Please note that nitrocellulose membranes are chemically incompatible with the NorthernMax Transfer Buffer and should not be used with these kits. Compared to qPCR, the major limitations of Northern blot analysis are low detection sensitivity and easy RNA degradation by contaminated exogenous ribonucleases (RNases) in the course of extensive handling of RNA prior to blotting. 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. 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. Northern blotting analysis is a classical method for analysis of the size and steady-state level of a specific RNA in a complex sample. 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.

PureLink® Pro 96 Total RNA Purification Kit MELT™ Total Nucleic Acid Isolation System (A) Total RNA (0. 1 2 Whereas western blot uses an antibody probe to detect a protein of interest, far-western blot uses a non-antibody probe which can bind the protein of. Northern blotting is used as a sensitive test for the detection of transcription of DNA fragments that are to be used as a probe in Southern Blotting. MagMAX™-96 for Microarrays Total RNA Isolation Kit Immuno-northern blot analysis using the anti-m5C antibody with acrylamide and agarose gel separation. The far-western blot, or far-western blotting, is a molecular biological method based on the technique of western blot to detect protein-protein interaction in vitro. environmental contamination is possible at most stages of Northern-blot analysis, with fingers being a major source of contamination. RecoverAll™ Total Nucleic Acid Isolation Kit for FFPE An antibody to digoxigenin, conjugated with alkaline phosphatase, is used to detect hybridization of the digoxigenin-labelled oligonucleotide to the target mRNA.
