Grade:BR.
Molecular weight: 51000.
Caption: RNasin is a specific RNA enzyme inhibitor extracted from human placenta. It is a protein with a molecular weight of 51000 Dalton and an isoelectric point (pH) of 4.7.
It can specifically combine with RNase with an inhibition constant of 300 (ki) to form a complex with a non-covalent bond, resulting in the inactivity of RNase.
Its activity was maintained when the buffer was 0-0.5m NaCl and pH5-8, and the activity was the highest when pH7.8 was used.
After strict quality inspection, the product is electrophoretic pure, free from RNase and Nickase pollution, and the specific activity is 100000 units / mg protein.
Characteristics of RNA enzyme inhibitors:
Inhibition of general eukaryotic RNase including RNaseA, B, C and human placental RNase.
two..
Does not inhibit RNase H, S1 nuclease, SP6, T7 and T3 RNA polymerase, AMV or M-MLV reverse transcription.
Enzyme, Taq DNA polymerase, RNase T1.
Active pH has a wide range, but 1mM DTT is needed to maintain its activity.
Concentration: 40u/ul.
RNA enzyme inhibitor unit definition: the amount of enzyme required to inhibit 50% of 5ng RNase An activity is one unit.
Storage buffer: 20mM HEPES-KOH pH7.6, 50mM KCl, 8mM DTT, 50% glycerol.
Selective inhibition of nuclease by RNA inhibitor: inhibition of RNase A, RNase B, RNase C; no inhibition of RNase T1, S1 nuclease, Rnase from Aspergillus
Activity: inhibition of RNase activity by non-covalent binding with enzyme molecules.
two..
Type of inhibition: competitive inhibition.
Binding constant: Ki=4.4 × 1014.
Ratio with RNaseA: 1:1.
Free sulfhydryl group: 30.
Character: suspension
