BERUS RNase A is a bovine endonuclease, targeting and degrading single-stranded and double-stranded RNA. The enzyme (13.9kDa) will cleave RNA at C and U residues at the phosphodiester bond, increasing the DNA purity of your sample. The enzyme activity of the BERUS RNase A is easily adaptable to single-stranded or double-stranded RNA depending on the solutions conditions, without the concern of reducing the quantity or quality of your DNA sample.

  • DNase free – Unlike other products, the BERUS RNase A does not require heat treatment to remove any DNase.
  • Versatile  This RNase A can be used in a variety of different applications.
  • Easy to use – This enzyme arrives ready to use, premixed in a storage buffer specialised to maximise enzyme activity.

For research use only. These products should not be used for diagnostics

The BERUS RNase A received ready to use for any application you may require. The enzyme is stored in a buffer designed to maximise enzyme activity, without the need to remove DNases or proteases before use. Our recommendation is to use the BERUS RNase A between 5-100µg/mL.

If using the BERUS RNase A to cleave only single-stranded RNA, please be advised to use sodium chloride.

For more information about how to use the BERUS RNase A, please see the package insert.

  • Preparation and isolation of plasmid DNA
  • RNA removal in recombinant protein preparations
  • DNA or RNA single-base mutations

This enzyme cannot be inactivated, however the RNase A is successfully removed from your DNA sample by using a spin column or phenol/chloroform extraction.
