Quality and applications

Why Protein L

it binds the kappa light chain without blocking the antigen-binding site, so it captures more Ig classes and antibody fragments (Fab, scFv, domain antibodies) — and any that leaches into product must be measured.

Typical applications
  • Monitoring affinity purification
  • Optimising purification protocols
  • And residual nuclease
  • Carrier-protein testing in biologics
  • Vaccines
