A post-doc researcher has found that thousands of commercial antibody products are marketed using images that show signs of manipulation similar to the kind that would trigger a retraction if found in a scientific paper. Reese Richardson of Northwestern University first noticed the issue in May, and after refining his search with collaborator Sholto David, identified problematic images across more than 17,000 antibodies sold by 16 different suppliers. The findings matter because researchers rely on these marketing images to judge whether an antibody will work reliably, and misleading data can send scientists down costly, time-wasting troubleshooting paths when the product itself is at fault.

Antibodies are essential tools in biology labs, used to locate proteins within cells, identify which tissues produce them, and confirm their presence on gels. Suppliers typically showcase experimental images to prove their antibodies perform well, but Richardson and David found manipulations ranging from removed background noise to copied and pasted data, affecting nearly 7% of the images they examined. Nature's reporting on the findings included mixed responses from the implicated companies, with some pledging to investigate and others dismissing the concerns, despite the frustration such issues cause researchers whose experiments fail to work as advertised.
