Human control serum was analyzed using aqueous solvent SEC (GFC) high performance semi-micro columns, KW403-4F and KW404-4F. The bigger pore size (1,500 A compared to 800 A) of packed gel in KW404-4F is suitable for the analysis of large molecules that were excluded as void when using a KW403-4F column.
