RNaseAlert Lab Test Kit

RNaseAlert Lab Test Kit


Ambion RNaseAlert Lab Test kit is a Patent-pending technology detects RNase activity in a convenient and sensitive assay that delivers results in real time. Suitable for testing small sample numbers and can be used to ensure that solutions, tubes, tips, etc. are RNase-free; the kit contains sufficient reagents for 25 reactions.

• Detects as little as 3.5 x 10-7 units (~0.5 pg) of RNase A, with a fluorometer or by eye
• Simple, straightforward 30 min assay
• Monitor RNase activity in column fractions during protein purification
• Use with DNaseAlert™ to quantitatively detect both RNases and DNases in the same sample

The RNaseAlert QC System uses a novel RNA substrate tagged with a fluorescent reporter molecule (fluor) on one end and a quencher on the other. In the absence of RNases, the physical proximity of the quencher dampens fluorescence from the fluor to extremely low levels. When RNases are present, however, the RNA substrate is cleaved, and the fluor and quencher are spatially separated in solution. This causes the fluor to emit a bright green signal when excited by light of the appropriate wavelength. Fluorescence can be readily detected by eye upon illumination on a UV box, or with a filter-based or monochromator-based fluorometer. Since the fluorescence of the RNaseAlert Substrate increases over time when RNase activity is present, results monitored with a fluorometer can be evaluated kinetically. The sequence of the RNaseAlert Substrate has been carefully optimized to detect several RNases, including RNase A, RNase T1, RNase I, micrococcal nuclease, S1 nuclease, mung bean nuclease, and Benzonase.

Rapid and Convenient Protocol
The RNaseAlert procedure requires just minutes to set up. The lyophilized, fluorescent substrate is reconstituted in the supplied tube and incubated with the test solution at 37°C for 30–60 min. The results are then read on a transilluminator or fluorometer. Samples that noticeably fluoresce compared to the negative control are contaminated and should not be used with RNA. Nuclease-free water and RNase A are provided for use as controls.

Accessory Product:
The RNaseAlert QC System is also available for high-throughput assays in a 96-well format (SKU# AM1966). RNaseAlert is also fully compatible with the Ambion DNaseAlert QC System (SKU# AM1970). Since the DNaseAlert Substrate contains a fluorescent tag that is spectrally distinct from RNaseAlert, the two kits can be used simultaneously with a fluorometer for quantitative real-time analyses of both RNases and DNases within a single sample.
