Product information
PROTEIN KW-800 series
The packing material of the Shodex PROTEIN KW-800 series is based on silica particles whose surface is coated with a hydrophilic polymer. This column is for aqueous SEC (Gel filtration chromatography (GFC)). It enjoys a positive reputation thanks to its high recovery ratio of proteins and peptide. The PROTEIN KW-800 series comprises three kinds of columns, differing in pore and particle size.
-
Silica-based packed columns for aqueous SEC (GFC) analysis
-
Suitable for the analysis of proteins and enzymes
-
Fulfills USP-NF L20, L33, and L59 requirements
PROTEIN KW400 series
The Shodex KW400-4F series is the high-performance semi-micro column version of the KW-800 series. The theoretical plate number and the sensitivity are improved by reducing the diameter of the packed particle to 3 micrometers. KW405-4F, the newest addition to the KW400 line-up, has a larger pore size than any columns in the existing KW-800 series, and can analyze proteins whose molecular weight is larger than 1,000,000. It enables the scientist to carry out the analysis of protein complexes.
-
Reduced packing material particle size enhances column performance
-
Three to four-fold higher sensitivity than KW-800 series
-
KW405-4F is applicable analyzing samples with molecular weight above 1,000,000
-
Fulfills USP-NF L20, L33, and L59 requirements
PROTEIN LW-803 and LW-403 4D
More and more monoclonal antibodies (mAb) are used for therapeutic drugs. The pore size of the Shodex PROTEIN LW-803 and LW-403 4D is suitable for this analysis.
-
Pore size specifically controlled for analyzing proteins with a molecular weight of several hundred of thousand
-
High performance analysis of antibody drugs and various proteins
-
High lot-to-lot reproducibility
-
Fulfills USP-NF L20, L33, and L59 requirements
