alt Hacker NewsExactly what is the "data" that's being shown here? Is it essentially some kind of marketing material showing "this sort of thing is what you should expect to see" or is it actually data or for compliance? If it's essentially marketing material or an instructional example that isn't meant to be representative it being magically clearer than real life doesn't seem like a great sin (unless it's being claimed it is representative). If it's something to be relied upon for compliance or as data to be used, that's pretty damming.

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.
When you’re deciding which antibodies to buy you’ll look at these figures to get a sense of their quality. Antibodies aren’t perfect and might bind proteins unrelated to the one you want to study. Depending on your application, some off-target binding might be acceptable, but usually it’s not. Also, they might just be completely nonfunctional and bind nothing (perhaps due to missteps during manufacturing).
So what this fraud does is convince you to give these antibodies a chance when you otherwise wouldn’t have. You should validate them yourself and show they only bind your target before doing an experiment, but now you’re just wasting time and money evaluating something that’s guaranteed to fail.
Antibodies are notoriously unreliable, so you might have to give two or three vendors a try before you get one that works. Now I’m starting to wonder how much of that reputation is due to fraud and not just nature.
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.

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.
