Electrophoresis can be defined as the mobilization of electrically charged matter in the existence of an electric field.
This is credited to the Coulomb force that in turn is in association with the electrical conditions. Molecular biology
makes use of gel electrophoresis. This is a process commonly used for nucleic acid like DNA and RNA isolation. It engages the loading of DNA, RNA and other proteins on a gel that reduces molecular mobility. This method isolates them, based on their electrophoretic mobility. The most frequently used is the fragile, big pored colloid, agarose gel, whose molecular mass is almost 12,000.
Agarose is a linear polysaccharide isolated from seaweed and is damaged on handling. It is used mainly to detach large molecules of a molecular mass larger than 200 k dal.
Although agarose gels get faster results, their promise is inferior because of the unmanageable pore size. It includes agarobiose in a repeated manner that has galactose and 3,6-anhydrogalactose in an swapping manner. It is frequently used at around one percent to three percent.
Grounded on the frictional forces and charges capillary electrophoresis or CE is used to separate ionic species.
This technique involves the utilization of fused silica capillaries to isolate a complex range of molecules, involving big and small. The capillary tube radiates heat freely and thus over heating of samples is barred. Molecules are separately based on their charge, water repelling qualities and size. An assortment of separation methods are followed including
- Non-Aqueous Capillary Electrophoresis (NACE)
- Capillary Gel Electrophoresis (CGE)
- Isotachophoresis (ITP)
- Electrokinetic Chromatography (EKC)
- Capillary Isoelectric Focusing (CIEF)
- Capillary Zone Electrophoresis (CZE)
- Micro Emulsion Electrokinetic Chromatography (MEEKC)
- Capillary Electrochromatography (CEC)
Diseases in humans are diagnosed by recognizing particular proteins in the blood and this technique is referred to as Serum Protein Electrophoresis or SPE. This process diagnoses amyloidosis and myeloma. Amino acids form proteins that act as a carrier for the + ve and - ve electrical charge and they rally in fluid in the existence of an electrical field. An electrical field is necessary to segregate the serum proteins, based on their shape, charge and size. It is a globulin specific test. It is a laboratory process where blood sample is collected in a sterile syringe. A special paper with agarose gel is taken and the serum is kept over it and placed in an electrical field. It diagnoses hypo-gammaglobulinemia, a disorder attributed to decreased gamma globulin levels. These people are more susceptible to infection.
In this process that is based on the electrical charge, serum proteins are in addition classified into globulin, alpha 2 globulin, albumin alpha1, beta globulin and gamma globulin.
