These cartridges are convenient, ready-to-use prepacked devices for isolation and purification of immunoglobulin classes IgG, IgM, IgA, IgE and IgD via their kappa light chains.

• Immobilized protein L is ideal for selective purification of human and mouse antibodies that have kappa light chains
• Resin support is crosslinked 6% beaded agarose (CL-6B), the most popular resin for protein affinity purification methods
• Superior manufacturing method immobilizes protein L by charge-free, leach-resistant covalent bonds, resulting in low non specific binding and enabling multiple uses without decline in yield
• Binding capacity of 5 to 10 mg human IgG/ml resin
• Storage temperature 4 to 8 °C

Pierce Chromatography Cartridges are compatible with the major automated liquid-chromatography systems or for manual syringe processing, and attach directly to ÄKTA™ or FPLC Systems without additional connectors. An accessory pack, included with each product, readily adapts columns for use with Luer-Lok Syringe Fittings or ¹/₁₆" tubing. Protein L cartridges provide fast, easy and reproducible chromatographic separations and can be regenerated for multiple uses.
