Capturem Protein A columns and plates provide rapid, high-quality, small-scale purification and screening of monoclonal and polyclonal antibodies. This purification method combines the specific antibody-binding properties of Protein A with novel Capturem technology to provide high-capacity, membrane-based affinity purification. Where resin columns fall short, Capturem Protein A yields highly pure monoclonal and polyclonal antibodies in just 5–15 minutes, from loading the sample through elution. Short residence times greatly reduce the possibility of antibody aggregation or loss of activity, giving downstream applications a higher probability of success.

Protein A is a cell wall protein from the bacterium Staphylococcus aureus with a high affinity for the Fc region of monoclonal and polyclonal IgG-type antibodies from several different species, including mouse, rat, and human. Capturem kits use a novel high-capacity membrane-based affinity technology that has previously been used to purify highly concentrated his-tagged proteins in just minutes at room temperature, via miniprep columns, maxiprep columns, 24-well plates, and 96-well plates.
