What is the difference between GlycINATOR Immobilized and IgGZERO Immobilized?

In both products the enzyme is immobilized on agarose beads for IgG-specific hydrolysis of the Fc glycans to the innermost GlcNAc. IgGZERO Immobilized contains IgGZERO (EndoS) and GlycINATOR Immobilized contains GlycINATOR (EndoS2). The GlycINATOR enzyme has much higher enzymatic activity for high mannose and some bisected and hybrid glycans that can occur on mAbs.
