immobilize your ligand for custom magnetic assays Magnetic Protein Immobilization Beads Thermo Scientific Pierce NHS-Activated Magnetic Beads enable covalent, amine-based conjugation of proteins to magnetic beads in a simple mix-and-go format for use in custom affinity purification experiments. The activated magnetic beads contain N-hydroxysuccinimide (NHS) functional groups that react with primary amines, forming stable amide linkages. Once they are covalently attached, the immobilized proteins are highly resistant to leaching from the bead surface. When prepared beads are used in...

immunoprecipitation assay Magnetic Immunoprecipitation Beads The Thermo Scientific Pierce Protein A/G Magnetic Bead is a single particle that is compatible with all commonly used antibodies for immunoprecipitation (IP). These beads are coated with genetically engineered Protein A/G, a recombinant protein that combines the IgG binding domains of both Protein A and Protein G. This combination enables the capture of antibodies from a wider range of species and isotypes than either protein alone. Using our crosslinker chemistry, you can immobilize an antibody onto the magnetic particle and...

Rabbit Polyclonal Thermo Scientic Pierce Protein A/G Dynabeads Protein G Dynabeads Protein A Rabbit Polyclonal Figure 5. The rabbit IgG binding capacity of Thermo Scientific Pierce Protein A/G Magnetic Beads is approximately four times greater than that of the leading brand of Protein A and Protein G beads. Pierce Protein A/G Magnetic Beads or Dynabeads Protein A or Protein G (Life Technologies) were added to a 96 deep-well plate (1mg beads per well). Using the KingFisher 96 Instrument, the beads were incubated for one hour with varying amounts of purified rabbit IgG (20 to 200µg). After...
