Analysis of intracellular protein dynamics in living zebrafish embryos using light-sheet fluorescence single-molecule microscopy

Abstract: Single-molecule microscopy techniques have emerged as useful tools to image individual molecules and analyze their dynamics inside cells, but their application has mostly been restricted to cell cultures. Here, a light-sheet fluorescence microscopy setup is presented for imaging individual proteins inside living zebrafish embryos. The optical configuration makes this design accessible to many laboratories and a dedicated sample-mounting system ensures sample viability and mounting flexibility. Using this setup… Show more

“…This has led to researchers utilizing light sheet microscopy to study dynamic cellular processes over a few hours to days, including events such as embryo development and morphogenesis in an array of species [12][13][14][15][16][17] . Further, light sheet microscopy has been used to observe dynamic changes in microtubules 18 , intracellular proteins 19 , and embryo metabolism 10 . Measurement of autofluorescence is not without its unique set of challenges: in particular, the signal may exhibit relatively weak intensity 4 .…”

“…SMM is predominantly performed using advanced fluorescence microscopy approaches that include, among others, total internal reflection fluorescence (TIRF), highly-inclined and laminated optical sheet (HILO), and light-sheet fluorescence microscopy (LSFM) (e.g. Bernardello et al, 2021; Lommerse et al, 2006; Miller et al, 2018; Schaaf et al, 2009; Shashkova and Leake, 2017). Microscopy setups designed for imaging of individual fluorescent molecules are generally equipped with a laser beam used to excite fluorophores, and with a highly sensitive charged-couple device (CCD) or a complementary metal-oxide-semiconductor (CMOS) camera for efficient recording of the emitted photons (Axelrod, 2001).…”
