Northern Blotting is a laboratory technique used to detect and measure RNA levels in a cell. There are several alternative names for Northern Blotting, including RNA gel blotting, RNA hybridization, and RNA dot blotting. RNA gel blotting refers to the separation of RNA molecules by electrophoresis on a gel matrix, followed by transfer to a membrane and hybridization with a probe. RNA hybridization refers to the specific binding of a labeled RNA probe to a complementary RNA target sequence, while RNA dot blotting involves the application of RNA samples to a membrane and hybridization with a probe. Overall, these synonyms are useful for understanding the varied approaches to RNA analysis in the lab.
