核糖核酸酶(RNases)無處不在,可通過多種方被引入實驗中而造成實驗污染,例如,抽取RNA的過程中,因手和 pipette tips引起的 RNases污染。RiboSafe RNase Inhibitor 是一種重組蛋白,可以完全抑制各種真核生物RNase,包括RNase A、B和C。
- 完全抑制RNase A、B和 C
- 顯著提高RT-PCR靈敏度
- 不含DNase、RNase和Nickase
- 不抑制 polymerase/transcriptase 活性
- 在廣泛的pH值、溫度和DTT濃度範圍內穩定
適合應用
- RNA purification
- cDNA synthesis
- RNA sequencing
- in vitro RNA transcription
Fig. 1 RiboSafe RNase Inhibitor提供出色的RNA保護
Inhibition of RNase A by RiboSafe RNase Inhibitor and RNase Inhibitor from another supplier was assessed with the total Yeast RNA assay for the measurement of RNase activity (purple columns) and the pre-incubation-assay (grey columns). RiboSafe RNase Inhibitor blocks RNase A with higher efficiency than other commercially available RNase inhibitors.
Fig. 2 RiboSafe inhibits可有效抑制高濃度RNase A
2 μg of total human HeLa cell RNA was incubated with 20 Units of RiboSafe RNase Inhibitor and 2 ng, 750 pg, 250 pg and 125 pg of RNase A (lanes 1-4) at 37°C for 30 min. Controls were no RiboSafe RNase Inhibitor (lane 5) and total HeLa cell RNA (lane 6) and 2 μg of total human HeLa cell RNA incubated with 125 pg RNase A. HyperLadder 1 kb (M).
Fig. 3 RiboSafe對polymerase沒有抑制性
A two-fold serial dilution of Total HeLa cell RNA (1 μg - 0.075 μg) was reverse transcribed in the presence and in the absence of RiboSafe RNase Inhibitor, followed by the amplification of a 1 kb fragment of the Angiotensin receptor II gene using (lanes 1-10). HyperLadder 1 kb (M).
Fig. 4 RiboSafe RNase抑製劑在高達55°C的溫度下仍具有活性
2 μg aliquots of mouse total RNA were incubated at 37 °C with RiboSafe RNase Inhibitor and no RNase A (lane 1), no RiboSafe RNase Inhibitor and RNase A (lane 2), or with RiboSafe RNase Inhibitor and RNase A at 37 °C, 42 °C, 45 °C, 50 °C, and 55 °C for 30 minutes (lanes 3—7, respectively, HyperLadder 1kb (M)). Regardless of the temperature, there is no visible RNA degradation when incubated with RiboSafe RNase Inhibitor
