Capillary electrophoresis (CE) is a family of electrokinetic separation methods performed in submillimeter diameter capillaries and in micro- and nanofluidic channels.Very often, CE refers to capillary zone electrophoresis (CZE), but other electrophoretic techniques including capillary gel electrophoresis (CGE), capillary isoelectric focusing (CIEF), capillary isotachophoresis and micellar ...
The data is plotted with time, shown via base pairs (bps), on the x-axis and fluorescence intensity on the y-axis. Such plots are often achieved using an instrument such as an automated DNA sequencer paired with capillary electrophoresis (CE). Such electropherograms may be used to determine DNA sequence genotypes, or genotypes that are based on ...
The drawing of the electrophoretic bands provided by the laboratory may be difficult to remember, and medical students, residents, nurses, and non-specialized medical practitioners may find visual mnemonics useful to recall the five main bands and the shape of normal serum electrophoresis. [5]
Indeed, the separations following heating to 50 °C tend to exhibit a substantial increase in band resolution, without appreciable loss of activity. [ 4 ] [ 5 ] A common protocol used in the past for zymography of α-amylase activity was the so-called starch film protocol of W.W. Doane.
[1] [2] Capillary electrochromatography is a combination of two analytical techniques, high-performance liquid chromatography and capillary electrophoresis. Capillary electrophoresis aims to separate analytes on the basis of their mass-to-charge ratio by passing a high voltage across ends of a capillary tube , which is filled with the analyte.
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.
Capillary electrochromatography (CEC) is an electrochromatography technique in which the liquid mobile phase is driven through a capillary containing the chromatographic stationary phase by electroosmosis. [3] [4] It is a combination of high-performance liquid chromatography and capillary electrophoresis. The capillaries is packed with HPLC ...
A probe that hybridizes only to a single DNA segment that has not been cut by the restriction enzyme will produce a single band on a Southern blot, whereas multiple bands will likely be observed when the probe hybridizes to several highly similar sequences (e.g., those that may be the result of sequence duplication).
