A blot, in molecular biology and genetics, is a method of transferring proteins, DNA or RNA, onto a carrier (for example, a nitrocellulose PVDF or nylon membrane). In many instances, this is done after a gel electrophoresis, transferring the molecules from the gel onto the blotting membrane, and other times adding the samples directly onto the membrane. After the blotting, the transferred proteins, DNA or RNA are then visualized by colorant staining (for example, silver staining of proteins), autoradiographic visualization of radioactive labelled molecules (performed before the blot), or specific labelling of some proteins or nucleic acids. The latter is done with antibodies or hybridization probes that bind only to some molecules of the blot and have an enzyme joined to them. After proper washing, this enzymatic activity (and so, the molecules we search in the blot) is visualized by incubation with proper reactive, rendering either a colored deposit on the blot or a chemiluminiscent reaction which is registered by photographic film.
Blót ( Old Norse neuter) was a Norse pagan sacrifice to the Norse gods and the spirits of the land. The sacrifice often took the form of a sacramental meal or feast. Related religious practices were performed by other Germanic peoples, such as the pagan Anglo-Saxons. The blót element of horse sacrifice is found throughout Indo-European traditions, including the Indian, Celtic and Latin traditions.
Blot is the fourth full-length album by the Norwegian black/ Viking metal band Einherjer. It was released on November 21, 2003, by Tabu Recordings.
