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
