The Stentoften Stone, bearing a runic inscription that likely describes a blót of nine he-goats and nine male horses bringing fertility to the land. [1]Blót (Old Norse and Old English) or geblÅt (Old English) are religious ceremonies in Germanic paganism that centred on the killing and offering of an animal to a particular being, typically followed by the communal cooking and eating of its ...
Blotting Compass. In molecular biology and genetics, a blot is a method of transferring large biomolecules (proteins, DNA or RNA) onto a carrier, such as a membrane composed of nitrocellulose, polyvinylidene fluoride or nylon.
A blotting matrix, in molecular biology and genetics, is the substrate onto which macromolecules, such as proteins, are transferred in a blot method. [1] The matrices are generally chemically modified paper filters or microporous membrane filters. In a dot blot, macromolecules are applied directly to the
The western blot method is composed of gel electrophoresis to separate native proteins by 3-D structure or denatured proteins by the length of the polypeptide, followed by an electrophoretic transfer onto a membrane (mostly PVDF or nitrocellulose) and an immunostaining procedure to visualize a certain protein on the blot membrane.
The southwestern blot, is a lab technique that involves identifying as well as characterizing DNA-binding proteins [1] by their ability to bind to specific oligonucleotide probes. Determination of molecular weight of proteins binding to DNA is also made possible by the technique.
The eastern blot, or eastern blotting, is a biochemical technique used to analyze protein post-translational modifications including the addition of lipids, phosphates, and glycoconjugates. It is most often used to detect carbohydrate epitopes. Thus, eastern blot can be considered an extension of the biochemical technique of western blot.
Typical dot blot membrane. Darker dots indicate more protein. A dot blot (or slot blot) is a technique in molecular biology used to detect proteins. It represents a simplification of the western blot method, with the exception that the proteins to be detected are not first separated by electrophoresis. Instead, the sample is applied directly on ...
The northern blot, or RNA blot, [1] is a technique used in molecular biology research to study gene expression by detection of RNA (or isolated mRNA) in a sample. [ 2 ] [ 3 ] With northern blotting it is possible to observe cellular control over structure and function by determining the particular gene expression rates during differentiation ...
