Technical Data
Ribonuclease A (RNase A, Pancreatic Ribonuclease, Rib 1, Ribonuclease A Family 1, Ribonuclease Pancreatic, Ribonuclease RNase A Family 1, Ribonuclease RNase A Family 1 Pancreatic, RNAseA, RNase 1, RNASE1, RNS1)
Ribonuclease A is used to isolate DNA for RNA-free DNA. Ribonuclease A hydrolyzes RNA at C and U residues, cleaving between the 3-Phosphate group of a pyrimidine nucleotide and the 5-hydroxyl group of the adjacent nucleotide, i.e., those cleaving cyclic 2',3'-pyrimidine nucleotide residues either singly or at the termination of purine nucleotide chains (Volkin and Cohn 1953). The composition and structure of ribonuclease A has been extensively investigated. The tertiary structure was reported by Kartha, et al. (1967) and Lin, (1970). Wang, et al. (1975) indicate that flexibility in a three-dimensional structure is essential for optimal catalytic activity. Ribonuclease is inhibited by heavy metal ions and is competitively inhibited by DNA. The effect of denatured DNA is much greater than that of the native nucleic acid (Sekine et al. 1969).

Suitable for use in Immunoblot (Western or Dot blot), ELISA, and Immunoprecipitation. Other applications not tested.

Recommended Dilution:
ELISA: 1:5000-1:22,000 (1ug of Ribonuclease A)
Optimal dilution determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
