Description_x000D_ Application_x000D_ Highly purified material can be used for preparative deglycosylation or for analytical applications in gel, in solution, or on blot membranes. The enzyme can be removed from preparative operations by utilizing its C-teminal 6x histidine fusion tag._x000D_ Used to deglycosylate protein._x000D_ Biochem/physiol Actions_x000D_ Cleaves an entire glycan from a glycoprotein provided the glycosylated asparagine moiety is substituted on its amino and carboxyl terminus with a polypeptide chain._x000D_ Packaging_x000D_ PNGase F was used for deglycosylation of P-glycoprotein in a study to investigate the dual impact of statins on p-glycoprotein and its effect on doxorubicin cytotoxicity in human neuroblastoma cells. It was used to treat a purified protein, mouse cone ultraviolet (MUV) pigment, before use in quantitative immunoblot analysis in a study It is used to deglycosylate N-linked glycoproteins. Highly purified material can be used for preparative deglycosylation or for analytical applications in gel, in solution, or on blot membranes. The enzyme can be removed from preparative operations by utilizing its C-teminal 6x histidine fusion tag._x000D_ Unit Definition_x000D_ 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.
