I did not get complete deglycosylation using deGlycIT, how can I improve digestion?

First you could increase incubation time and increase temperature to 37°C.

Another explanation for not complete deglycosylation could be if the antibody has higher amounts of high-mannose, some hybrid glycans or bisected glycans. For these glycans IgGZERO has low or no activity. Especially, high-mannose glycans are particular resistant to digestion.

If longer incubation time and increased temperature does not increase deglycsylation we would recommend you to try our other endoglycosidase GlycINATOR (EndoS2). This enzyme has much higher activity on these types of glycans sometimes seen in m.Abs.
