Examples of blot in the following topics:
-
- Northern blots allow investigators to determine messenger RNA molecular weight and sample content.
- The term 'Northern blot' actually refers specifically to the capillary transfer of RNA from the electrophoresis gel to the blotting membrane.
- However, the entire process is commonly referred to as Northern blotting.
- Northern blotting takes its name from its similarity to the first blotting technique, the Southern blot, named for biologist Edwin Southern.
- The major difference is that RNA, rather than DNA, is analyzed in the Northern blot.
-
- The Western blot technique determines protein molecular weight and measures protein abundance in different samples.
- Western blot samples can be taken from whole tissue or from cell culture.
- The name Western blot was given to the technique by W.
- Neal Burnette and is a play on the name Southern blot, a technique for DNA detection developed earlier by Edwin Southern.
- Detection of RNA is termed Northern blot.
-
- Immunoblot procedures like protein blotting, or Western blotting, allow individuals to detect specific solubilized proteins from extracts made from cells or tissues, before or after any purification steps.
- After this, they are transferred to a synthetic membrane via dry, semi-dry, or wet blotting methods.
- Western blotting is a routine molecular biology method that can be used to semi-quantitatively compare protein levels between extracts.
- proteins separated by molecular weight and represented by a dark band on a blot.
- Describe how Western blotting allows individuals to detect specific solubilized proteins from serum or cell or tissue extracts
-
- When DNA is transferred to a nylon membrane, the technique is called Southern blotting; when RNA is transferred to a nylon membrane, it is called northern blotting.
- Southern blots are used to detect the presence of certain DNA sequences in a given genome, and northern blots are used to detect gene expression.
- Southern blotting is used to find a particular sequence in a sample of DNA.
- Northern blotting is similar to Southern blotting, but RNA is run on the gel instead of DNA.
- In western blotting, proteins are run on a gel and detected using antibodies.
-
- Example of genetic analysis method using PCR and immobilized oligonucleotide probes: The reverse dot-blot method has several unique properties that are valuable in a diagnostic setting: (1) The typing that results from a single sample can be located on a single strip.
- This minimizes user labor as well as error potential and allows the use of standardized reagents. (3) Unlike dot-blot/oligonucleotide typing, only the PCR product is labeled, eliminating the potential problem of probes labeled to different specific activities.
- Spoligotyping, a reverse dot blot assay that detects the presence of a series of unique spacers in the direct repeat (DR) locus, meets the need for a simple and rapid method by which to distinguish M. tuberculosis complex strains.
-
- The western blot test and immuno dot blot tests detect the protein on a membrane.
-
- The western blot, or protein immunoblot, is a technique that combines protein electrophoresis and antibodies to detect proteins in a sample.
- A western blot is fairly quick and simple compared to the above techniques and, thus, can serve as an assay to validate results from other experiments.
-
- A similar hybridization technique is called a zoo blot.
-
- These tags are particularly useful for western blotting, immunofluorescence and immunoprecipitation experiments, although they also find use in antibody purification.
-
- A throat culture, for example, is taken by scraping the lining of tissue in the back of the throat and blotting the sample into a growing medium; this will allow analysis to screen for harmful microorganisms, such as Streptococcus pyogenes, the causative agent of strep throat.
