Application • RNase protection assays • Remove unspecifically bound RNA • Analysis of RNA sequences • Hydrolyze RNA contained in protein samples • Purification of DNA Pancreatic RNase A specifically cleaves at the 3′-side of pyrimidine (uracil or cytosine) phosphate bonds. Ribonucleases do not hydrolyze DNA, because the DNA lacks 2′-OH groups essential for the formation of cyclic intermediates. RNase can also hydrolyze RNA from protein samples. Preparation Note Salt fractionated and chromatographically purified. 性质 type Type I-A assay ≥60% RNase A basis (SDS-PAGE) form powder mol wt mol wt ~13,700 total impurities salt, essentially free foreign activity protease, essentially free storage temp. −20°C 安全性 Personal Protective Equipment Eyeshields, Gloves, type N95 (US), type P1 (EN143) respirator filter Safety Statements 22-24/25 WGK Germany 3 RTECS RF0760000
