Step 1: Import the image of Lignin stained tissue section into image analysis software.

The image will open in a new pop up window as shown.

Step 2: To split the section into different channels follow, image ---> color ---> split channels.

A new pop window will open, which will show the tissue section in three channels: green, blue and red.

Step 3: Select any one of the image that will be easier to analyze (Select a clear image). Here tissue section in green is selected for further analysis.
Step 4: Then adjust threshold to find the intensity of lignin staining. Follow, Image ---> Adjust ---> Threshold

While adjusting the threshold, select the lignin stained region of the imported image.

Step 5: Using the free hand selection tool, select the stained region of the imported image.


Step 6: Set measurements to find the intensity of lignin stained region. Follow Analyze ---> Set Measurements. Select the options Area, Integrated density, Area Fraction, Limited to threshold and Display Label in the Menu. Then click OK to analyze the image.

Step 7: To quantify the lignin stained area in the imported image, follow Analyze ---> Measure

A new pop up window will show the results of the tissue section.

Result Interpretation:
Percentage Area indicates the amount of lignin in the selected stained region. Here, 23 percent of the total selected region (Total Area 87181) is lignin.
