PNGase A


  • Product Code: LZ-rPNGaseA-01-S
  • Size 150 units

  • £311

PNGase A cleaves between the innermost GlcNAc and asparagine residues of high mannose, hybrid, and short complex oligosaccharides such as those found in plant and insect cells from N-linked glycoproteins and glycopeptides. PNGase A differs from PNGase F in that it cleaves N-linked glycans with or without α(1,3)-linked core fucose residues.

  • Cleaves N-glycans from plant and insect-derived glycoproteins and glycopeptides
  • Activity is not inhibited by an α1-3 Fucose residue on the chitobiose core
  • Recombinant enzyme with no detectable exoglycosidase or other endoglycosidase contaminating activities
  • Glycerol-free for optimal performance in HPLC and mass spectrometry analysis
  • ≥95% purity, as determined by SDS-PAGE and intact ESI-MS
  • Optimal activity and stability for up to 24 months 

Product specification:


PNGase A is a recombinant amidase, which cleaves between the innermost GlcNAc and asparagine residues of high mannose, hybrid, and short complex oligosaccharides such as those found in plant and insect cells from N-linked glycoproteins and glycopeptides. PNGase A differs from PNGase F in that it cleaves N-linked glycans with or without α(1,3)-linked core fucose residues.


Product Source: Cloned from Oryza sativa (rice) and expressed in Pichia pastoris.

Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme required to remove > 95% of the carbohydrate from 1 µg of denatured recombinant Avidin produced in Maize in 1 hour at 37°C in a total reaction volume of 10 µl.

Reaction Conditions

1X GlycoBuffer 3

Incubate at 37°C


1X GlycoBuffer 3

50 mM sodium acetate

(pH 6 @ 25°C)


Storage Buffer

20 mM Tris-HCl

50 mM NaCl

5 mM EDTA

pH 7.5 @ 25°C


Heat Inactivation

Unit Assay Conditions

1 μg of recombinant Avidin is denatured with 1X Glycoprotein Denaturing Buffer at 100°C for 10 minutes. After the addition of NP-40 and GlycoBuffer 3, two-fold dilutions of PNGase A are added and the reaction mix is incubated for 1 hour at 37°C. Separation of reaction products are visualized by SDS-PAGE.
