OPERATION OF THE LEICA TCS SP5 II

YOU MUST SIGN UP TO USE THE LEICA SYSTEM OR COMPUTER EVERY TIME—NO EXCEPTIONS

YOUR EMORY ID # SHOULD BE GIVEN TO THE MiM CORE STAFF TO ALLOW KEY CARD ACCESS TO WMB 1011

Before attempting to use the microscope:

• you should grow or mount specimens on glass with 1.5 thickness (see MatTek dishes ordering information below). For a discussion on why this is important, see http://www.microscopyu.com/articles/formulas/formulascoverslipcorrection.html.

• you should read information on live cell imaging and issues such as photobleaching. A good place to start is http://microscopyu.com/articles/livecellimaging/index.html.

• you should also know the excitation and emission spectra for your particular fluorochromes so that you can select the proper configurations available in the software. See the charts with this information at http://www.mcb.arizona.edu/ipc/fret/default.htm.

• the Leica TCS SP5 II has four lasers with the following lines for excitation: Lasers

Diode 50 mW with 405 nm emission line "Blue" argon multi-line 65 mW with 458/476/488/514 nm

emission lines "Yellow" diode 20 mW with 561 nm emission line "Red" 10 mW with 633 nm emission line

• Detector Channels TLD brightfield detector One internal detector channel (PMT) Three internal GaAsP detector channels (HyD)

• you should familiarize yourself with the choices of objectives on the microscope and the meanings of the markings on the objectives (e.g., the magnification, the numerical aperture (NA), the coverslip thickness requirements). To learn these markings and their meaning, see http://olympusmicro.com/primer/anatomy/specifications.html.

POWER UP Procedure for Leica TCS SP5 II

Record Steps Below on the Leica LOG SHEET 1. Starting up the Cube and Box environmental chamber and The Brick gas mixer: NOTE: The Cube ALWAYS STAYS ON so that the temperature inside the Box is held at 37° C. NOTE: The house compressed air TO THE VIBRATION TABLE ALWAYS STAYS ON (on the wall behind the Leica). Make sure the deionized water level in the humidifier column inside the environmental Box is filled to the black mark. If necessary, add deionized water. Turn on the valves (1) on the house compressed air (mounted on the wall to the left of the CO2 tank) and (2) on the CO2 tank. If these pressures are not correct, contact Lu Hilenski, WMB 329, 404-727-8116.

Air pressure should read between 0.8-1.2 bars or 11.6-17.4 psi

CO2 pressure should read between 5-7 bars or 11.6-17.4 psi

Hilenski February 2013 http://medicine.emory.edu/MIMCore

Turn on the Brick. You should see bubbles in the humidifier column inside the environmental Box.

Start the Hardware 1. Turn on the Leica mercury lamp power supply. The green power light and the yellow shutter light will come on. Be sure to record in the log sheet the number of hours displayed. Once turned on, the lamp should remain on for a minimum of 30 minutes. 2-5. Turn on the PC Microscope switch (#2), the Scanner Power switch (#3) and the Laser Power switch (#4). Then turn the key to the Laser Emission switch (#5) clockwise to the On-1 position.

Start the Software 6. Login to your Windows account with your login and password you created in your training session. Wait for 45 seconds before proceeding. 7. Double click on the LAS AF icon to launch the software. 8. Make sure that machine is checked under Configuration. NOTE: Usually, Configuration is machine and Activate Resonant Scanner is UNCHECKED. However, the selections from the previous user will become the default, so PLEASE CHECK CAREFULLY before clicking OK. 9. If you need to use the resonant scanner, check the box Activate Resonant Scanner.

10. IMPORTANT: Read below BEFORE proceeding. When the Microscope Stand windows appears, select No unless you plan to use the Tile or Mark and Find functions for the motorized stage. NOTE: If you need to initialize the stage, you must first tilt the transmitted light arm (condenser arm) back from the stage, because the motorized stage might possibly hit the condenser during initialization. Then click Yes.

If YES, then tilt condenser arm UP. 11. Click on the Configuration tab and select Laser. 12. In the Laser Switch box, activate only the lasers you need by checking the boxes. If you are using the Argon laser, type in 25% in the box. Click ENTER on the keyboard.

Place the appropriate immersion media (EXCEPT for the air lenses 10x and 20x) on the objective lens. Place your sample on the microscope stage. BE VERY GENTLE--the stage is very delicate. Position the sample over the lens using the stage controller on the SmartMove and focus using the Z axis wheels (either Fine or Course settings). 3. After you have focused the sample, set the upper focus stop by pressing both SET + Z on the right front of the microscope until the Z position on the LCD panel on the front of the microscope reads 0 μm. (NOTE: If the upper focus is not set, the display will read --.--mm). Press together

Image Optimization 1. In addition to setting the proper dynamic range (few blue, few green pixels in glow scale), there are other adjustments to improve image quality:

Line Average or Frame Average. The sample will be scanned several times (line by line or frame by frame) and the average will be displayed.

Slowing the scan speed. Averaging and slowing the scan speed will slow down the acquisition speed, thus increasing photobleaching. Increasing Format will increase image resolution. Opening the Pinhole (check Pinhole, then set number using slider) allows more light to the

detector, but also allows more out-of-focus light to reach detector. A pinhole of Airy 1 results in the best resolution in the Z axis.
