TransGLYCIT Generates Homogenous IgG Glycoforms

TransGLYCIT is a platform that enables specific IgG glycan remodeling and prepares antibodies with defined and homogenous glycoforms using fast and robust enzymatic workflows. With the optional FucosEXO 16 enzyme, afucosylated antibodies can be obtained that enable direct comparison of antibodies with or without core fucose.

TransGLYCIT is available in two product formats:

TransGLYCIT G2S2

Transglycosylation of up to 1 mg of IgG with the G2S2 glycoform.

TransGLYCIT G2S2 Afucosylated

Transglycosylation and defucosylation of up to 1 mg of IgG with the G2S2 glycoform.

The Transglycosylation Workflow

  1. Deglycosylation: The Fc N-glycans are trimmed to the core GlcNAc using the IgG specific Immobilized GlycINATOR® (EndoS2) enzyme that hydrolyses all Fc glycoforms including high-mannose, hybrid, complex and bisecting glycans. With TransGLYCIT Afucosylated, the Immobilized FucosEXO 16 hydrolyzes the α1-6 linked core fucose to obtain afucosylated glycoforms.
  2. Transglycosylation: The engineered glycosynthase TransINATOR catalyzes the transglycosylation reaction between the oxazoline reactive G2S2 glycoform and the exposed core GlcNAc.

TransGLYCIT Product Information

TransGLYCIT is a platform technology for efficient transglycosylation of native IgG in three hours. The robust workflow transglycosylates the antibody Fc N-glycans using enzymatic remodeling, resulting in a homogenous pool of antibodies with a defined glycoform. The technology is available in kit formats to generate antibodies carrying the G2S2 glycan profile, with the option to remove the core fucose using the TransGLYCIT Afucosylated kit. The enzymes in TransGLYCIT are expressed in E. coli and modified with His-tags. TransGLYCIT is provided in kits for processing of up to 1 mg of native IgG.

FAQ

Popular FAQ

Unfortunately no, the enzyme requires trimming of the Fc-glycan using GlycINATOR to enable access to the core fucose substrate.

Yes, the transglycosylation reaction can be performed on all subclasses of human IgG. The reaction is somewhat slower on IgG2 and longer incubation times may be necessary to obtain over 95% transglycosylation.

No, TransGLYCIT is based on IgG specific enzymes and will only transglycosylate IgG.

GlycINATOR is an IgG specific endoglycosidase that hydrolyzes complex, hybrid and high mannonse type glycans on the conserved Fc site on IgG.

The TransGLYCIT platform is developed for transglycosylation of human IgG.
