  2. Photoactivatable fluorescent protein - Wikipedia

    en.wikipedia.org/wiki/Photoactivatable...

    The first PAFP, Kaede (protein), was isolated from Trachyphyllia geoffroyi in a cDNA library screen designed to identify new fluorescent proteins. [1] A fluorescent green protein derived from this screen was serendipitously discovered to have sensitivity to ultraviolet light-- We happened to leave one of the protein aliquots on the laboratory ...

  3. Fluorescent tag - Wikipedia

    en.wikipedia.org/wiki/Fluorescent_tag

    Of the various methods of labeling biomolecules, fluorescent labels are advantageous in that they are highly sensitive even at low concentration and non-destructive to the target molecule folding and function. [1] Green fluorescent protein is a naturally occurring fluorescent protein from the jellyfish Aequorea victoria that is widely used to ...

  4. Eos (protein) - Wikipedia

    en.wikipedia.org/wiki/Eos_(protein)

    While the use of fluorescent proteins was once limited to the green fluorescent protein , in recent years many other fluorescent proteins have been cloned. Unlike GFPs, which are derived from the luminescent jellyfish Aequorea victoria, fluorescent proteins derived from anthozoa , including Eos, emit fluorescence in the red spectral range.

  5. Dronpa - Wikipedia

    en.wikipedia.org/wiki/Dronpa

    An animation of the structure of the dark state of dronpa protein Dronpa is a reversibly switchable photoactivatable fluorescent protein that is 2.5 times as bright as EGFP . [ 1 ] [ 2 ] Dronpa gets switched off by strong illumination with 488 nm (blue) light and this can be reversed by weak 405 nm UV light. [ 1 ]

  6. Fluorescence-activating and absorption-shifting tag - Wikipedia

    en.wikipedia.org/wiki/Fluorescence-Activating...

    The FAST-fluorogen reporting system is used to explore the living world, from protein reporting (e.g., for protein trafficking), protein-protein interaction monitoring (and a number of biosensors), to chemically induced dimerization. It is implemented in fluorescence microscopy, flow cytometry and any other fluorometric methods.

  7. Photoactivatable probes - Wikipedia

    en.wikipedia.org/wiki/Photoactivatable_probes

    Photoactivatable fluorescent proteins change to longer emission wavelength upon illumination with UV light. In Kaede, this change is brought upon by cleavage of the chromophore tripeptide His62-Tyr63-Gly64. [5] This discovery paved the way for modern super resolution microscopy techniques like PALM or STORM. Retinylidene proteins, such as ...

  8. Fluorescence in the life sciences - Wikipedia

    en.wikipedia.org/wiki/Fluorescence_in_the_life...

    Some proteins or small molecules in cells are naturally fluorescent, which is called intrinsic fluorescence or autofluorescence (such as NADH, tryptophan or endogenous chlorophyll, phycoerythrin or green fluorescent protein). The intrinsic DNA fluorescence is very weak [1].Alternatively, specific or general proteins, nucleic acids, lipids or ...

  9. Fluorophore - Wikipedia

    en.wikipedia.org/wiki/Fluorophore

    StayGold and mStayGold are advanced fluorescent proteins that have significantly contributed to the field of live-cell imaging. StayGold, known for its high photostability and brightness, was originally designed as a dimeric fluorescent protein, which, while effective, posed challenges related to the aggregation and labelling accuracy.
