Or if more than one blob is present (i.e. blobs at different molecular weights) for a supposedly selective and specific antibody that should show exactly one blob on the blot.
> Now, if while preparing the images they needed to do some editorial choices
Editorial choices on raw scientific data are a big no-no.
I don't think you can find a picture in an article that hasn't been photoshopped in one way or another (which is mostly ok as long as it is not misleading)
Edit: TF's reply is interesting https://www.thermofisher.com/es/es/home/life-science/antibod...
Basically they say they are reviewing the images
(Also journals are usually more rigorous than marketing material)
Still part of the article.
> would be more worried if the blotted area was different (the dark blob) - or if data in a datasheet (something like test specificity, level of detection, etc) was wrong
These images are provided on the datasheet and form the basis for the level of detection / specificity claims
