Általános leírás
Pyrimidine-specific endoribonuclease that acts on single-stranded RNA. RNase, DNase-free, is a heterogeneous mixture of ribonucleases that has been prepared free of deoxyribonuclease activity according to the current Quality Control procedures. RNase, DNase-free, is particularly well suited for use in DNA isolation procedures. Before use, most RNase preparations must be boiled to remove DNase activity. This preparation of RNase does not need to be boiled; it can be used directly from the vial.
Alkalmazás
RNase, DNase-free, efficiently removes contaminating RNA from plasmid or genomic DNA preparations.
Egység definíció
One Kunitz unit is the amount of enzyme that causes a decrease in absorbance of A0 to A1 within one minute under the assay conditions. A0 to A1 corresponds to the total conversion, A1 being the final absorbance.
One unit produces a decrease in absorbance at 260 nm, which is equivalent to a total conversion of RNA to oligonucleotides in one minute at +25 °C.

Fizikai forma
Solution, 500 μg/ml, in 10 mM Tris-HCl, 5 mM CaCl2, 50% glycerol (pH 7.0).
Elkészítési megjegyzés
Working concentration: The optimal working concentration for RNase, DNase free, is 2 to 5 μg/ml. The reaction volume will vary for different applications. Some suggested guidelines are given below:
Working solution: Storage and Dilution Buffer: 10 mM Tris-HCl, 5 mM CaCl2, 50% glycerol (v/v), pH 7.0.
- For small-scale isolation of plasmid DNA ("miniprep" from a 1.5 ml bacterial culture), use 0.5 μl of RNase, DNase-free in a reaction volume of 50 μl.
- To isolate plasmid DNA from a 100 ml bacterial culture, use 8 μl of RNase, DNase-free in a reaction volume of 2 ml.
- To isolate genomic DNA from cultured mammalian cells (5 x 107 cells), use 8 μl of RNase, DNase-free in a reaction volume of 2 ml.
Working solution: Storage and Dilution Buffer: 10 mM Tris-HCl, 5 mM CaCl2, 50% glycerol (v/v), pH 7.0.

Local three-stranded DNA/RNA hybrid regions of genomes (R-loops) have been detected either by binding of a monoclonal antibody (DRIP assay) or by enzymatic recognition by RNaseH. Such a structure has been postulated for mouse and human telomeres, clearly suggested by

Understanding gene regulatory networks in mammalian cells requires detailed knowledge of protein-DNA interactions. Commonly used methods for genome-wide mapping of these interactions are based on chromatin immunoprecipitation. However, these methods have some drawbacks, such as the use of crosslinking reagents
