RNase A, Solution
RNase A specifically cleaves single-stranded RNA at 3' phosphate linkages of pyrimidine residues leaving pyrimidine 3' phosphates and oligonucleotides with terminal pyrimidine 3' phosphates(1).
Molecular Weight: 13.7 kDa
Optimum pH: 7.0-7.5
Inhibitors: Heavy metal ions, RNase Inhibitors, vanadyl-ribonucleoside complexes.
The enzyme is chromatographically purified. Aggregate free, monophoretic on native gel electrophoresis.
0.1M phosphate buffer containing 0.1% v/v phenol as a preservative.
One unit hydrolyzes yeast RNA liberating soluble oligonucleotide causing an increase in absorbance at260 nm of 1.0 at 37°C, pH 5.0.
