Description and Specification


Description Pierce Protein L Magnetic Beads
Formulation Recombinant Protein L monolayer covalently coupled to blocked superparamagnetic beads; supplied at 10mg/mL in PBS containing 0.05% Tween-20 and 0.05% NaN3
Quantity 5mL
Sufficient For Binding at least 1000µg human IgG/mL of bead

Recombinant Protein L, covalently attached to a blocked magnetic bead surface, selectively binds mouse and human antibodies through kappa light chains. The beads are commonly used to purify monoclonal antibodies in cell culture supernantants supplemented with bovine serum as Protein L does not bind bovine IgG. The Pierce Protein L Magnetic Beads can be used manually with a magnetic stand, as well as with automated platforms such as the Thermo Scientific™ KingFisher Instruments for high-throughput workflows.


  • Selective – immobilized Protein L is ideal for selective purification of human and mouse antibodies that have kappa light chains

  • Low non-specific binding – stable, pre-blocked beads provide clean purification of antibody

  • Versatile – beads are compatible with manual and automated workflows (e.g., Thermo Scientific™ KingFisher Instruments)

Recommended for:

  • Purification of monoclonal and polyclonal antibodies that bind poorly to Protein A or Protein G magnetic beads
  • Purification of monoclonal antibodies from culture supernatants supplemented with bovine serum
  • Protein L IP and co-IP assays
  • Purification of ScFv and Fab fragments containing kappa light chains
