Descrição geral

Proteomics Grade PNGase F has been extensively purified and lyophilized from dilute potassium phosphate buffer to produce a stable product. The product is free from glycerol and other stabilizers, and contains very low levels of buffer salts. This highly purified material is excellent for N-linked deglycosylation of glycoproteins or glycopeptides in gel, in solution, or on blot membranes.


PNGase F from Elizabethkingia meningoseptica has been used:
  • for de-N-glycosylation of Zika20virus E protein
  • to evaluate coxsackievirus and adenovirus receptor glycosylation using CAR-expressing COS cells
  • to verify the N-linked glycosylation of MHC class 1 polypeptide-related sequence A (MICA)

Suitable for both proteomics and glycobiology use; compatible with MALDI-TOF MS analysis
Used to deglycosylate protein.

Ações bioquímicas/fisiológicas

Cleaves an entire glycan from a glycoprotein provided the glycosylated asparagine moiety is substituted on its amino and carboxyl terminus with a polypeptide chain.

Definição da unidade

One unit will catalyze the release of N-linked oligosaccharides from 1 nanomole of denatured ribonuclease B in one minute at 37°C at pH 7.5 monitored by SDS-PAGE. One Sigma unit of PNGase F activity is equal to 1 IUB milliunit.

Post Translational Modification

Post-translational modifications such as glycosylation, phosphorylation, and sulfation, to name a few, serve many functions. As a result, the analysis of proteins and their post-translational modifications is particularly important for the study of diseases where multiple genes are known to be involved, such as heart disease, cancer and diabetes.
