ScriptGuard™ RNase Inhibitor will now be sold as RiboGuard™ RNase Inhibitor. There is no change in product specification or price, only
product name and catalog numbers have changed. (SRI6325 is now RG90925, and
SRI6310K is now RG90910K.)
RiboGuard™ RNase Inhibitor is the best defense against common RNases,
including RNase A, RNase B, and RNase C. This recombinant RNase inhibitor protein
provides reliable protection of valuable RNA samples by binding strongly to
RNases in a 1:1 ratio. Advanced purification protocols and extensive quality
control tests ensure RiboGuard RNase Inhibitor is free of unwanted contaminants
that can plague other commercially available preparations of RNase inhibitors.
Unit Definition: One unit of RiboGuard RNase Inhibitor results in 50%
inhibition of 5 ng of RNase A. Activity is measured by the inhibition of hydrolysis
of 2,3´-cyclic monophosphate by RNase A.
Storage Buffer: 50% glycerol solution containing 50 mM Tris-HCl (pH
7.5), 0.1 mM EDTA, 100 mM NaCl, and 10 mM DTT.
Quality Control: RiboGuard RNase Inhibitor is free of detectable DNA
exo- and endonuclease, and RNase activities.
