GlycINATOR LE (Low Endotoxin) enzyme is supplied as a lyophilized powder with no preservatives added, and is available in 2000 unit vials for deglycosylation of up to 2 mg IgG. This product formulation has low levels of endotoxins per vial (< 0.2 EU).

GlycINATOR (EndoS2) is an IgG-specific endoglycosidase that hydrolyzes all glycoforms present at the Fc-glycosylation site. The enzyme acts on the chitobiose core and leaves the core GlcNAc intact.

Detailed Information 

GlycINATOR LE hydrolyzes the β1,4 linkage between the core GlcNAc residues in the Fc-glycan, leaving the innermost GlcNAc intact on the Fc. It is derived from Streptococcus pyogenes and expressed in E. coli. The enzyme contains a His-tag and the molecular weight is 92 kDa. GlycINATOR deglycosylates all human IgG subclasses and IgG from many different species, including mouse, rat, monkey, sheep, goat, cow, and horse.

Storage and Stability

The GlycINATOR LE enzyme is supplied lyophilized and reconstituted by addition of water. After reconstitution, GlycINATOR LE is stable for 1 month at +4-8°C. The product is shipped at ambient temperature but should be stored at -20°C upon arrival.

Unit Definition

One unit deglycosylates ≥ 95% of 1μg human IgG when incubated in 10mM sodium phosphate, 150mM NaCl, pH 7.4 at 37°C for 30min.

We can only guarantee optimal deglycosylation for one-time use. We do not have a cleaning or regeneration protocol to provide. However, depending on the antibody and the following application the column can be reused. We do not recommend using with different antibodies due to the risk for contamination of carry-over from previous sample. If column reuse is desired store the column in 10-20% ethanol at +4-8°C.

Yes, the GlycINATOR enzyme binds specifically to the Fc region and therefore will not deglycosylate N-linked glycans in the Fab region.

Typically, GlycINATOR is the first choice since it displays enzymatic activity on all glycoforms present on IgG, including complex type, high mannose, bisected and hybrid type glycans. IgGZERO does not hydrolyze high mannose glycans. IgGZERO deglycosylates some species faster as compared to GlycINATOR, for example goat IgG.

IgGZERO (EndoS) and GlycINATOR (EndoS2) are both IgG-specific endoglycosidases that hydrolyses Fc glycans to the innermost GlcNAc. The GlycINATOR enzyme has a broader substrate selectivity and therefore much higher enzymatic activity on high mannose and some bisected and hybrid glycans that can occur on mAbs. IgGZERO deglycosylates some species faster as compared to GlycINATOR, for example goat IgG.

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.
