Inconsistent western blotting results
WebFeb 8, 2024 · Remove Background noise: You must have observed a major problem in western blot analysis is the high background noise, such as one side of the blot being darker than the other side. It causes inconsistencies in your results. The issue can be solved using some software packages that calculate the background around the target protein. … WebInconsistent Western blotting results - (Jun/24/2008 ) Hi I would like to know what could be the steps in western blot that went wrong as my first results and second results were inconsistent? My first results showed downregulation. However, when I confirm it again, it remained the same. (no downregulation nor upregulation).

WebSubstrate availability affects signal intensity. The amount of substrate available to the HRP enzyme may be variable across the blot, which changes the rate of the enzymatic … WebWell-characterized antibody reagents play a key role in the reproducibility of research findings, and inconsistent antibody performance leads to variability in Western blotting and other immunoassays. The current lack of clear, accepted standards for antibody validation and reporting of experimental details contributes to this problem.

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.
