| Description RiboINTM RNase Inhibitor is a protein which specifically inhibits ribonucleases. It is used in applications such as in vitro translation, cDNA synthesis, RNA in vitro synthesis, RNA purifications, etc. RNase inhibitor is easier to use and eliminate than the vanadyl ribonucleosides. It has a high binding affinity for pancreatic-type ribonucleases such as RNase A. RiboINTM RNase Inhibitor inhibits a broad range of RNases, including RNase A, RNase B, RNase C, but it is not effective against RNase 1, RNase T1, S1 Nuclease, RNase H. |
|
| Source RiboINTM RNase Inhibitor is purified by affinity chromatography which expressing a cloned porcine liver gene from a recombinant strain of E. coli strain containing an overproducing clone of human placenta ribonuclease inhibitor |
|
| Storage Buffer 20 mM Tris-HCl (pH 8.0), 50 mM KCl, 0.5 mM EDTA, 8 mM DTT, and 50% (v/v) glycerol. |
|
| Storage Temperature Store at -20°C |
|
| Storage Recommendations Avoid multiple freeze-thaw cycles and exposure to frequent temperature changes. RiboINTM RNase Inhibitor requires 1 mM DTT to maintain the activity. |
|
| Quality Control One Unit Definition One unit is the amount of protein required to inhibit the activity of 5 ng of RNase A by 50%. |
|
| Purity RiboINTM RNase Inhibitor has been experimented in 12.5% SDS-PAGE electrophoresis. It’s greater than 90% in purity. The specific activity is >80,000 units/mg. |
|
| Recommended Use cDNA Synthesis: 40 units/20 μl of reaction mixture, RiboINTM RNase Inhibitor protects mRNA and improves total cDNA yields including percent total full length of cDNA. RT-PCR: 40 units/20 μl of reaction mixture. In Vitro Transcription: 20-40 units/10 μl of reaction mixture, RiboINTM RNase Inhibitor has been shown to be useful for the isolation of intact RNA transcripts using T3, T7 and SP6 RNA Polymerases. |
