General description

Ab SpinTrap are prepacked, single-use spin columns for rapid purification of monoclonal and polyclonal antibodies from serum and cell culture supernatants. Designed for small-scale purification of multiple samples in parallel.


Ab SpinTrap is designed for efficient, small-scale purification of monoclonal and polyclonal antibodies from serum and cell culture supernatants. In addition, a protocol for immunoprecipitation is included.

The spin columns are also suitable for use in antibody screening experiments.

Ab SpinTrap columns are used together with a standard microcentrifuge and one purification run is performed in less than 20 min.

Ab SpinTrap contains Protein G Sepharose® High Performance, which has high Protein binding capacity and is compatible with all commonly buffers used in antibody purification with immobilized Protein G media.

For optimal performance in antibody purification, use Ab SpinTrap together with buffers prepared using Ab Buffer Kit.

Features and Benefits

• Rapid and convenient small-scale purification of IgG.
• Protein G Sepharose® High Performance in prepacked spin columns.
• No filtration or centrifugation of different crude samples necessary for antibody purification.
• Classic and crosslink protocols for Protein enrichment (immunoprecipitation).
• Elution conditions formatted for both LC-MS and electrophoresis analysis.
• Elution conditions formatted for both LC-MS and electrophoresis analysis.
