Researchers Flag 450+ Manipulated Antibody Images in Thermo Fisher's Catalog

Independent researchers Reese Richardson and Sholto David have catalogued more than 450 apparently manipulated images in the verification data Thermo Fisher Scientific uses to advertise its primary antibodies, with findings collected in a public Zenodo repository. The suspicious images include Western blots with bands that are identical under flipping or rotation, telltale Photoshop-style brushstrokes visible when contrast is adjusted, and copy-pasted blocks of background noise. In one striking pattern, a single background image appears across at least 50 different antibody listings, lightly edited so the protein band lands where buyers would expect.

The stakes are practical: antibodies are notoriously unreliable reagents, with one 2024 estimate finding over half fail in at least one application, and individual vials from Thermo Fisher run $400–$500. Scientists rely on vendor verification data to judge whether a product is worth buying, so doctored images push the cost of discovery onto researchers and contribute to broader reproducibility problems in biomedical literature.

Thermo Fisher’s response denies fabrication and frames the alterations as images that “may have been optimized for presentation and clarity” — a phrase repeated six times in its FAQ. Going forward, the company says it will label images where originals are unavailable. The authors invite readers to inspect the repository and judge whether duplicated bands and repeating backgrounds fit that characterization.
