> Nature reported that 54 cellular senescence papers may have used antibodies unsuited to their experiments, and five papers with Korean co-authors were included in the review.

## Key points

1. Nature published the findings in August 2026 after an independent researcher's review.
2. The Korea Institute of Oriental Medicine team says its data was supplementary and will be re-tested.
3. Thermo Fisher Scientific faced separate criticism in 2026 over manipulated antibody validation images.

## What did Nature report?

Nature reported in August 2026 that independent researcher Shoto David had identified 54 cellular senescence papers that may have used antibodies not suited to their experimental purposes. Five of the papers included Korean researchers, according to Yonhap News.

## Which antibody is in question?

The antibody in question detects beta-galactosidase, an enzyme whose activity appears in cellular senescence, a state where cells stop dividing. The antibody was made to target the version of the enzyme found in E. coli bacteria, not the mammalian form. Nature said this makes it less likely to recognize the enzyme in mammalian cells, which could weaken the reliability and reproducibility of the research.

## What does the Korean team say?

The Korea Institute of Oriental Medicine team, which published a paper in npj Aging in January 2026, said it chose the antibody based on earlier studies. It checked the supplier's website, Thermo Fisher Scientific, which listed the antibody as used in human, mouse, and rat tissues. The team said the data from this antibody was supplementary and did not greatly affect the paper's conclusions. It plans to repeat the experiments to confirm the results.

## Why does this matter beyond one paper?

Nature noted that the impact of the antibody issue must be judged paper by paper. The concern also extends to the supplier. In May, researchers challenged Thermo Fisher Scientific over about 100 western blot validation images in its catalog that appeared manipulated. In August, they reported more than 18,000 suspicious images across products from 15 companies.

## For international fans

This story is about research integrity rather than entertainment. It shows how antibody choice can affect scientific results, and why researchers across countries are rechecking published work.

## FAQ

### Are the Korean papers being withdrawn?

The reports do not say any paper has been withdrawn. The Korean team said its data was supplementary and it plans to re-run the experiments to confirm the results.

### What is a senescence study?

Cellular senescence is when cells stop dividing and enter a resting state. Researchers study it to understand aging and related diseases.
