How to design probes for northern blot
WebJan 15, 2010 · Currently, northern blot is the most widely used method for validating small RNAs that are identified by methods such as high-throughput sequencing. We describe a new northern blot-based protocol (LED) for small RNA (∼15–40 bases) detection using digoxigenin (DIG)-labeled oligonucleotide probes containing locked nucleic acids (LNA) … WebThe underlying principle of Northern blotting is that RNA are separated by size and detected on a membrane using a hybridization probe with a base sequence complemen- tary to all, or a part, of the sequence of the target mRNA. Fig. 1 provides a schematic representation of Northern blotting; the separate steps in the process are summarized in
