Amicon^® Pro Affinity Concentration Kit Protein A with 3kDa Amicon^® Ultra-0.5 Device

Two attributes of the Amicon® Pro device make it a convenient device for preparing pure, labeled antibody. First, the device enables highly efficient buffer exchange via diafiltration with simultaneous sample concentration in a single 15 minute spin. Second, the entire workflow can be performed within a single device, reducing the potential for sample loss. In this report, we describe the successful use of the Amicon® Pro device for small–scale biotinylation of a target antibody. The biotinylated antibody was used for detection of protein immunoprecipitated from cell lysate.

When you start with consistent yields of active, native-folded protein, you’re giving your experiment the best chance to succeed. If your current protein preps involve juggling columns, dialyzers and multiple transfer steps, you could be introducing variability into your data. For your next protein preparation, choose the simple, gentle method that tackles even the most labile and poorly expressed proteins—the Amicon® Pro purification system. When your proteins behave, your research will flourish.
