Comparison of SEC Separation of Standard Proteins (LW-803, KW-803)
Standard proteins were analyzed with PROTEIN LW-803 which is a column for Aqueous SEC (GFC). PROTEIN LW-803 is suitable for analyzing proteins with a molecular weight of several hundreds of thousands. Furthermore, this column is especially suitable for separating γ-Globulin with the molecular weight of 160,000 and vicinity. The samples are better separated with LW-803 than a conventional column (KW-803) or other manufacturer’s columns. Improvement of separation performance for this molecular weight range is effective for separation of monomer and dimer of IgG which is the mainstream of antibody drugs.
