RESERVE THIS MICROSCOPE
The microscope is configured for simultaneous, two channel fast imaging with added capabilities for ROI photo-activation, FRAP, FRET and TIRF. This imaging system is specialized for fast imaging of live cells.
System specifications:
- Nikon TiE inverted microscope with Perfect Focus (PFS) mechanism
- Motorized XY Stage, allowing large images and multi-point time-lapse imaging
- Yokogawa CSU-X1 (1,800 rpm, 360 fps)/Borealis Upgrade/405/488/561/642 multichroic
- fast piezo Z stage (100 um travel, 15 ms step response)
- Mosaic digital illumination/bleaching/activation system (450 mW 405nm laser)
- Nikon motorized TIRF illuminator
- InVivo Scientific enclosure w/ environmental control (temperature and CO2)
- Possibility to image 2 colors simultaneously with up to 56 frames/sec with 512 x 512 pixels and no binning

What to put in Material and Methods section (example for SDC):
Cells were cultivated in tissue culture dish with No. 1.5 cover glass bottom (FluoroDish) and mounted in an environmental chamber (in vivo scientific) for acquisition at 37°C and 5% CO2. DMEM media with 25mM Hepes (pH 7.2) and without phenol red was used during image acquisition, with a layer of mineral oil on top of the media to prevent evaporation. All image were collected with a Yokogawa spinning disk confocal on a Nikon Eclipse-TI inverted microscope (Nikon) equipped with a PLAN APO-TIRF 100X 1.49 N.A. oil immersion objective and the Perfect Focus System for continuous maintenance of focus. XX-EGFP fluorescence was excited with the 488nm line from a 50mW Cobolt Blues laser and collected with a quadruple band pass dichroic mirror (Semrock) and a 525/30 emission filter (Semrock). Images were acquired with an Andor iXon Ultra 897 EMCCD camera controlled with NiS-Elements software. For timelapse experiments, images were collected every 1 min, using an exposure time of 500 ms and 2x2 binning, with illumination light shuttered between acquisitions. At each time point, 6 z-series optical sections were collected with a step size of 0.5 microns, using a piezo Z-axis stage (Mad City Labs). ZGamma, brightness, and contrast were adjusted on displayed images (identically for compared image sets) using NIS-Elements software.
