Please note that nitrocellulose membranes are chemically incompatible with the NorthernMax Transfer Buffer and should not be used with these kits. 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. Analogous RNA blotting methods were developed and are now commonly referred to as northern blotting 4, 5. DNA blot hybridization is called Southern blotting, an homage to its inventor, Edwin Mellor Southern 2, 3. Recently, circular RNAs (circRNAs) were described as a new class of. Distinct methods are used for the analysis of DNA and RNA by blot hybridization. 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. Northern blotting enables the specific detection and characterization of RNA molecules. Northern blot analysis can be used to investigate whether a gene is overexpressed or underexpressed in cancer cells as compared to normal cells. 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.

View our RNA Isolation Kit Selection Guide Research at Ambion has revealed startling differences in the signal sensitivities on Northern blots achieved by three methods of probe synthesis when using standard formamide or aqueous hybridization buffers random-priming of DNA, asymmetric PCR-generated DNA and in vitro.
