Let's face it, Immobilized rProtein ATM is not an "inert" substance. Its value is directly related to its IgG binding activity. And immobilized recombinant Protein A from Repligen has more IgG binding activity per ml (> 20 mg human polyclonal IgG per ml) orYCper S (as low as $.30/mg igG binding capacity*) than the other brands. Repligenfs rProtein A is readily available in two forms: immobilized to crosslinked 4 % agarose beads in milliliter and multiliter quantities or as an ultrapure lyophilized protein in laboratory and multigram quantities. For more information, please call (617) 225-6000. Or write REPLIGEN Corp., One Kendall Square, Bldg. 700, Cambridge, Massachusetts, 02139 Attention Customer Service.
