It is intentional fabrication: it requires a lot more brain cycles to surreptitiously produce false data, it would literally be less work to Prepare the Western blots and scan them. Its the stuff they sell, so they have ready access to the products and would be much easier and cost-effective to simply perform (if it worked). Only if the product is known not to perform as specified is there a profit incentive for fabricating such "evidence".

It's more than just false advertising, it's criminal negligence wasting research attention, research time (repeating experiments to understand whats not working), naive nameplate quotations in the scientific literature also corrupts the scientific record (the author knows they are simply restating the nameplate specifications, but the reader may confuse it as a claim by the author).

Wondering if its sort of OK because it might just be marketing material, think of how the tobacco and other lobbies manipulate the scientific record. I mean technically it is marketing material... if one cynically views the scientific record as a poster wall where the highest bidder is allowed to plaster their spam all over the place.

I think it is technically marketing material, but if you have to fabricate your marketing material, that's not a good sign that the material is accurate. If I buy a car based on an advert where it shows the car going at 300 mph, and in real life it maxes out at 30mph, that's misleading advertising and something should be done about it.

Given that "at Thermo Fisher, a single vial containing a 0.1 mL aliquot of antibody solution typically costs 400 to 500 USD", you'd want to have accurate marketing material before buying it

Doing a western blot right takes a bit of practice and there are a couple failure modes you need to watch out for. Stuff like background "noise", smears, drifts can make it hard to get binary decision out of your experiment. E.g. antibodies are usually very very specific, but they can have impurities, unspecific bindings to other proteins etc which make interpretation harder. If they remove these from the advertised images you'll have a hard time comparing your own results to them. ESPECIALLY if they remove whole bands from the gel picture, which imho should be very much verboten.

Typically these catalogues have some numbers with regards to the antibodies binding affinity / impurities so you can have a general idea of what to expect, but having a clean image might mislead you into thinking that you did something wrong in your own setup. Seeing how wide spread it is, it's easy to imagine that their own lab is not run very "cleanly" and they have antibody contaminations in their gels, or issues with their own protocol that they're trying to edit out. Doubt that's the case, but it's really not a good look.

I'd treat this about the same as datasheets for mechanical or electrical parts.

When I buy an electronic component as a regular consumer I expect the datasheet "typical" values to be accurate 90% of the time. I can imagine larger industrial customers would really raise a stink if it's worse than that. However, any critical components in my circuit must be verified and "binned", and that's on me.

Without engaging in your point, small nitpick: These are images of Western blots[1], not PCR.

From the comments on the article by the author it looks more like 10% so far and they haven't systematically looked. That means ~10% if a probable floor of how much fraud there is.

     More like 10%, but my search has not been systematic. I am mostly looking where I know I will find image issues based on image filenames and “Find Similar Images” searches.

No marketing or design company would duplicate a band from another experiment (taking care to rotate it to make it look different nonetheless). Even in that unlikely scenario, Thermo Fisher is still responsible for the scientific data they publish.

The background painting could maybe be explained like this (depending on what was hidden), but I don't think the duplicated blobs have a good explanation, especially because some were rotated to try to hide the manipulation.

I disagree. If you look at the photos the painting used to make black blobs shorter. As I understand, black blob vertical position is the weight of a molecule, and they want to hide the fact that there are heavier or lighter molecules. So originally there was a long blob, and they made it look shorter.

More pretty, which would signify that the sample has less impurities -> better value

Some are just completely fabricated so it's hard to say if they have equivalent uglier images with real data...
