PROTEIN Series
The PROTEIN KW series from Shodex™ includes various columns for aqueous size exclusion chromatography (gel filtration chromatography, GFC). The silica-based phases are suitable for analysing water-soluble molecules such as proteins, enzymes or antibodies. Due to the availability of different pore sizes, a large molecular weight range is accessible.
Compared to the columns of the KW-800 series, the columns of the KW-400 series have smaller particle diameters in some cases and are supplied in smaller column dimensions. This enables fast and highly efficient analyses.
The PROTEIN LW series from Shodex™ are also silica-based gel filtration columns (GFC). The series was specially developed for analysing antibody drugs and proteins up to 700,000 Da.
The LW-403 column is a semi-micro column and achieves about half the analysis time compared to the LW-803.
