How Do You Spell ELECTROPHORETIC MOBILITY SHIFT ASSAY?

Pronunciation: [ɪlˌɛktɹə͡ʊfɔːɹˈɛtɪk mə͡ʊbˈɪlɪti ʃˈɪft ɐsˈe͡ɪ] (IPA)

The Electrophoretic Mobility Shift Assay is a widely used technique in molecular biology, which helps in analyzing protein-DNA interactions. The spelling of the word "Electrophoretic Mobility Shift Assay" can be explained using the IPA phonetic transcription system as follows- /əˌlɛktrəʊfəˈrɛtɪk məʊˈbɪlɪti ʃɪft əˈseɪ/. The word is formed by combining three main terms, "electrophoretic," "mobility shift," and "assay." Therefore, the spelling of the word reflects its elements, and the IPA transcription helps in pronouncing the word correctly.

ELECTROPHORETIC MOBILITY SHIFT ASSAY Meaning and Definition

  1. The Electrophoretic Mobility Shift Assay (EMSA) is a biochemical technique used to study protein-DNA interactions. This assay is commonly used to investigate the binding of transcription factors or other DNA-binding proteins to specific DNA sequences.

    In an EMSA, a short, labeled DNA fragment is generated that represents the DNA sequence of interest. This fragment is mixed with the protein of interest and incubated together. The mixture is then subjected to gel electrophoresis, which separates the DNA-protein complexes from unbound DNA fragments based on their size and charge. The gel is typically a polyacrylamide gel, which is chosen for its high resolution capability.

    When the gel is run, DNA-protein complexes migrate through the gel at a slower rate compared to unbound DNA fragments due to their larger size or altered charge. This change in mobility, or shift, is the key feature of this assay. By visualizing the gel using autoradiography or fluorescence, the presence of DNA-protein complexes can be determined.

    EMSA provides qualitative and quantitative information about protein-DNA interactions, including affinity, specificity, and binding kinetics. It can also help identify potential DNA-binding proteins in complex mixtures. Additionally, EMSA can be used to investigate the effects of mutations or chemical modifications on protein-DNA interactions.

    Overall, the Electrophoretic Mobility Shift Assay is a powerful technique for studying and characterizing protein-DNA interactions and is widely used in molecular biology and genetics research.
