Comparison of Separation of BSA Aggregates (LW-803, KW-803)

BSA and its aggregates were separated with PROTEIN LW-803 which is an aqueous SEC (GFC) column, and a conventional column (KW-803). With KW-803, the tetramer can be detected, however, the pentamer can be detected with LW-803. It is confirmed that LW-803 provided a better separation of the monomer and dimer than KW-803.
