  2. Gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Gel_electrophoresis

    The graph to the right shows the nonlinear relationship between the size of the DNA fragment and the distance migrated. Gel electrophoresis is a process where an electric current is applied to DNA samples creating fragments that can be used for comparison between DNA samples. DNA is extracted. Isolation and amplification of DNA.

  3. Nirenberg and Matthaei experiment - Wikipedia

    en.wikipedia.org/wiki/Nirenberg_and_Matthaei...

    In 1953, with the help of Maurice Wilkins and Rosalind Franklin's X-ray crystallography, James Watson and Francis Crick proposed DNA is structured as a double helix. [1] In the 1960s, one main DNA mystery scientists needed to figure out was the number of bases found in each code word, or codon, during transcription.

  4. SDS-PAGE - Wikipedia

    en.wikipedia.org/wiki/SDS-PAGE

    Proteins of the erythrocyte membrane separated by SDS-PAGE according to their molecular masses. SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K. Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa.

  5. Polyacrylamide gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Polyacrylamide_gel...

    Picture of an SDS-PAGE. The molecular markers (ladder) are in the left lane. Polyacrylamide gel electrophoresis (PAGE) is a technique widely used in biochemistry, forensic chemistry, genetics, molecular biology and biotechnology to separate biological macromolecules, usually proteins or nucleic acids, according to their electrophoretic mobility.

  6. Methods to investigate protein–protein interactions - Wikipedia

    en.wikipedia.org/wiki/Methods_to_investigate...

    This could include bridging proteins, nucleic acids (DNA or RNA), or other molecules. Bimolecular fluorescence complementation (BiFC) is a new technique in observing the interactions of proteins. Combining with other new techniques, this method can be used to screen proteinprotein interactions and their modulators, [3] DERB. [4]

  7. Proteomics - Wikipedia

    en.wikipedia.org/wiki/Proteomics

    Proteomics generally denotes the large-scale experimental analysis of proteins and proteomes, but often refers specifically to protein purification and mass spectrometry. Indeed, mass spectrometry is the most powerful method for analysis of proteomes, both in large samples composed of millions of cells [5] and in single cells. [6] [7]

  8. Western blot - Wikipedia

    en.wikipedia.org/wiki/Western_blot

    The relationship between protein function and localization suggests that when proteins move, their functions may change or acquire new characteristics. A protein's subcellular placement can be determined using a variety of methods.

  9. Gel electrophoresis of proteins - Wikipedia

    en.wikipedia.org/.../Gel_electrophoresis_of_proteins

    SDS is a strong detergent agent used to denature native proteins to unfolded, individual polypeptides. When a protein mixture is heated to 100 °C in presence of SDS, the detergent wraps around the polypeptide backbone. In this process, the intrinsic charges of polypeptides becomes negligible when compared to the negative charges contributed by ...
