General description
Crude mixture of RNases.Dry powder (prepared from crystallized ribonuclease).
Human chromosome 14q11.2 shows the presence of all human RNases. Only eight (RNase 1-8) of them were true called as canonical RNases. And the rest nine to thirteen are called as noncanonical RNases. Human RNase 1 is called as HP-RNase or human pancreatic RNase. Human RNase 2 is also called as EDN (eosinophils derived neurotoxin) that is isolated from eosinophils.
Specificity
Heat inactivation: 1 mM EDTA
Application
RNase has been used in DNA ladder assay.
RNase has been used in analysis of DNA fragmentation using agarose gel electrophoresis. It has been used during flow cytometry analysis.
Unit Definition
One unit is the enzyme activity that causes a decrease in absorbance of A0 to A1 within 1 minute under the assay conditions; A0 to A1 corresponds to the total conversion, A1 being the final absorbance.
Preparation Note
Activator: PK requires Mg2+ (or Mn2+, Co2+) and K+ (or NH4+, Rb+) for full activity.
Working solution: It is recommended to dissolve the RNase (1 mg/ml) in water or TE buffer, pH 7.5.
Working solution: It is recommended to dissolve the RNase (1 mg/ml) in water or TE buffer, pH 7.5.
Other Notes
For life science research only. Not for use in diagnostic procedures.

Apoptosis of cardiac myocytes is one of the causes of heart failure. Here we examine the mechanism by which the activation of beta-adrenergic receptor induces cardiomyocyte apoptosis. Terminal deoxynucleotide transferase-mediated dUTP nick end labeling and DNA ladder analyses revealed that

Bacteriophages (phages) are present in almost, if not all ecosystems. Some of these bacterial viruses are present as latent "prophages," either integrated within the chromosome of their host, or as episomal DNAs. Since prophages are ubiquitous throughout the bacterial world

Beta-catenin is a multifunctional protein involved in cell-cell adhesion and Wnt signal transduction. Beta-catenin signaling has been proposed to act as inducer of cell proliferation in different tumors. However, in some developmental contexts and cell systems beta-catenin also acts as
