However, unless the experiments are performed with a deep understanding of these limitations, this method of detection is an approximation at the best and often nonquantitative if used inappropriately. The scientific community has largely ignored these challenges, mostly because of a common misperception that film produces the highest quality data from western blots. These problems stem from a low-dynamic range of detection and the difficulty in accurately determining the limit of detection. Thus, editors and reviewers of scientific journals are looking at western blot results, particularly at the densitometric analysis to determine the fold differences in protein expression, with greater scepticism, often requesting the raw data files.Ĭhemiluminescent western blot data, derived from film-based detection, poses distinct challenges in producing quantifiable, reproducible data. This underlines the negative perception by which the scientific community views the western blot data. ![]() A recent report predicts that approximately 25 % of the accepted papers include at least one inappropriately manipulated figure and many of these are associated with western blotting. These include challenges related to every step of the western blotting procedure, from sample preparation, normalization, SDS–PAGE gel loading, protein transfer, primary and secondary antibody selection, incubations, and washes, detection method selection to densitometric analysis. However, there are many potential stumbling blocks in this procedure that can preclude reliable results. This multistep method determines the presence or absence, size, and modification or degradation states of target proteins, as well enables the quantitation of proteins from complex protein mixtures or homogenates.

In its place, LICOR has released Empiria Studio, a commercial product. Image Studio™ Lite is free image processing software used for quantitation of Western blot images and images from related experiments.Īs of 2021, Image Studio Lite has been discontinued and is no longer available for download. bio /products /software /image _studio _lite /
