Nature Flags 54 Senescence Papers for Misusing E. coli Antibodies

Summary
More than 50 cellular senescence papers appear to have used E. coli β-galactosidase antibodies to detect mammalian proteins, raising doubts about the reliability and reproducibility of their findings.
Scholto David identified 54 such papers and said the bacterial antibodies were unlikely to properly recognize β-galactosidase in mammalian cells, a key marker used to identify senescent cells.
Nature said the impact now must be assessed paper by paper; one author of a 2010 Cancer Research study said the mistaken antibody was used only in supplementary work and did not alter the main conclusion.
The problem fits a broader pattern in life sciences: David has previously linked more than 300 papers to another antibody mix-up, while researchers say confusing product names and weak validation help such errors persist.
Aled Edwards warned that incorrect antibody records could also mislead AI systems used for literature mining and disease-target prediction, widening the fallout beyond the original studies.
