Nucleic Acid Detection on Gels, Blots and Arrays—Section 8.4
SYBR Gold nucleic acid staining is compatible with both northern and Southern blotting—the stain transfers with the DNA or RNA to the blot and is washed off during incubation in the prehybridization mix.
Northern blot - Wikipedia
Northern blotting involves the use of electrophoresis to separate RNA samples by size, and detection with a hybridization probe complementary to part of or the entire target sequence. Strictly speaking, the term 'northern blot' refers specifically to the capillary transfer of RNA from the electrophoresis gel to the blotting membrane.
Through the Northern blotting process, we can determine both the levels and size of specific RNA in a sample providing insight into novel genes and their function. Variances in blots also allow for the discovery of transcription errors.
GelRed® Nucleic Acid Gel Stain - Biotium
Ultra sensitive and environmentally safe replacement for EtBr DNA/RNA gel stain. GelRed® is an ultra sensitive, extremely stable and environmentally safe fluorescent nucleic acid dye designed to replace the highly toxic ethidium bromide (EtBr) for staining dsDNA, ssDNA or RNA in agarose gels or polyacrylamide gels.
Northern Blot- Definition, Principle, Steps, Results, Applications
2021年6月4日 · Northern blot is a technique based on the principle of blotting for the analysis of specific RNA in a complex mixture. The technique is a modified version of the Southern Blotting, which was discovered for the analysis of DNA sequences.
Northern blot - PMC
Northern blot first uses denaturing gel to separate RNA according to the size. The RNA is then transferred to a nylon membrane while keeping the same distribution in the gel. After fixing the RNA to the membrane, labeled probe complementary to the gene of interest is then added to hybridize to the immobilized RNA.
Northern Blot - an overview | ScienceDirect Topics
Northern blotting is a hybridization-based technique where isolated RNA is separated by gel electrophoresis, transferred to a membrane, and detected by hybridization with a DNA or RNA probe. The first detection methods involved radioactive probes.
An Overview of Northern blot - GoldBio
Northern blot is a molecular biology technique used to detect levels of RNA molecules of a specific sequence in your sample. This method is useful for monitoring the transcription and transcript abundance of a target gene in a cell or tissue …

2024年11月23日 · The Northern blot is a technique used in molecular biology research to study gene expression in a sample, through detection of RNA (or isolated messenger RNA ). With Northern blotting it is possible to observe cellular control over structure and function by determining the particular gene expression levels during differentiation, morphogenesis ...
Northern & Southern Blot Protocols - MilliporeSigma
Fragments of DNA and RNA molecules separated by gel electrophoresis are transferred to a nylon or nitrocellulose membrane in a process termed as Southern and Northern blotting, respectively. Southern blotting was introduced by Edwin Southern in 1975 as a method to detect specific sequences of DNA in DNA samples.
