Northern blot原理图
The northern blot, or RNA blot, is a technique used in molecular biology research to study gene expression by detection of RNA (or isolated mRNA) in a sample. With northern blotting it is possible to observe cellular control over structure and function by determining the particular gene expression rates … Ver mais A general blotting procedure starts with extraction of total RNA from a homogenized tissue sample or from cells. Eukaryotic mRNA can then be isolated through the use of oligo (dT) cellulose chromatography to … Ver mais Northern blotting allows one to observe a particular gene's expression pattern between tissues, organs, developmental stages, environmental stress levels, pathogen infection, and over the course of treatment. The technique has been used to show … Ver mais • Western blot • Eastern blot • Northwestern blot • Far-eastern blot Ver mais Analysis of gene expression can be done by several different methods including RT-PCR, RNase protection assays, microarrays, Ver mais Researchers occasionally use a variant of the procedure known as the reverse northern blot. In this procedure, the substrate nucleic acid (that is affixed to the membrane) is a collection of isolated DNA fragments, and the probe is RNA extracted from a tissue and … Ver mais Web22 de abr. de 2011 · See more video protocols, please visit http://www.video-protocols.comThe northern blot is a technique used in molecular biology research to study gene expres...
