Using photoactivatable fluorescent protein Dendra2 to track protein movement

open access: yesBioTechniques, 2007
Photoactivatable fluorescent proteins are capable of dramatic changes in fluorescent properties in response to specific light irradiation. For example, they can be converted from cyan to green, or from green to red, or from nonfluorescent to a brightly ...

A Bright, Nontoxic, and Non-aggregating red Fluorescent Protein for Long-Term Labeling of Fine Structures in Neurons

open access: yesFrontiers in Cell and Developmental Biology, 2022
Red fluorescent proteins are useful as morphological markers in neurons, often complementing green fluorescent protein-based probes of neuronal activity. However, commonly used red fluorescent proteins show aggregation and toxicity in neurons or are dim.

Two-color in-resin CLEM of Epon-embedded cells using osmium resistant green and red fluorescent proteins

open access: yesScientific Reports, 2020
In-resin CLEM of Epon embedded samples can greatly simplify the correlation of fluorescent images with electron micrographs. The usefulness of this technique is limited at present by the low number of fluorescent proteins that resist CLEM processing ...

Photoactivation of green fluorescent protein [PDF]

open access: yesCurrent Biology, 1997
Considerable insight into many cell biological processes can be obtained by following the turnover of individual protein species in time and space. In living cells, this has been achieved by following fluorescence recovery after local microbeam photobleaching of microinjected fluorescently labelled protein (see, for example, [1xSpindle microtubule ...

Electrochemical fluorescence switching of enhanced green fluorescent protein

open access: yesBiosensors and Bioelectronics, 2023
Switchable fluorescent proteins, for which fluorescence can be switched ON and OFF, are widely used for molecule tracking and super resolution imaging. However, the robust use of the switchable fluorescent proteins is still limited as either the switching is not repeatable, or such switching requires irradiation with coupled lasers of different ...

Fluorophores for live cell imaging of AGT fusion proteins across the visible spectrum

open access: yesBioTechniques, 2006
O6-alkylguanine-DNA alkyltransferase (AGT) fusion proteins can be specifically and covalently labeled with fluorescent O6-benzylguanine (O6-BG) derivatives for multicolor live cell imaging approaches.

Imaging individual green fluorescent proteins [PDF]

open access: yesNature, 1997
Recent advances in fluorescence microscopy techniques have allowed the video-time imaging of single molecules of fluorescent dyes covalently bound to proteins in aqueous environments1. However, the techniques have not been exploited fully because proteins can be difficult to label, and dye modification may cause partial or complete loss of activity ...

Fluorescent proteins as tools to aid protein production

open access: yesMicrobial Cell Factories, 2005
Fluorescent proteins are genetically encoded, highly versatile reporters useful for monitoring various aspects of recombinant protein production. In addition to the widely popular green fluorescent protein (GFP) from Aequorea victoria, a variety of other
