Northern blot is a commonly used molecular biology approach for the evaluation of gene expression at transcriptional levels (1). Northern blot is also known as RNA blot, as it reflects gene expressions via detection of the mRNA levels of target genes. A routine Northern blotting procedure starts with total RNA extraction, which is followed by separation of RNAs by electrophoresis. The blotting step refers to the transferring of separated RNAs to a nylon membrane, which is then exposed to specific probes for RNA detection. The probes can be either DNA or RNA with complementary sequences to target RNAs, and are often tagged with radioactive isotopes or chemiluminescent group (Figure 1).
