应用

在细胞周期平台分析期间，牛胰腺核糖核酸酶B可用于消化RNA。

生化/生理作用

通过枯草杆菌蛋白酶消化天然RNase B（包含RNase B的氨基酸残基21-124）产生的天然RNase BS对PNGase F消化敏感。 牛胰腺RNase B的分子内N-聚糖具有伴侣蛋白的作用。 已有研究发现RNase B比RNase A起效更快，而RNase A在再生过程中易于聚集。Asn-寡糖（对应于RNase B的最主要糖链）的刺激作用表面RNase B的N-聚糖可促进大体积中间体转化为折叠的紧密物种。

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How should Ribonuclease B from bovine pancreas, Product R7884, be reconstituted?

    This product may be reconstituted directly in water at a concentration of 1 mg/mL.

  4. What is the extinction coefficient of Ribonuclease B from bovine pancreas (RNase B), Product R7884?

    The E1% for this enzyme is 8.0 when measured at 280 nm.

This paper describes a chaperone-like function of the intramolecular N-glycans of bovine pancreatic RNase B. We studied air-oxidative regeneration from reductively denatured species of RNase B and its nonglycosylated form, RNase A. RNase B was reactivated much faster than RNase

In glycoanalysis protocols, N-glycans from glycoproteins are most frequently released with peptide- N (4)-( N-acetyl-beta-glucosaminyl)asparagine amidase F (PNGase F). As the enzyme is an amidase, it cleaves the NH-CO linkage between the Asn side chain and the Asn-bound GlcNAc residue.

Protein glycosylation is important in many organisms for proper protein folding, signaling, cell adhesion, protein-protein interactions, and immune responses. Thus, effectively determining the extent of glycosylation in glycoprotein therapeutics is crucial. Up to now, characterizing protein glycosylation has been carried

N-Acetylglucosamine (GlcNAc) is an essential monosaccharide required in almost all organisms. Fluorescent labeling of the peptidoglycan (PG) on N-acetylglucosamine has been poorly explored. Here, we report on the labeling of the PG with a bioorthogonal handle on the GlcNAc. We
