrophilic polymer making it suitable for aqueous SEC. It is well suited for the analysis of proteins and peptides.

PROTEIN KW-400 series is the high performance semi-micro version of the KW-800 series. By using a smaller particle size of 3 µm the theoretical plates and sensitivity are improved. The KW405-4F has a larger pore size than any columns in the existing KW-800 series, and can be used to analyse proteins with molecular weight larger 1,000,000 Da.

PROTEIN LW series columns have optimised pore sizes for the analysis of monoclonal antibodies (mAbs) with molecular weights of several hundred thousand.
