Description
The RNase inhibitor (RNase inhibitor) is a specific ribonuclease (RNase) inhibitor that exists in human placenta. The principle of specific inactivation of RNase is: non-covalent bond with RNase to form a complex, resulting in RNase is inactivated.
The product is a purified recombinant murine RNase inhibitor expressed in E.coli in soluble form. It can extensively inhibit various RNases (RNase A, B, C). According to RT-PCR and RT-qPCR, this product can be compatible with HifairTM V Reverse Transcriptase (Cat#11300) and various DNA Polymerases. Compared to human-derived RNase inhibitors, the murine version lacks two oxidation-sensitive cysteines, giving it higher antioxidant stability and making it better suited for DTT-sensitive applications like qPCR.
The product can be applied to 1st strand synthesis of cDNA, polysome isolation, in vitro reverse transcription and in vitro cell-free translation system.
This glycerol-free formulation is specially designed for lyophilization.

Application
This product is ideal for preventing RNA degradation in any workflow where RNase contamination may occur, including:
cDNA synthesis & RT-PCR – Compatible with both PCR and qPCR systems.
In vitro transcription/translation – Protects RNA in systems such as viral replication assays.
RNA isolation & purification – Maintains RNA integrity throughout the process.
RNase protection assays – Ensures accurate and reliable results.

Using Yeasen's RNA lyophilizable reagent (Cat#16645ES), which contains Murine RNase Inhibitor (200 U/µL, Glycerol-free) (Cat#10703), both in situ freeze-drying and freeze-dried microspheres were successfully prepared. The in situ freeze-dried product showed a smooth surface with no collapse or tube gap. The microspheres were uniform, plump, and smooth.
3.No residual exonuclease, nicking enzyme, or RNase.
