Use SureBeads Protein G Magnetic Beads for fast, easy, and reliable bioseparations: immunoprecipitation (IP), co-immunoprecipitation (co-IP), and protein pull-down assays.

Superparamagnetic beads with surface-activated hydrophilic polymer and chemically conjugated protein A bind the Fc regions of immunoglobulins with high specificity.

• Faster IP using magnetization instead of centrifugation
• Unique bead surface chemistry ensures optimal antibody orientation for increased antigen binding efficiency
• High IgG binding affinity with low nonspecific binding and reduced antibody consumption
• Beads cling magnetically to the side wall of the tube, not the bottom, for easier wash pipetting
