Description
Synonym: GenElute™ RNAse A
General description
Ribonuclease A (RNase A), a protein composed of three α helices and seven β strands arranged in two “lobes” holds significance as the prototypical domain-swapped protein. It is known for its diverse oligomeric states. The RNase A family derives its name from bovine pancreatic RNase A and is specific to vertebrates. In humans, this family encompasses eight functional members, showcasing its biological relevance.

Application
RNase A solution has been used:
- in apoptosis assay of Hep-2 cells
- for the colorimetric quantification of methylated DNA
- for DNA and RNA extraction
- in DNA laddering analysis
- in cell cycle analysis
- as a component in phosphate-buffered saline (PBS) to incubate cells for flow cytometry.
Biochem/physiol Actions
Ribonuclease A or bovine pancreatic ribonuclease A (RNase A) enzyme is an endoribonuclease that displays a specific ability to cleave single-stranded RNA on the 3′ side of pyrimidine residues. This endonuclease with 124 amino acids plays a key role in gene duplication, cellular metabolism, and cancer therapy. Its overexpression is closely associated with several types of cancer. Hence, RNase A has the potential to be a promising new biomarker for the diagnosis of malignant tumors and is also used as a specific target for new drug discovery. RNase A is commonly used for the isolation of plasmid DNA.
