![]() ![]() 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. 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. Northern analysis provides a direct relative comparison of message abundance between samples on a single membrane. Transfer to Solid Support and Immobilization The Basics: Northern Analysis Northern analysis remains a standard method for detection and quantitation of mRNA levels despite the advent of powerful techniques, such as RT-PCR, gene array analysis and nuclease protection assays. View our RNA Isolation Kit Selection Guide probes in northern blot analysis as different haptens like digoxigenin. TRIzol® Max™ Bacteria/Yeastl RNA Isolation Kit (4) Highlighted the use of specific antibodies for binding of a specific. The 8 to 10-fold increase in sensitivity provided by switching to an. ![]() This fact has been recognized in the literature (1, 2, 3), by other manufacturers of labeling and detection kits, and by data generated here at Ambion. PureLink® Pro 96 Viral RNA/DNA Purification Kit Using RNA probes in Northern analyses results in significantly greater sensitivity as compared to double-stranded DNA probes. ![]() PureLink® Pro 96 Total RNA Purification Kit Mapping of transcribed mRNA and protein coding sequences is the initial step in functional characterization of genomic sequences. MELT™ Total Nucleic Acid Isolation System Principle: The commonly used detection methods involve the use of protein-specific primary antibody followed by detection using secondary antibodies conjugated with either HRP (horseradish peroxidase) or AP (alkaline phosphatase) enzyme. In this technique a mixture of proteins is separated based on molecular weight, and thus by type, through gel electrophoresis. MagMAX™-96 for Microarrays Total RNA Isolation Kit The membrane is exposed to an antibody specific to the target. The separated proteins are transferred out of the gel to the surface of a membrane. The method involves using gel electrophoresis to separate the samples proteins. RecoverAll™ Total Nucleic Acid Isolation Kit for FFPE Western blotting is a laboratory technique used to detect a specific protein in a blood or tissue sample. ![]()
