![]() ![]() Please note that nitrocellulose membranes are chemically incompatible with the NorthernMax Transfer Buffer and should not be used with these kits. A northern blot is a laboratory method used to detect specific RNA molecules among a mixture of RNA. 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. 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. In a western blot procedure, proteins are first separated on an SDS-PAGE gel and then transferred to a membrane. The first step in northern blotting is RNA gel electrophoresis. It involves the following steps: Firstly, large weighted DNA is cut into small fragments by using Restriction endonucleases. This method is used for analysis of DNA sequences. 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. Southern blotting is named after Edward M. 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.
