  2. Fluorescent tag - Wikipedia

    en.wikipedia.org/wiki/Fluorescent_tag

    S. cerevisiae septins revealed with fluorescent microscopy utilizing fluorescent labeling. In molecular biology and biotechnology, a fluorescent tag, also known as a fluorescent label or fluorescent probe, is a molecule that is attached chemically to aid in the detection of a biomolecule such as a protein, antibody, or amino acid.

  3. Molecular-weight size marker - Wikipedia

    en.wikipedia.org/wiki/Molecular-weight_size_marker

    A molecular-weight size marker, also referred to as a protein ladder, DNA ladder, or RNA ladder, is a set of standards that are used to identify the approximate size of a molecule run on a gel during electrophoresis, using the principle that molecular weight is inversely proportional to migration rate through a gel matrix.

  4. Electrophoretic color marker - Wikipedia

    en.wikipedia.org/wiki/Electrophoretic_color_marker

    An electrophoretic color marker is a chemical used to monitor the progress of agarose gel electrophoresis and polyacrylamide gel electrophoresis (PAGE) since DNA, RNA, and most proteins are colourless. [1] The color markers are made up of a mixture of dyes that migrate through the gel matrix alongside the sample of interest. They are typically ...

  5. Immunoassay - Wikipedia

    en.wikipedia.org/wiki/Immunoassay

    Possibly one of the most popular labels to use in immunoassays is enzymes. Immunoassays which employ enzymes are referred to as enzyme immunoassays (EIAs), of which enzyme-linked immunosorbent assays (ELISAs) and enzyme multiplied immunoassay technique (EMIT) are the most common types.

  6. Restriction site associated DNA markers - Wikipedia

    en.wikipedia.org/wiki/Restriction_site...

    The use of RAD markers for genetic mapping is often called RAD mapping. An important aspect of RAD markers and mapping is the process of isolating RAD tags, which are the DNA sequences that immediately flank each instance of a particular restriction site of a restriction enzyme throughout the genome. [1]

  7. Molecular marker - Wikipedia

    en.wikipedia.org/wiki/Molecular_marker

    Genomic markers as mentioned, have particular strengths and weakness, so, consideration and knowledge of the markers is necessary before use. For instance, a RAPD marker is dominant (identifying only one band of distinction) and it may be sensitive to reproducible results. This is typically due to the conditions in which it was produced.

  8. Immunostaining - Wikipedia

    en.wikipedia.org/wiki/Immunostaining

    The primary antibody can be directly labeled using an enzyme or fluorophore. The primary antibody can be labeled using a small molecule which interacts with a high affinity binding partner that can be linked to an enzyme or fluorophore. The biotin-streptavidin is one commonly used high affinity interaction.

  9. Biomarker (medicine) - Wikipedia

    en.wikipedia.org/wiki/Biomarker_(medicine)

    In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. It may be defined as a "cellular, biochemical or molecular alteration in cells, tissues or fluids that can be measured and evaluated to indicate normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention."
