Application

RNase B is a preferred substrate with PNGase F for demonstration of N-linked deglycosylation using SDS-PAGE or MALDI-MS. The activity of PNGase F is routinely assayed using RNase B by monitoring the pronounced mobility shift in 12% gels after deglycosylation. Proteomics Grade RNase B has been used as a source of N-glycans following enzymatic digestions and subsequent purification. It has also been used as a glycoprotein standard.

Autres remarques

Bovine pancreatic RNase B is a glycoprotein that contains only N-linked glycans. It is a globular protein composed of a single domain that occurs naturally as a lesser component in mixture along with ribonuclease A (RNase A), which is the non-glycosylated core form. RNase B contains a single glycosylation site at Asn34 at which from five to nine mannose residues are attached to the chitobiose core, i.e. Man5-9GlcNAc2. Due to the heterogeneity in the glycosylation at Asn34, RNase B exists as five glycosylated varients, with a molecular weight of approx. 15 kDa.

Qualité

RNAse B Glycoprotein Standard has been highly purified to remove contaminating RNase A.

To clear pathogens from host tissues or biomaterial surfaces, phagocytes have to break the adhesive bacteria-substrate interactions. Here we analysed the mechanobiological process that enables macrophages to lift-off and phagocytose surface-bound Escherichia coli (E. coli). In this opsonin-independent process, macrophage

N-glycosylation is a complex post-translational modification with potential effects on the efficacy and safety of therapeutic proteins and known influence on the effector function of biopharmaceutical monoclonal antibodies (mAbs). Comprehensive characterization of N-glycosylation is therefore important in biopharmaceutical development. In

TREX1 is an endoplasmic reticulum (ER)-associated negative regulator of innate immunity. TREX1 mutations are associated with autoimmune and autoinflammatory diseases. Biallelic mutations abrogating DNase activity cause autoimmunity by allowing immunogenic self-DNA to accumulate, but it is unknown how dominant frameshift
