= Quickly Assessing Fluorescence Bleaching in LSM700 Microscopes with ZEN and Fiji=
== Protocol ==
=== Initial Settings ===
- On the LSM700, make sure you have all settings (Laser, Gain, Pixel Size, Speed) as you would want them
- Do not use averaging or Z stacks
=== Prepare for acquisition ===
- Check the {nav Regions} tool in ZEN and create a rectangle in a region of your image that contains signal
- In the {nav Regions} tool, uncheck **Bleach**, but keep **Acquisition** & **Analysis**
- Check **Fit frame size to bounding rectangle of regions**
- Check {nav Time Series}
- Use 100 timepoints (or more if you want)
=== Run Acquisition ===
- Use {nav Start Experiment }
- Switch to the **Mean ROI** tab on the left of the image
=== Copy the data and run the macro ===
- On the table, {nav right click} and select **Copy Data**
- Open Fiji and open the macro `Assess Bleaching.ijm` (Drag & Drop the file into Fiji)
{F10627035}
- Run the macro. It will use the data that is currently on the Windows clipboard and return the results
=== See the results ===
{F10627023, size=full}
There will be a message with number of frames before 50% of intensity is lost.
This is also reflected in a new line in a Table called Bleach Assessment
Finally, you can observe the plot to see if the exponential fit worked.
