M4 PNGase F
Category: Enzymes & Accessories
M4 PNGase F (EC: 126.96.36.199) is used for deglycosylation of proteins. The highly pure enzyme of MEDNA is excellent for cleavage of N-linked glycan from glycoproteins. M4 PNGase F can be used for any application that requires the removal of N-linked glycans from proteins, for example, studying the N-glycosylation of proteins of interest by mass spectrometry.
Glycosylation is a common post-translational modification with an important role in many cellular processes. It also affects the efficacy of biologics therapies. PNGase F is an effective tool to study the glycosylation status of proteins of interest. PNGase F (peptide-N-glycosidase F), also known as peptide-N4-(N-acetyl-β-glucosaminyl) asparagine amidase, releases intact N-glycans by cleaving between the innermost GlcNAc of the N-glycan and an Asparagine (Asn) residue.
