gel electrophoresis principle and application

How Does 2D Gel Electrophoresis Work?

2D gel electrophoresis (2DE) is a key technique for purifying individual proteins from complex samples based on their isoelectric points and molecular weights Simple enough in theory but as the plethora of protocols and articles shows 2DE demands patience and meticulous optimization But whether your samples are human sera or HUVEC lysates 2DE uses these four core steps: sample

Southern Blotting

Southern Blotting Brief Introduction Blotting approaches are viewed as an aide to the gel electrophoresis which is generally applied for separation of DNA/RNA/protein and yields reproducible results attributed to their excellent resolving power Application Southern blotting is used in a number of applications

The principle applied was very simple: proteins were resolved on a gel using isoelectric focusing (IEF) which separates proteins in the first dimension according to their isoelectric point followed by electrophoresis in a second dimension in the presence of sodium dodecyl sulfate (SDS) which separates proteins according to their molecular mass O'Farrell's method is truly the basis of

Polyacrylamide gel electrophoresis

Agarose gel electrophoresis is a method of gel electrophoresis used in biochemistry molecular biology genetics and clinical chemistry to separate a mixed population of macromolecules such as DNA or proteins in a matrix of agarose one of the two main components of agar The proteins may be separated by charge and/or size and the DNA and RNA fragments by length

Rotating Gel Electrophoresis (RGE):In England in 1987 Southern (22) described a novel PFGE system that rotates the gel between two set angles while the electrodes are off In RGE the electric field is uniform and bands are straight because only one set of electrodes is used RGE makes it easy to perform time and voltage ramping It also enables users to study the effects of different angles

List of the Applications of Electrophoresis

Electrophoresis plays a number of roles in the testing of antibiotics One of the most common is testing the purity of an antibiotic By applying electrophoresis to a solution containing the antibiotic in the form of a paper strip impregnated with the antibiotic or a capillary – a very thin tube – filled with the solution researchers can differentiate between the antibiotic itself and any

History

Zone electrophoresis found widespread application in biochemistry after Oliver Smithies introduced starch gel as an electrophoretic substrate in 1955 Starch gel (and later polyacrylamide and other gels) enabled the efficient separation of proteins making it possible with relatively simple technology to analyze complex protein mixtures and identify minute differences in related proteins

What Are the Steps in Gel Electrophoresis?

Gel electrophoresis is a process of separating bio molecules of different sizes by running them through a sievelike matrix using electricity The larger molecules move more slowly while smaller molecules slip through the matrix and move faster and farther thus separating the different fragments based on size
