Application The DIG Northern Starter Kit produces DIG-labeled RNA probes that can be used in conjunction with the supplied chemiluminescent detection reagents for northern blotting techniques. Using linearized DNA as a template, SP6, T3, or T7 RNA Polymerases are used to incorporate DIG-11-UTP into the RNA transcript. After labeling, the DIG-labeled probe is immediately ready for use in hybridization. For convenience, DIG Easy Hyb can be used for hybridization. The DIG Easy Hyb granules are easily reconstituted by adding 64 ml DEPC-treated (RNase-free) water directly to the bottle (once reconstituted, DIG Easy Hyb is stable for 1 month at room temperature). After hybridization, the hybridization solution containing the DIG-labeled RNA probe can be stored at –15 to -25°C for future re-use (up to 1 year). Product Description Sensitivity and specificity: Using 1 µg of linearized template DNA, the labeling reaction typically yields 20 µg of newly synthesized DIG-labeled RNA within 1 h. The DIG-labeled RNA probe can detect 0.1 pg of homologous DNA or RNA in a dot blot. Rare mRNAs can be detected in 0.1 µg of total RNA. |
