TSKgel Protein A-5PW, 20 µm, 1.000 Å, PEEK, 4.6x35mm

The TSKgel Protein A-5PW column has been designed for the rapid separation and robust quantification of a variety of antibodies. Monoclonal antibodies from harvested cell culture media can be captured and accurately quantitated in less than 2 minutes per injection. The column can be used for more than 2,000 injections without regeneration or cleaning.

Packed with hydroxylated methacrylic polymer beads, the TSKgel Protein A-5PW column is designed with a high degree of crosslinking, which allows high flow rate for chromatography while still maintaining chromatographic efficiency, peak width and resolution. The recombinant protein A ligand is a code-modified hexamer of the C domain. An enhanced rProtein A ligand is bound to the TSKgel 5PW base bead via multipoint attachment resulting in excellent base stability in 0.1 mol/L NaOH.

The wide range loading capacity of the TSKgel Protein A-5PW column can accurately determine the titer of mAb at various stages of cell culture media processing. The low level of protein A leaching makes this column a good candidate for small scale purification of mAbs for initial characterization.
