Los investigadores desarrollaron G-Ca-FLITS, un novedoso biosensore fluorescente verde para calcio. Este sensor mantiene un alto brillo en ambos estados, lo que permite mediciones precisas con una relación señal-ruido (SNR) estable en niveles de calcio variables.
Conclusiones:
- G-Ca-FLITS ofrece una herramienta robusta para mediciones cuantitativas de calcio, superando las limitaciones de SNR de los biosensore tradicionales.
- La estabilidad y el rendimiento del sensor lo hacen adecuado para diversas aplicaciones, incluida la obtención de imágenes de orgánulos y estudios in vivo.
- G-Ca-FLITS representa un avance significativo en la tecnología de detección de calcio.

Light as Energy
Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...

Protein Dynamics in Living Cells
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
