How do you present a Western blot image?
When presenting a western blot in a Starr lab meeting or presentation, include the following information: Title: Date, protein(s) and cell lysates including conditions being analyzed. Subtitle: Your initials, and date where details can be found in your lab book (see Lab Book Details).
How do you use densitometry in Image J?
Densitometry using ImageJ
- Click the centre of the square and drag it across to the next lane.
- For the last lane, repeat the procedure but press Ctrl and 3 to set the last lane.
- Use the line tool to draw the lines to eliminate the lane background from the calculations.
- Go to: Analyse→Gels→Label Peaks to get the report.
How does a western blot work in ImageJ?
Figure 1. A fabricated western blot image opened in ImageJ. The information along the top of the image indicates that the image is currently in 8-bit mode, using an inverting LUT (look-up table). The inverting LUT ensures that dark bands will be recorded as higher density values.
How to convert a western blot to grayscale?
The simplest method to convert to grayscale is to go to Image>Type>8-bit. Your image should look like Figure 1. Figure 1. A fabricated western blot image opened in ImageJ. The information along the top of the image indicates that the image is currently in 8-bit mode, using an inverting LUT (look-up table).
Which is the best scanner for Western blots?
ImageJ is a Java based (runs on all operating systems) freeware by Wayne Rasband from National Institute of Health (USA) and is available for download at: http://rsb.info.nih.gov/ij/. 1 Scanning The Western Blot Film. It is best to use a transparency scanner (scanner with light source on both sides of the bed).
How are protein bands from Western blot films quantified?
This protocol will allow you to relatively (no absolute values) quantify protein bands from western blot films. The quantification will reflect the relative amounts as a ratio of each protein band relative to the lane’s loading control. The same technique can be used for quantification of DNA or RNA from films.
