Elimination of light chain tailing in reducing capillary

Capillary electrophoresis with sodium dodecyl sulfate (CE-SDS) is a common analytical technique for investigating the purity and molecular size heterogeneity of monoclonal antibody (mAb) drugs. In reducing CE-SDS analysis of mAb-A, the light chain (LC) peak exhibited severe tailing, seriously affecting the purity analysis.

Sodium Dodecyl Sulfate

Sodium Dodecyl Sulfate. SDS is an anionic detergent whose hydrocarbon chain can become linked to hydrophobic regions in the interior of globular proteins, leaving the ionized sulphonate (−SO3−) group jutting out into the surrounding medium, converting a protein's native globular or fibrous tertiary structure into a linear one.
