Antibody purification involves isolation of antibody from serum (polyclonal antibody), ascites fluid, or from the culture supernatant of a hybridoma cell line (monoclonal antibody). Protein L is a recombinant protein expressed in Escherichia coli (35.8 kDa; 4 IgG binding sites) and is recommended for human or mouse monoclonal antibodies known to have appropriate kappa light chains.

We offer two base supports and a variety of formats to purify antibodies using the Protein L ligand. Our portfolio is designed to meet small-scale (screening) to pilot-scale needs.

  • Multiple formats—magnetic beads, loose resin, spin columns and kits, and FPLC cartridges enable antibody purification from microgram to kilogram scales
  • High performance—resins are designed to maximize protein yield and reduce background
  • Economical—pricing is similar to or better than our leading competitors
