TSKgel Protein C4-300 columns are are the newest Reversed Phase columns from Tosoh Bioscience. They are designed for the optimal recovery and resolution of proteins such as recombinant proteins, antibody fragments or PEGylated proteins.

The 300 Å pore size of the TSKgel Protein C4-300 columns are ideal for the separation of proteins. A particle size of 3 μm and optimized ligand density and alkyl length result in better protein and peptide resolution compared to other leading RP-C4 HPLC phases. Latest surface modification techniques and endcapping of residual silanol groups reduce undesirable secondary interactions and peak tailing.
