GlycINATOR (EndoS2) is an endoglycosidase from Streptococcus pyogenes that specifically hydrolyzes glycans at the Fc glycosylation site of IgG. The enzyme has been demonstrated to remove all glycoforms on IgG, including high-mannose, hybrid, complex, and bisecting type glycans (Sjögren et al. 2015). GlycINATOR deglycosylates all human IgG subclasses and IgG from many different species, including mouse, rat, monkey, sheep, goat, cow, and horse. It has been reported to have limited activity on glycans from alpha-1-acid glycoprotein (Sjögren et al. 2013). The enzyme is expressed in E. coli, contains a His-tag, and the molecular weight is 92 kDa.
The enzyme is used to reduce the complexity of antibody-based therapeutics or to study core afucosylation and N-glycan site occupancy. The rapid and mild reaction conditions of GlycINATOR ensure a minimized risk for sample prep-induced modifications (Sjögren et al. 2015).
Available in three different product formats:
GlycINATOR Enzyme – lyophilized enzyme
GlycINATOR LE – lyophilized enzyme with low levels of endotoxin
Immobilized GlycINATOR – immobilized on agarose beads
