Importantly, there are two filter sliders to attenuate light (ND = neutral density filters) one

on the filter changer just in front of the arc lamp housing, and one in front of the filter changer (Fig. 4).

The filter changer (back) slider imposes an ND2 (100x less light, or 1% illumination), and the scope

(front) slider produces 25% illumination. You should use as little light for live cell imaging as possible

(both sliders pushed in) to forestall photodamage. Most imaging can be done with only the 25% slider

pushed in (well suited for your eyes, too). You can use full light for dim samples, but be aware that you

are probably getting high autofluorescence and probes will bleach quickly. And remember to always

check your controls with the same illumination intensities!

Need special filters? Ask the staff about them... we have more filters than turret positions, so CFP, YFP,

Chameleon FRET, FURA, TexRed and Cy7 cubes are available but not installed.

How-To Do (non-ratio) Fluorescence Image Capture

Much of the configuration of the microscope is manual, but the software will queue you

with pop-up windows to change what needs to be changed by hand. Turn on the computer and logon; start

MetaMorph. MetaMorph (see Figure below) is configured to always start with the 20x objective in place

and cubes set to DIC. The software will pop up a window reminding you to change the objective to the

20x to start. The TASKBAR that pops up contains most of the buttons to select an objective, rotate in

filter cubes, select light paths, operate the camera, etc. If the taskbar does not open, you can find it under

taskbar, a small window will pop up to

tell/remind you if you need to change

something manually.

1) You should always use the main menu

(top bar) to open the ACQUIRE

menu. This menu gives you access to

camera controls. Other ACQUIRE menu

options include acquisition of multiple

wavelengths, Z series, timelapse, etc. Many

of those menus close after you use them, so

you'll have to go back and re-open them for

more data. If you are collecting multiple
