deGlycIT™ (Immobilized IgGZERO®)

deGlycIT spin columns contain IgGZERO enzyme covalently coupled to agarose beads for deglycosylation of Fc-glycans without contaminating the final preparation with enzyme.

IgGZERO (EndoS) is an IgG-specific endoglycosidase acting on complex type N-glycans at the Fc-glycosylation site of IgG.

Detailed Information

Immobilized IgGZERO enzyme (deGlycIT) on agarose in convenient spin columns. The spin columns are available in three different sizes for deglycosylation of up to 0.5 (Microspin), 10 (Midispin) or 100 (Maxispin) mg IgG.

The smallest columns are available in three different pack sizes with 2, 5 or 10 columns per pack. The enzyme hydrolyzes the β1,4 linkage between the core GlcNAc residues in the Fc-glycan, leaving the innermost GlcNAc intact on the Fc. IgG is incubated with the agarose beads for 15 min, and deglycosylated IgG is then collected by a 1 minute centrifugation step. Since the enzyme is immobilized on agarose beads, there is no need for extensive purification to remove the enzyme.

deGlycIT deglycosylates IgG under physiological reaction conditions, thus preserving the immunoreactivity. Deglycosylation is performed at room temperature.

The enzyme has limited activity on high-mannose and hybrid-type glycans. If you are interested in endoglycosidases that hydrolyze these types of glycans, we recommend the GlycINATOR product family.

Storage and Stability

Supplied in 20% ethanol, shipped on ice, and should be stored at +4-8°C upon arrival. Do not freeze the product!

Unit Definition

One spin column contains sufficient IgGZERO-coupled agaose beads to deglycosylate 0.5 mg (Microspin), 10 (Midispin) or 100 (Maxispin) mg IgG.

FAQ and Support

Popular FAQ

Yes, IgGZERO/deGlycIT are compatible with most commonly used buffers with pH ranging from 6.0 to 8.0, but the reaction conditions might need to be optimized to ensure optimal deglycosylation.

Yes, many buffers are compatible with IgGZERO/DeGlycIT. Please keep pH close to neutral.

First you could increase incubation time and increase temperature to 37°C. One explanation for incomplete deglycosylation with deGlycIT could be that the antibody has higher amounts of high mannose, hybrid glycans or bisected glycans. For these glycans IgGZERO has low or no activity. High mannose glycans are particularly resistant to digestion recommend you try our other endoglycosidase GlycINATOR (EndoS2). This enzyme has much higher activity on these types of glycans sometimes seen in mAbs.

In both products the enzyme is immobilized on agarose beads for IgG-specific hydrolysis of the Fc glycans to the innermost GlcNAc. The deGlycIT contains immobilized IgGZERO (EndoS) and Immobilized GlycINATOR 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.
