An example Gel documentation system, showing the results of gel electrophoresis on a connected monitor.. A gel doc, also known as a gel documentation system, gel image system or gel imager, refers to equipment widely used in molecular biology laboratories for the imaging and documentation of nucleic acid and protein suspended within polyacrylamide or agarose gels.
Articles in economics journals are usually classified according to JEL classification codes, which derive from the Journal of Economic Literature.The JEL is published quarterly by the American Economic Association (AEA) and contains survey articles and information on recently published books and dissertations.
[4] [3] In figure 5, several related terms and symbols are shown. Focal length (f) refers to the elevation difference between the film and the lens. [2] [4] H is the elevation difference between the lens and the sea level, which is the average level of the water surface. [2] [4] h is the elevation difference between the terrain surface and the ...
A common protocol used in the past for zymography of α-amylase activity was the so-called starch film protocol of W.W. Doane. Here a native PAGE gel was run to separate the proteins in a homogenate. Subsequently, a thin gel with starch dissolved (or more properly, suspended) in it was overlaid for a period of time on top of the original gel. [6]
[1] Agarose as 1% gel slabs of about 1 mm thickness buffered at high pH (around 8.6) is traditionally preferred for electrophoresis and the reaction with antibodies. The agarose was chosen as the gel matrix because it has large pores allowing free passage and separation of proteins but provides an anchor for the immunoprecipitates of protein ...
Isoelectric focusing can resolve proteins that differ in pI value by as little as 0.01. [4] Isoelectric focusing is the first step in two-dimensional gel electrophoresis, in which proteins are first separated by their pI value and then further separated by molecular weight through SDS-PAGE.
A man who wakes up after having a migraine discovers he can read the minds of animals. 112. A secret society of mermaids is trying to stay hidden despite scuba divers recently almost seeing them.
A caption may be a few words or several sentences. Writing good captions takes effort; along with the lead and section headings, captions are the most commonly read words in an article, so they should be succinct and informative. Not every image needs a caption; some are simply decorative. Relatively few may be genuinely self-explanatory.
