Inconsistent western blotting results
WebA protein band is a feature that appears in a western blot image. A western blot image is made up of pixels, which contain information about how much signal was collected at each location in the image. A digital image of a blot can be thought of as data in three dimensions. Each pixel in a blot image has an x and y coordinate, in addition to an ... WebDec 18, 2015 · Blots imaged at different stages in the reaction, due to delays such as waiting for the darkroom, will be inconsistent. Even identical blots imaged at the same time can produce inconsistent results (see Fig. 1). Accuracy is further compromised by stripping and re-probing chemiluminescent blots to detect multiple targets.
