Details

Product Information

Product description: RNase III, E.coli is a homodimeric, divalent metal ion dependent nuclease. RNase III cleaves long double-stranded RNA (dsRNA) into short 12-30 base dsRNAs containing a 5'-PO4, 3'-OH, and a dinucleotide 3' overhang.

Source: Recombinant E.coli

Concentration: 0.5U/μL

Unit Definition: One unit is the amount of enzyme required to digest 1μg of dsRNA to siRNA in 20 minutes at 37℃ in a total reaction volume of 50μL.

Storage Buffer: 500mM NaCl, 20mM Tris-HCl (pH 8.0, 25℃), 0.5mM EDTA, 0.5mM DTT, 50% Glyercol.

Companion Product:
10X RNaseIII Reaction Buffer, Cat#ON-078, 500mM Tris-HCl (pH7.5, 25℃), 500mM NaCl, 10mM DTT
10X MnCl2, Cat#ON-079, 200mM MnCl2
10X EDTA, Cat#ON-080, 500mM EDTA

Key points of operation

Recommended protocol:

  1. In ice, combine the following, in order:

ddH2O
X μL
10X RNase III Reaction Buffer
10μL
dsRNA
X μL (10μg)
RNase III
10-20 units
10X MnCl2
10μL
Total Volume
100μL

  1. Mix and incubate for 20 minutes at 37℃.
  2. Add 10μL 10X EDTA to stop the reaction.

Security Information

Storage Conditions:

Long term (Infrequent use): -70℃

Daily/Weekly use: -20℃*

Do not store in a frost-free freezer.

Always avoid freeze-thaw cycles or exposure to frequent temperature changes. These fluctuations can greatly alter product stability.

* RNase III stores at -20℃ may result in the formation of haze. If this happens, keep the tube at room temperature until tube temperature is up to 4~10℃. Then mix gently to clarify the solution. Haze should disappear. And there is negligible loss of activity.

Quality Assurance: Free of Endonuclease, Exonuclease, and Nickase activities. Pass functional testing

Physical Purity: >90% by SDS-PAGE.
