  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. 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 ]

  4. 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.

  5. 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. [ 15 ]

  6. 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.

  7. Kaede (protein) - Wikipedia

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

    As all other fluorescent proteins, Kaede can be the regional optical markers for gene expression and protein labeling for the study of cell behaviors. [3] One of the most useful applications is the visualization of neurons. Delineation of an individual neuron is difficult due to the long and thin processes which entangle with other neurons.

  8. 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 ...

  9. Photoswitch - Wikipedia

    en.wikipedia.org/wiki/Photoswitch

    Photoswitchable Molecules: Upon irradiation with light, photoisomerization occurs, changing the spatial geometry and properties of the molecule. Photoswitchable Molecules : Azobenzene undergoes a E to Z photoisomerization in which the Z isomer is more polar, has shorter bonds, and a bent and twisted geometry. [ 4 ]
