Microscope Reference Transmitted Light Imaging Turn ON X-Cite 120 UV lamp The green switch located on the right side of the microscope base indicates both Microscope power and halogen power. Note: For Fluorescence imaging: Check the Reflector turret is set to desired excitation/emission OPEN the Halogen lamp shutter through software by selecting Extra Shutter 1 to allow light to the sample. • Zeiss Reflector Turret set to: (1) 350EX/460EM DAPI (2) 470EX/515EM FITC (3) 560EX/620EM Rhodamine (4) C5 640EX/680EM Cy5 Set the Zeiss Reflector Turret to position (5) DIC. Fluorescent Imaging • Cycle Fluor Key to allow light to sample. The microscope is configured so the condenser will change to DIC/Phase contrast depending on the objective chosen. This can be overridden in the software. Specific settings can be saved using the Tools > Settings Editor. Load a sample and find focus... Align Optical Components lumination (see next page). 1. Load a sample. Tilt the lamp carrier back to allow access to the stage. Lower the objective lens by pressing the Focus Load Key (7) on lower right of microscope stand. Rotate the preferred objective lens into position beneath the stage using the Objective Keys Forward - Backward (8). Load your sample. Select the Focus Work Key (9) and the scope will raise the objective back to the last highest position it was in before it was lowered. • The contrast or “shear” may be adjusted by manipulating the small knob on the Wollaston Prism located just below the objective lens. For phase contrast microscopy [currently only the 10x or 20x objectives]: • Rotate the condenser wheel to the appropriate setting : 10x = Ph 1; 40x =Ph 2. • Swing OUT the polarizer located between the condenser and the lamp. 2. Select eyes from the Toolbar to direct the light path to the eyepieces. Also, make sure that the Black Rotary Knob under the Binocular Tubes is set to 100% vis. • Align the microscope for Koehler Illumination. 3. Select Imaging Method: For widefield fluorescence viewing: • Choose the appropriate excitation and emission filters for sample. • Adjust the Incident Iris Stop Slider until light Intensity is adequate. • Find Focus. For conventional brightfield viewing: • Rotate the condenser wheel (4) to the BF position as indicated on the LCD on the scope. (Right side buttons) Optical Components Zeiss Axiovert 200M For Nomarski differential-interference contrast microscopy (DIC): • DIC objectives automatically change the condenser wheel to the appropriate DIC setting for their numerical aperture. (The appropriate condenser setting is determined by the numerical aperture of the objective —see the quick notes.) • Swing OUT the polarizer located between the condenser and the lamp. • The analyzer is built into the No Filter (DIC) filter cube in the Zeiss Reflector Turret. • Align the microscope for Koehler Illumination. • Swing the polarizer into place between the condenser and the lamp.

Focus on specimen with the objective to be used for data collection. 2. Close down lamp field stop [diaphragm at top (1) ] while viewing. 3. Lower condenser slightly (2) until diaphragm image is in focus. 4. Center image using condenser centering screws (3). 5. Open diaphragm (1) to edge of field, fine focus and open further to just clear field. 6. Adjust contrast using condenser diaphragm (4). 7. Remove eyepiece (5) and check to see that 75%-80% of visible aperture is filled with light (more light=better resolution but less contrast).

Dropping the camera resolution to 8bit helps to acquire larger areas with higher magnification objectives. Saving files Quick Notes Present Spatial Calibration: Data is saved by selecting the ‘Save As’ button at the top left corner of the AxioVision interface, or by selecting File > Save or File > Save As. Zeiss organizes files two ways: either as a single “Experiment-name file” with a “*.zvi” extension or as an experimentname folder with grouped “Experiment-name *.zvi files” inside. Files created with MosaiX and Time Series can get quite large so default saves and acquisitions are set to save to the local machine. 1. Save to Local Machine. --Default You may save files to Workspace (E:\Workspace\”username”). A folder was created there at login for each user. 2.

Most users opt to save the data to their network share on our central server (named Zeus). The server share is represented as the ‘Z:\’ drive in the windows environment. ITG is equipped with gigabit ethernet, and saving to the Z:\ drive is relatively fast. Also, this permits easy access to the data from any computer in the world using secure file transfer protocol (sftp).

The position in the dataset to which an image belongs is encoded into the name, thus there will be a separate TIFF image for each channel of each zposition of each time point of a dataset (assuming xyzt mode is used). You may save Overlays, like micron bars, by selecting Burn-in annotations during Save As or Export. A text file which contains the instrument parameter settings for every image in an experiment is saved along with the individual TIFF files making up the dataset in the experiment directory.
