New England Biolabs, S1425S, Protein A Magnetic Beads

Protein A Magnetic Beads are an affinity matrix for the small-scale isolation and purification of immunoglobulins. Specifically, the beads consist of a truncated form of recombinant Protein A that is covalently coupled to a nonporous superparamagnetic particle.
