characteristic
RNase Activity Assay Kit (Fluorometric) enables researchers to measure RNase activity in buffers, reagents, and other components as well as quantitatively evaluate RNAse activity of recombinant enzymes in real time. The assay uses a highly sensitive, specific probe that releases a fluorescent product in the presence of active RNAse. The limit of detection is 0.4 pg RNase/well and limit of quantification is 1.2 pg RNase/well.
Product Information
Evaluation of RNase contamination is necessary for reagents to be used in experiments with RNA. The RNase Contamination Assay Kit detects general RNase activities including non-enzyme based RNA degradation due to heavy metal contamination in samples and high pH. The assay probe is a fluorescein labeled RNA transcript (300-mer). After incubation with a reagent sample the integrity of the RNA probe is analyzed on denaturing PAGE followed by SYBR Gold staining or preferably by scanning with a FAM/Fluorescein capable imaging system like the Typhoon scanner. Most samples (e.g. enzymes, column fractions from enzyme purifications, unlabeled RNA/DNA samples, buffers, or diluents) can be tested directly. The assay is semi-quantitative and is more sensitive if detergent is present.
