Northern rna marker
WebNorthern blot protocols begin with RNA isolation, and separation techniques vary depending on RNA size. Large RNAs are separated by electrophoresis on a formaldehyde agarose gel or glyoxal agarose gel, which prevents normal base paring and maintains RNA in a denatured state. Small RNAs are separated on a denaturing (urea) polyacrylamide gel. WebRNA Molecular Weight Marker I, DIG-labeled, is used as a size standard in northern blot analysis when the DIG System for Nucleic Acid Labeling and Detection is used. The …
