RNase Inhibitor (Ribonuclease Inhibitor) has a broad spectrum of RNase inhibitory properties for RNase A/B/C and human placental RNase. The 50 kDa recombinant protein exerts its inhibitory effect by noncovalent binding to RNases in a 1:1 ratio. The product was purified from human placenta by the usage of a combination of ion exchange and affinity chromatography. Concentration of RNase Inhibitor is 20 U/µl. Does not inhibit RNase T1, S1 nuclease, RNase from Aspergillus, RNase H or RNase ONE™ Ribonuclease.
Suitable for all applications with RNA, especially for reverse transcription of RNA into cDNA when eukaryotic RNase contamination occurs.
