Comparison of SEC Separation of IgG between LW-403 4D and LW-803

Print

PROTEIN LW-403 4D is an aqueous SEC (GFC) semi-micro column for rapid analysis of antibody proteins. PROTEIN LW-403 4D and PROTEIN LW-803 (a standard column) were compared for the chromatogram of IgG. The analysis time using LW-403 4D can be completed in half the time compared to LW-803.
 

Sample : IgG from human serum 10mg/mL
(LW-403 4D) 0.5μL
(LW-803) 5μL
