A western blot is a laboratory method used to detect specific protein molecules from among a mixture of proteins. This mixture can include all of the proteins associated with a particular tissue or cell type.

How do you interpret western blot results?

To know how to analyze western blot data, Look for the sizes of the bands. These will be represented by a number, either followed by “kDa” or preceded by “p.” This is the size of the protein which has been detected and is the scale on which the proteins are separated in a Western blot.

What information does the western blot provide for each sample?

Western blotting is incredibly informative for determining the effect of time on a protein. For example, if each sample is a protein mixture of cells that are in different phases of the cell cycle, then western blotting will reveal how much a protein is present or absent during each phase.
