  1. Difference gel electrophoresis

    Difference gel electrophoresis DIGE is a form of gel electrophoresis where up to three different protein samples can be labeled with fluorescent dye s for example Cy3, Cy5, Cy2 prior to two dimensional electrophoresis. Then, the three samples are mixed and put in the same gel. After the gel electrophoresis, the gel is scanned with the excitation wavelength of each dye one after the other, so we are able to see each sample separately if we scan the gel at the excitation wavelength of the Cy3 dye, we will see in the gel only the sample that was labeled with that dye . This technique is used to see changes in protein abundance for example, between a sample of a healthy person and a sample of a person with disease . It overcomes limitations in traditional 2D electrophoresis that are due to inter gel variation. This can be considerable even with identical samples. Since the proteins from the different sample types e.g. healthy diseased, virulent non virulent are run on the same gel they can be directly compared. To do this with traditional 2D electrophoresis requires large numbers of time consuming repeats. In experiments comprising several gels, a common technique is to include an internal standard in each gel. The internal standard is prepared by mixing together several or all of the samples in the experiment. This allows the measurement of the abundance of a protein in each sample relative to the internal standard. Since the amounts of each protein in the internal standard is known to be the same in every gel, this method reduces inter gel variation. ref Alban, A., David, S. O., Bjorkesten, L., Andersson, C. et al.

    Pulsed field gel electrophoresis is a technique used for the separation of large DNA deoxyribonucleic acid DNA molecule s by applying an electric field that periodically changes direction to a gel matrix. Image Microbiologist 01.jpg right thumb 200px A microbiologist running a pulsed field gel electrophoresis test used in bacterial typing. Historical background Standard DNA electrophoresis gel electrophoresis techniques for separation of DNA molecules provided huge advantages for molecular biology research. However, it was unable to separate very large molecules of DNA effectively. DNA molecules larger than 15 20kb migrating through a gel will essentially move together in a size independent manner. At Columbia University in 1984, Schwartz and Charles Cantor Cantor developed a variation on the standard protocol by introducing an Alternating current alternating voltage gradient to improve the resolution of larger molecules. ref Schwartz DC, Cantor CR.

  1. Hemoglobin electrophoresis

    Unreferenced stub auto yes date December 2009 Hemoglobin electrophoresis is a blood test that can detect different types of hemoglobin . It uses the principles of gel electrophoresis to separate out the various types of hemoglobin and is a type of native gel electrophoresis . The test can detect abnormal levels of HbS, the form associated with sickle cell disease , as well as other abnormal hemoglobin related blood disorders, such as hemoglobin C . It can also be used to determine whether there is a deficiency of any normal form of hemoglobin, as in the group of diseases known as thalassemia s. Different hemoglobins have different charges, and according to those charges and the amount, hemoglobins move at different speeds in the gel whether in alkaline gel or acid gel.The hemoglobin electrophoresis is also known to be thalessemia screening, this also can be helpful for the patient who is frequently need of fresh blood transfusion. The patient needs blood transfusion because the body is unable to produce enough hemoglobin to satisfy the body s requirement. See Hemoglobinopathy Migration patterns Migration Patterns .

  1. Affinity electrophoresis

    unreferenced date September 2011 Affinity electrophoresis is a general name for many analytical methods used in biochemistry and biotechnology . Both qualitative and quantitative information may be obtained through affinity electrophoresis. The methods include the so called mobility shift electrophoresis, charge shift electrophoresis and affinity capillary electrophoresis . The methods are based on changes in the electrophoresis electrophoretic pattern of molecules mainly macromolecules through biospecific interaction or complex formation . The interaction or binding of a molecule, charged or uncharged, will normally change the electrophoretic properties of a molecule. Membrane proteins may be identified by a shift in mobility induced by a charged detergent . Nucleic acid s or nucleic acid fragments may be characterized by their affinity to other molecules. The methods has been used for estimation of binding constant s, as for instance in lectin affinity electrophoresis or characterization of molecules with specific features like glycan content or ligand binding. For enzymes and other ligand binding proteins, onedimensional electrophoresis similar to counter electrophoresis or to immunoelectrophoresis rocket immunoelectrophoresis , affinity electrophoresis may be used as an alternative quantification of the protein. Some of the methods are similar to affinity chromatography by use of immobilized ligands .

  1. Gel extraction

    In molecular biology , gel extraction or gel isolation is a technique used to isolate a desired fragment of intact DNA from an agarose gel following agarose gel electrophoresis . After extraction, fragments of interest can be mixed, precipitated, and enzymatically ligated together in several simple steps. This process, usually performed on plasmids , is the basis for rudimentary genetic engineering . After DNA samples are run on an agarose gel, extraction involves four basic steps identifying the fragments of interest, isolating the corresponding bands, isolating the DNA from those bands, and removing the accompanying salts and stain. To begin, UV light is shone on the gel in order to illuminate all the ethidium bromide stained DNA. Care must be taken to avoid exposing the DNA to mutagenic radiation for longer than absolutely necessary. The desired band is identified and physically removed with a cover slip or razor blade .
