mRNAs only constitute a small fraction of total RNA in cells. Please note that nitrocellulose membranes are chemically incompatible with the NorthernMax Transfer Buffer and should not be used with these kits. Northern blot is a hybridization technique to visualize and quantify RNAs from cells or tissues using a radio-labeled probe. From Invitrogen TRIzol reagent that enables high. RNA is a single-stranded nucleic acid but. RNA molecules are negatively charged, so they move from negative to the positive electrode during gel electrophoresis. The RNA molecules isolated from cells are separated according to size by Gel electrophoresis. Our Invitrogen portfolio comprises one of the industry’s most comprehensive product offerings for northern blot analysis. The first step in northern blotting is RNA gel electrophoresis. The NorthernMax and NorthernMax-Gly Kits have been optimized to work with the BrightStar-Plus positively charged nylon membranes, and we recommend their use to minimize background and maximize signal. Northern blot analysis reveals information about RNA identity, size, and abundance, allowing a deeper understanding of gene expression levels. Instead of overnight transfer, the transfer takes about 2 hours and delivers higher blot sensitivity by efficiently moving RNA (especially larger transcripts) onto the membrane. With dry blotting, there is no need for additional buffer or liquids that can introduce variability into the result.Īlternatively, we offer a rapid alkaline transfer method that is incorporated into the NorthernMax and NorthernMax-Gly procedure. For fast, reproducible transfer, the iBlot Dry Blotting System offers complete transfer of RNA to nylon membrane typically in 7 minutes. Once separated by denaturing agarose gel electrophoresis, the RNA is transferred to a positively charged nylon membrane and immobilized for subsequent hybridization.
