hello this is Sean Taylor field application scientist manager for bio-rad in Canada and Iamp;#39;d like to demonstrate now how to perform density metric analysis of gel or blot images using image lab software so what we have before us here is a file that contains a 1 amp;amp; 2 dilution series of a protein lysate diluted down from about 60 micrograms loading in 1 amp;amp; 2 so 30 15 7.5 all the way down to 6 to the sixth Lane and weamp;#39;re going to try and quantify using image lab the density of these more prominent bends that we see here and maybe a less prominent band here so to do density metric analysis with the software you use these toolbars so you have a tool box on the side here and Iamp;#39;m only going to demonstrate a couple of the tools in this module just to focus in on density metric analysis so it starts with the image tools and the image tools are used strictly to straighten an image or to rotate or flip the image vertically horizontally the custom rotat

Why does my western blot have so much background?

Western Blot possible causes solutions for high background Too much protein per lane. Titrate down the amount of protein loaded per lane. Insufficient blocking of non-specific binding. Adjust blocking conditions.

What are the improvements of Western blot?

The more essential improvements needed for improving confidence in the accuracy of western blots include better documentation of primary antibodies, better training of researchers to use quantification software, use of antibodies within their linear range and proper choice of a loading control.

How to optimize Western blots?

If the Western blot shows high background signal, revising the washing steps on the next run-through has proven to be useful. Increasing washing times and volumes will reduce background signal along with performing additional buffer changes or using a stronger detergent (e.g., SDS instead of Tween 20).

How to make western blots look better?

5 Steps to Reducing Background in Western Blots STEP 1: Use clean, fresh buffers. STEP 2: Use the correct blocking agent. STEP 3: Dont skimp on the wash steps! STEP 4: Find the best exposure time for your chosen detection method. STEP 5: Optimize your antibody concentrations.

Why is my Western blot blurry?

If you have run the gel at a high voltage for a short period of time, the proteins may not run in a uniform manner, causing blurry bands. Blurry bands can also occur if a mistake is made during the preparation of the running buffer, or if bubbles were trapped during the protein transfer stages.

How to get a clean Western blot?

Blocking is critical for clean blots. Blocking agents such as non-fat dry milk or BSA occupy non-specific binding sites resulting in lower background. Check to see if there is a preferred blocking agent and concentration for your antibody. A 1-5% blocking solution is usually recommended.

Whats wrong with my western blot?

Patchy and uneven spots on the blot are usually caused by improper transfer. If there are air bubbles trapped between the gel and the membrane, it will appear darker on the film. It is also important to use a shaker for all incubation, so that there is no uneven agitation during the incubation.

Why are my Western blots so dirty?

Blotchy, Flecked, Or Dirty Background These artifacts are most commonly the result of uneven coating of buffer or antibody, the membrane drying out, or aggregates forming in the antibody or blocking buffer. Follow the tips below to identify and solve the cause of your imperfect western blot background.
