KANEKA KanCap™ L is a newly developed cellulose-based Protein L resin that exhibits an increased affinity to VL region of antibody κ light chain.

The resin was designed for capture and purification of a wide range of antibody fragment formats such as scFv, Fab and F(ab’)2.

KANEKA KanCap™ L is also an alternative tool to purify full length antibody formats containing a κ light chain which poorly binds to Protein A resins.

Full Length Antibody


> High binding capacity for antibody molecules containing a κ light chain
> Wide binding range for antibody molecules containing a κ light chain

Ligand Design

Selection of the ligand having the widest binding spectra and the highest binding affinity to Fabs was made by screening multiple Protein L mutants.

Ligand Design
Affinity comparison of wild type protein L and KANEKA KanCap™ L’s Protein L to different antibody fragments.


Excellent purification tool for antibody fragments
