The x-y image of actin filaments of living HeLa cells in 3DSIM mode for two-photon activation
Description
An x-y image of actin filaments in living HeLa cells visualized with rsGamillus-S was obtained using selective-plane-activation structured illumination microscopy (SPA-SIM) with two-photon activation and a scanned Bessel beam. rsGamillus-S is an acid-resistance photoswitchable fluorescent protein, which owns exceptionally high on-switching rate to show the nuclei more clearly. Two-photon activation using a scanned Bessel beam produces a wider FOV and a higher axial resolution.
